INSTALLATION AND SERVICE GUIDE 11
CAUTIONS
 For indoor domes, the maximum length of
power cable allowed between the Class 2 LPS
(low voltage) ac source, such as a J-box, and
the dome is 250m (820').
 Do not run data and power cables adjacent to
or in the same conduit as line voltage mains
power.
 SensorNet 485 networks require 22 AWG
unshielded
cable. Do not exceed 32 devices
per cable run.
 RS422 networks require 22 AWG shielded
cable. Do not exceed 10 devices per cable run.
 Manchester networks require 18 AWG shielded
cable. Do not exceed 3 devices per cable run.
 Always terminate the camera dome connected
at the end of a cable run.
 When using the RUPTB standard base and
wiring cables directly to the dome, ALWAYS
connect the video cable to the dome before you
connect the 9-pin cable (which contains power).
If you connect the 9-pin cable first, you risk
shorting delicate electronics near the
connector.
 I/O PC board (when used).
- If a cable clamp is on this board, remove it,
as it could damage cable connectors in the
housing during assembly.
- Use a jeweler’s 2.5mm (0.1") slotted
screwdriver to tighten connector screws. Do
not over tighten these screws.
- Use the dust cover when shipping the I/O
board back to the manufacturer. It will
protect the spring-finger connector.
 When connecting the housing and eyeball
assembly to an outdoor housing:
- Remove both
slot covers to keep the
camera from overheating.
- Keep cables entering the housing away from
the heater assembly.
- Place tubing around the BNC connectors to
avoid shorting their metal surface to the
outdoor housing.
- Check heater fans. Both fans must be on to
prevent overheating.
Note: For further information, see installation
instructions shipped with the outdoor housing.
 If disassembling the dome:
- Dome contains electrostatic-sensitive
devices! Use a ground strap when handling
PC boards.
- Once disassembled, parts of housing and
eyeball assembly are “extremely fragile” and
may break. Proceed using extreme care!
