D1 NW ANT 1 900 Antenna
IF 1572
Installation & Maintenance Information
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE
D1 NW ANT 1 900 antennas are UL Listed for the following locations: Class I, Division 1, Groups C, D, -40ºC ≤ Ta ≤ 85ºC.
WARNING
To prevent ignition of Groups C and D atmospheres, see Page 2 of this
Instruction Sheet for atmospheres enclosure is suitable for.
CAUTION
To reduce the risk of ignition of hazardous atmospheres, disconnect
equipment from supply before opening. Keep tightly closed when
operating.
DESCRIPTION
D1 NW ANT 1 900 antennas are designed for use in hazardous locations.
The antenna incorporates a flameproof barrier as well as a high quality
explosionproof antenna. The antenna is equipped with a female TNC
connector and a male 3⁄4” NPT fitting for quick installation.

CONDITIONS FOR SAFE USE
To reduce the risk of ignition due to electrostatic discharge, avoid
contact with the unit while an explosive atmosphere is present. Clean
only with a damp cloth. Do not use chemical cleaners.
INSTALLATION & FIELD WIRING
Mounting & Installation
D1 NW ANT 1 900 antennas are designed to be mounted in a female ⁄4”
NPT boss. Always use high quality 50Ω coaxial cable when connecting to
the antenna. To avoid unnecessary loss, the cable should be as short as
practical and contain as few connectors as possible. The antenna will
work in any direction, but vertical polarization is most efficient, and
matching the transmitter and receiver polarization is recommended. Many
factors can affect the performance of an antenna; generally, the higher the
antenna, the better. Line-of-sight to the receiver/transmitter is also
recommended. The overall performance will depend on many things,
including the distance between receiver and transmitter, obstructions,
radio power, RF noise, and Fresnal effect. This antenna is designed for
indoor and outdoor use, and includes a rainproof seal.
3
For installation in the USA, install in compliance with NEC® 500 or NEC 505
as applicable. For all other areas, check local electrical codes for required
installation parameters.
Connect the antenna as follows:
1) Ensure all equipment is off before installation and that area is clear of
potentially explosive atmospheres (see Page 2 for a list of acceptable
atmospheres).
Antenna to be mounted via the 3⁄4” NPT supply connection in an enclosure
or other suitable device (e.g. conduit).

1) Base to radome joint base: 1-3/8 - 18 - UNEF - 2A; Radome 1-3/8 - 18
- UNEF - 2B, 7 threads engaged.
2) Connector to base joint: 3/8 - 32 UNEF 2B, 12 threads engaged
3) Set screw to base joint: #10-32 UNC 2B, 6 threads engaged
Antennas have not been evaluated for resistance to light.
CALIBRATION & MAINTENANCE
The antenna has no serviceable parts and requires no adjustments or
maintenance. Do not attempt to disassemble the antenna (doing so can
damage the antenna).
2) Attach 50Ω TNC coaxial cable to the antenna and tighten.
Optional Equipment:
• Right angle mounting bracket for pole mount.
3) Attach the antenna to the 3⁄4” NPT of a suitable enclosure. Using a
1.25” wrench, tighten so that there is at least 5 threads of engagement.
WARRANTY
4) Connect the cable to the transmitter/receiver.
D1 NW ANT 1 900 are warranted to be free of defects due to workmanship
or faulty components for a period of one year after shipment.
5) If required, a ground may be attached to the antenna using the #10
grounding screw provided.
PROCEDURE FOR RETURNED GOODS
1) Obtain authorization from the factory by phone 866-764-5454 or fax
315-477-5179. Cooper Crouse-Hinds will assign an RMA number.
2) Carefully pack device and place RMA number on outside of box and
on packing list.
3) Device will be inspected by Cooper Crouse-Hinds and customer will be
notified of warranty.
