• To prevent fire or electric shock hazard, the UL listed
wire VW-1 style 1007 should be used for the cord for
Input Terminals.
• Do not use a transformer larger than 10 VA.

Caution:
• The following connections should be made by qualified
service personnel or system installers in accordance
with NEC 725-51.
• Wire colors & functions
Camera power cord
<WV-CW384>
Cautions:
• Be sure to connect the GND (grounding) lead of the
camera and grounding terminal of the power supply
when using a 24 V AC (WV-CW384) or 220 V to 240 V
AC (WV-CW380) power source.
• Shrinking the cord-entry seal is a onetime procedure.
Do not shrink the cord-entry seal until it has been ascer-
tained that unit is functioning.
