1. Install the mount for the pendant dome. Refer to the instructions supplied with the mount.
2. Open the hinged door to the back box. Push the tab lock towards the wall of the unit and lift the door open. Pull
wiring into the back box. Refer to Table A, Table B, and Table C for wiring distances.
3. Screw the back box onto the mount. If outdoors, apply thread compound (provided) to the threads on the back box.
NOTE: Thread compound must be applied. Not doing so may prevent the units from being separated in the future.
..
Note: Input power for the dome is 24 VAC or 24 VDC. Using 24 VAC input power, power consumption is 23 VA per dome
for indoors models and 73 VA for out models. Using 24 VDC input power, power consumption is 0.7 A (15 watts) for indoor
models and 3 A (65 watts) for outdoor models.
Use a 24 VAC transformer with the following minimum VA:
40 VA per dome For indoor models (without heater)
100 VA per dome For outdoor models (with heater)
NOTE: As a minimum, UTP requires Cat5, 100-ohm twisted pair cable
