Specifications, Installation, and Operating Instructions
Model:
SP 50 Family
CAUTION: The installation of a surge protection device (SPD) must be done by qualified electrical
personnel. SPD must be grounded through the power system ground for proper operation.
WARNING: Before installing the suppressor, AC power must be off. Failure to do so could result in damage to
the suppressor and poses a potential electrical shock hazard to personnel.
WARNING: Read SPD label on side of the enclosure to verify voltage configuration.
WARNING: Discontinue installation if the measured voltage is not in the range of the model voltage configuration
of the SPD being installed. Contact Transtector’s technical support with any questions concerning the voltage
configuration prior to installation and application of power.

Pre-Installation Notes
•
•
•
•
•
•
Read entire installation manual prior to installing this SPD.
Unpack unit carefully, removing packing material. Inspect for damages during shipment.
If unit seems damaged, contact Transtector and shipping agency. Do not continue to
install unit.
Confirm install location temperature will not exceed SPD rating (-40°C to +85°C).
Verify all nuts and bolts have tight connections.
Verify install location meets SPD enclosure NEMA type 4X location requirements.
Electrical Specification for SPD Installation:
Verify voltage configuration of the SPD matches actual system voltage configuration of
service point. Ground resistance is less than 25 ohms and all wiring conductors are in
accordance with appropriate layout/installation drawing.

Installation Procedure
•
Length of leads and conductor size:
Leads must be as short as possible, not exceeding the recommended length of a foot
and a half (1.5’); and routed with gradual bends avoiding sharp or 90° bends. SPD
comes with #12 AWG wire pre-cut for installation. Extending existing wire by splicing is
not recommended.
•
Mounting:
1. Turn off all power supplied to
this equipment.
2. Panel Mount: Punch out 1/2”
enclosure knockout from panel
or mounting location as close as
possible to where the wires will
terminate.
Please
consult
Transtector application support
where another type of mounting
is required.
3. Insert a 1/2” close nipple to the
Myers Hub provided and
attached to the SP 50 SPD.
Insert SPD wires carefully through the knockout hole. Tighten a 1/2” steel conduit
lock nut to secure the SPD to the enclosure (as shown in Figure 1 Panel Mount).
4. Connect the wires as shown in the appropriate wiring diagram.
5. Overcurrent Protection: Type 1 SPDs are UL Listed and tested to be selfprotecting. They do not require upstream protection according to UL 1449 3rd
Edition and Section 285 of the NEC. However, it is recommended an upstream
disconnect or breaker be installed for maintenance and safety. Many switches
and circuit breakers have limitations regarding more than one wire in a
connector. Breaker manufacturers can provide information on limitations of
available terminals. Where additional wires are prohibited under the same
terminal, many times installing a new circuit breaker is convenient. Typical sizes
are 15, 20 and 30 amps.
6. For optimal device performance, use shortest wire length possible. Cut off
excess wire. Avoid sharp edges.
7. Before energizing, installer must verify service and separately derived system
Neutral to Ground bonding jumper per NEC requirements.

Final check:
Check installation of unit as indicated in installation drawings. Apply external AC power
to the SPD. The unit is operational if all green indicator lamps are illuminated. If not,
contact Transtector’s technical support at 800-882-9110 or 208-772-8515.
•
Visual inspection:
Operational status of the SPD is verified by observing the phase status indicator LED(s).
The LED, illuminated Green indicates normal operation with all protection modes
functioning.
