5.2.3 Make the connections
The unit has connection terminals on flying leads. In wet or
outdoor installations make use of a field wiring box with Nema3
or IP55 protection level or better. Make the connections inside
the water tight compartment. After connections are made
ensure that the watertight compartment is tightly closed and
cables and conduits are properly sealed to prevent ingress of
water.
Cable tree
Use the following table to identify the wires in the cable tree:
Power connection
1. Use a class 2 power supply 24 VAC or +12 VDC.
2. Connect the power wires (red+ , brown-) to the power
supply connector.
3. Connect the earth wire (yellow/green) from the
camera to the system earth of the installation to ensure
correct EMC/RFI and safety protection.

For a DC supply the polarity is important. Incorrect polarity
does not damage the camera but it will not switch on.
