7. On heater and heater/blower units, make sure the heater

and fan wires stay connected to the terminal block.

4.8 Video coax connection

See Table 3.2 and Table 3.4 for UHO-HBPS-10, UHO-HPS-50 and

UHO-HBPS-50 models.

1. Install a 1/2-inch NPT fitting into the available hole in the

rear cap.

2. Route the video coax cable through one of the fittings

installed in Step 1., or one of the feed-through fittings in

the base.

3. Attach the BNC connector to the coax and connect it to the

camera.

4. Pull any excess wire out of the housing and tighten the fit-

ting to 8.5 Nm to 9.0 Nm (75 inch-lb to 80 inch-lb). This

torque rating is approximately one to one and a half turns

past the point where the fitting starts to grip the wire.

CAUTION!

For security protection of the device, the branch circuit

protection must be secured with a maximum fuse rating of 16A.

This must be in accordance with NEC 800 (CEC Section 60).

CAUTION!

Use only cables meeting specifications in Section 4.3 Cable

requirements for wiring video coax connections.

CAUTION! Always securely tighten all fittings to ensure a liquid-

tight seal. Failure to do so could allow water to enter the

housing and damage the camera and lens. If a sealant is used,

be sure it is a neutral cure type. Sealants that release acetic

acid may harm camera electronics. Use of drip loops is

recommended on the wiring outside of the rear end cap.
