Attention: External Video Cable Systems Must
Be Properly Grounded In Accordance With The
National Electrical Code, ANSI/NFPA 70.
The EX40N camera units are pre-connected
with an electrically isolated power board (VRB)
for 24V ac or 12V dc operation, with no change
to the polarity of the wires.
The VRB also connects to the camera and to the
Line Lock Board (if available).
See Figure 2 – 1 on page 7.
NOTE:
For DC input, the input voltage range is
10.5V dc to 40V dc.
The recommended input current from the power
supply should be approximately 1 Amp.
For AC input, the input voltage range is 12V ac
to 28V ac.
The recommended input current from the power
supply should be approximately 1 Amp.
