8 Pelco Manual C1917M (12/97)
8. Connect power to the camera (refer to Figure 8).
This camera must always be operated with a 24 VAC class 2 power supply. In
the U.S.A., use a power supply that is UL Listed. In Canada, use a power
supply that is CSA Certified. Refer to Table A for wiring distances.
When using a transformer without a ground lead (two-lead type), connect the
output of the transformer to the 24 VAC 1 and 2 terminals of the camera.
Connect a ground lead to the GND terminal or an irregular voltage may be
generated in the AC power cord and may cause malfunction and/or damage
to the video camera.
When using a transformer with a ground lead (three-lead type), connect the
ground wire to the GND terminal and the other two wires to the 24 VAC 1 and
2 terminals of the camera.
If you wire more than one camera from the same transformer, connect one
side of the transformer to terminal 1 on all of the cameras, and connect the
other side of the transformer to terminal 2 on all of the cameras. If all of the
cameras are not connected the same, the cameras will be out of phase with
each other and may produce what appears to be vertical roll when switching
between cameras.

WARNING:
Be sure to connect
the power and ground leads to the
appropriate terminals. Wrong con-
nection may cause malfunction
and/or damage to the video cam-
era.
