Cautions:
• Be sure to connect the GND (grounding)
lead of the camera and grounding termi-
nal of the power supply when using a
24 V AC (WV-CW484F) or 220 V to 240 V
AC (WV-CW480S) power source.
• Shrinking the cable-entry seal is a one-
time procedure. Do not shrink the cable
entry seal until it has been ascertained
that unit is functioning.
ONLY CONNECT THIS TO 24 V AC or
12 V DC CLASS 2 POWER SUPPLY.
(WV-CW484F)
• To prevent fire or electric shock hazard,
the UL listed wire VW-1 style 1007 should
be used for the cable for Input Terminals.
• Do not use a transformer larger than
10 VA.
• Cable Length and Wire Gauge
<WV-CW484F>
24 V AC
The recommended cable length and thick-
ness are shown in the table for reference.
The voltage supplied to the power terminals
of the camera should be within 19.5 V AC
and 28 V AC.

12 V DC
Use the formula below to calculate the power
cable and power supply. The voltage sup-
plied to the power terminals of the camera
should be within 10.5 V DC and 16 V DC.

Important:
When using 12 V DC power sup-
ply, the optional heater unit is unavail-
