2. INPUT POWER CONNECTIONS
Attention:
External Video Cable Systems Must
Be Properly Grounded In Accordance With The
National Electrical Code, ANSI/NFPA 70.
The
EX70
and
EX70N
cameras 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
Figures 2 – 1
and
2 – 2
.
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.
