CAUTIONS
❏
If using an RS422 communication line, use
shielded cable and do not exceed 10 devices
per daisy chain.
❏
If using a SensorNet communication line, use
unshielded cable and do not exceed 32 devices
per daisy chain.
❏
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 the composite cable, or camera
power cable (if used), adjacent to or in the
same conduit as line voltage mains power.
❏
When 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 overtighten 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 the composite cable 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!
