CAUTIONS
G
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').
G
Do not run data and power cables adjacent to or
in the same conduit as line voltage mains
power.
G
SensorNet 485 networks require 22 AWG
unshielded cable. Do not exceed 32 devices per
cable run.
G
RS422 networks require 22 AWG shielded
cable. Do not exceed 10 devices per cable run.
G
Manchester networks require 18 AWG shielded
cable. Do not exceed 3 devices per cable run.
G
Always terminate the camera dome connected
at the end of a cable run.
G
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.
G
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.
G
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.
G
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!
