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.
