Introduction
This High Bay and Low Bay lights are designed for
illumination of industrial locations and use the latest in
solid state lighting technology for long life, low
maintenance, and high efficiency.
These unique optical design focuses light downward to
where it is needed, giving improved efficiency over a
conventional HID luminaire.
For 100-277VAC models:
An internal power-factor-corrected supply allows it to be
used at a nominal 100-277VAC (except for
H(E/F/J)*****P**** and occupancy sensor models; see
notes below), 50/60Hz AC supply without any variation in
light output. For supply connections, use suitable cable
rated for 100-277VAC, 18AWG and at least 90ºC. This
luminaire is IP66 rated and is suitable for indoor and
outdoor applications.
For 347-480VAC models:
An internal power-factor-corrected switch-mode supply
allows it to be used from any nominal 347V-480V,
50/60Hz AC supply without any variation in light output.
For 120-250VDC models:
An internal switch-mode supply allows it to be used from
any nominal 120-250VDC without any variation in light
output.
All models are suitable for use in dry locations per UL1598.
For models suitable for use in wet locations per UL-1598
and Outdoor Type (Salt Water) per UL-1598A; see outside
label of unit.
Models with the suffix PW are also suitable for
applications where high pressure wash-down is used to
clean and sanitize equipment.
WARNING: Surface temperatures of models with the
prefix Hx6, and Hx7 may exceed 100°C (212°F) in some
operating conditions. End user and installers are
responsible for installing these fixtures in an appropriate
and safe environment.
Recommended mounting height:
High Bay: 20-40ft [6-12m]
Low Bay: 12-20ft [4-6m]
NOTE: H(E/F/J)E*****P**** versions are rated for 110277VAC only.
NOTE: Models with integrated occupancy sensor are
rated for 110-277VAC only
General Mounting Information
For maximum long term reliability and light output, the
light must be installed in free air. The High/Low Bay
luminaire design incorporates an over-temperature
control circuit that reduces input power should internal
temperatures reach a maximum level. As a result, light
output may be temporarily reduced at higher ambient
temperatures.
WARNING: Figure 2 only applies to Vigilant series High
Bays (HE & H2 series).
The High/Low Bay luminaire is fitted with a 3m long cable
that can be extended if required.
Stirrup Mounting Information
The ‘Stirrup Bracket’ is fixed into place using 2 bolts and
the threaded holes on the side of the luminaire. When
secured into the desired position the 2 bolts should be
tightened to 6 – 8ft.lbs. [8.0 – 10.0Nm].
Pendent Mounting Information
The High/Low Bay fixture is threaded for ¾”NPT in order to
be assembled to conduit.
•
•
•
•
•
Calculate and measure required conduit length.
Feed the power cable through the conduit and
into the junction box.
Attach the fixture to the conduit using Teflon tape
or pipe sealant.
Insert ¼-20 anti-rotation screw in order to secure
the fixture to the conduit.
Note: For model number prefix HB6, HB7, and HBE
the alignment bar on the top of the fixture
corresponds to the major axis of the “narrow oval”
light pattern.
Installation of Luminaire (Electrical Connection)
The High/Low Bay luminaire is supplied with a 3 core
colored cable.
Note: Electrical installation of the extension should be
carried out by a qualified electrician.
For single phase units, 100-277VAC connecting the fitted
power cable conductors is as follows:
- Green wire connects to Safety Ground (Earth).
- Black wire connects to Live.
- White wire connects to Neutral.
When using 208V (two 120V phases) connect the black
wire to one phase and the white wire to the other phase.
Since the light fixture does not have an internal fuse on
the white wire (as it is normally the neutral), a fuse may
be connected in series with the white wire if required.
For 120-250VDC connecting the fitted power cable
conductors is as follows:
- Green wire connects to Safety Ground (Earth).
- Black wire connects to Negative (-).
- Red wire connects to Positive (+).
For single phase units, 347VAC (Figure 1) or 480VAC
(Figure 2) connecting the fitted power cable conductors
is as follows:
- Green wire connects to Safety Ground (Earth).
- Black wire connects to Live.
- Red wire connects to Neutral.
For two phase units, 480VAC (Figure 3) connecting the
fitted power cable conductors is as follows:
- Green wire connects to Safety Ground (Earth).
- Red wire connects to Line 1.
- Black wire connects to Line 2.

UL-1598 Rated LED High/Low Bay Luminaire
Interfacing to a PIR or Occupancy Sensor
The Dialight High/Low Bay fixture is ideally suited for control
by an occupancy sensor in order to maximize energy
savings based on its instant-on behavior and low power
consumption. Instructions for connecting the High Bay
fixture to an occupancy sensor are listed below.
Important Notes
- The low voltage Dimming wires are connected to the
grounded output section of the driver inside the light.
Never connect either one to the Hot or Neutral supply
wires.
- The ‘-‘ wire (Black) is at ground potential.
- Never use these wires for any purpose other than
dimming.
WARNING: To be installed and/or used in accordance
with appropriate electrical codes and regulations.
WARNING: Controlling a load in excess of the specified
ratings of the occupancy sensor could damage the unit
and pose risk of fire, electric shock, personal injury, or
death. Check load ratings to determine the unit’s
suitability for your application.
WARNING: To avoid fire and electrical shock, turn off
power at circuit breaker or fuse and test that the power is
off before wiring.
The Dialight High/Low Bay fixture is also ideally suited for
control by an external occupancy sensor (not provided by
Dialight) in order to maximize energy savings based on its
instant-on behavior and low power consumption.
Instructions for connecting the High Bay fixture to an
occupancy sensor are listed below.
1) Install occupancy sensor as per sensor instructions to
provide desired coverage of area.
2) Connect luminaire wires as follows:
For 120-277VAC operation:
Black lead to load of the occupancy sensor, White lead
to the line (neutral), Green lead to earth ground.
Multiple luminaires may be connected to a sensor, as
long as the rated load of the sensor is not exceeded.
3) Restore power at circuit breaker or fuse.
4) Verify operation of system. If the light will not turn on,
check the operation of the luminaire and sensor
individually and check that the wiring is done correctly.
If the light will not turn off or turns off and on quickly, see
the sensor’s installation instructions for further guidance.
Dali Controls
When using a Dali network, a 2 conductor, 18AWG,
plenum-rated cable is provided for connection. The
cable jacket is red in color and contains one black
conductor and one red conductor. DALI employs a
diode bridge so devices can be wired without regard for
polarity. A standalone system can control up to 64
devices.
Connect the DALI control wires to an appropriate DALI
bus. NOTE: The DALI bus cannot exceed 300 meters in
length. Do not connect DALI control wires to Live or
Neutral supply wires. Never use the DALI control wires for
any other purpose than to connect to an appropriate
DALI bus.
To properly configure the luminaire for use on the JenNet
Wireless network, please refer to the applicable
controller documentation. NOTE: The maximum
distance between any two luminaires or controller must
be less than or equal to 70 feet.
Dimming Models Only
The Dialight High/Low Bay fixture supports variable
dimming through a two wire interface. Using this
interface, it is possible to reduce the light level of the
fixture, saving energy and setting the level exactly as
desired.
The dimmable High/Low Bay has a single cable (five
wires total) interface. The power cable houses two wires
which are used to power the unit (Black and White, Hot
and Neutral, respectively), one which is used as a safety
ground/Earth (Green), and two wires (Violet and Gray)
which form the dimming interface and can be used in
the ways described below.
For 480VAC operation:
Red and black leads to load of occupancy sensor,
green lead to earth ground. Multiple fixtures may be
connected to a sensor, as long as the rated load of the
sensor is not exceeded.
2) Step dimming
Simply shorting the two wires together will cause the light
to dim to a low level. When this is done, the light will dim
down to approximately 30% of its full light output, with a
corresponding decrease in input power.
Red (plenum) OR Violet wire connects to DALI bus
Black (plenum) OR Grey wire connects to DALI bus
JenNet Wireless Controls
The High/Low Bay fixture contains integrated JenNet
Wireless controls that operate per IEEE802.15.4
standards.
For 347VAC operation:
Black lead to load of the occupancy sensor, red lead to
the line (neutral), green lead to earth ground.
1) Variable Voltage Control
An analog 0-10V active dimmer may be connected to
the two wires to control the light output of the fixture.
Multiple lights may be connected to the same dimmer,
as long as the maximum current rating of the dimmer is
not exceeded.
Secondary Retention
When using a safety cable for secondary retention,
ensure minimum slack (no greater than 1 foot) in cable
after installation. Connect safety cable to outer band of
fixture. Cable type, size, material, and attachment
method to meet customer application and to be
appropriate with all local and regional regulations.
Chemical Compatibility Guide
The chemical compatibility data referenced in this
manual was supplied by the raw material manufacturers
and is intended as a general guide. The data represents
the basic material properties and does not necessarily
represent the performance of the final product due to
manufacturing process and design variations for each
final product. Chemical compatibility is highly
dependent on concentration, temperature, humidity,
and other environmental conditions and therefore the
customer assumes responsibility for evaluation of
gaseous or direct contact chemical compatibility at
their site prior to product installation.
www.dialight.com/pubs/MDTFCHEMRFLX001.pdf
Dimming is controlled by means of a 0-10 VDC signal
(to be provided by the installer) to control the level of
dimming. At 10 volts, the output of the unit is 100%; at 0
volts, the output will be approximately 30%. The DC
dimming voltage should not exceed 15 VDC. Increasing
the voltage from 10VDC to 15VDC will not result in
additional light output.
