IMPORTANT SAFETY INSTRUCTIONS
Please read before using your power supply.
CAUTION!
ALL ELECTRICAL INSTALLATIONS MUST
MEET LOCAL AND NATIONAL WIRING
CODES AND SHOULD BE PERFORMED BY A
QUALIFIED ELECTRICIAN.
COOLING:
If the module is installed in an enclosed case, forced air
cooling should be provided.
AC INPUT:
The power supply module should be operated from 120V
AC/60 Hz source with proper earth ground connection.
120V, 60 Hz AC input is fed through quick disconnects
marked “L” & “N”. The pads under holes S1,S3 & S4 (Fig.
1 on page 4), should be connected to earth ground. Color
code for AC input wires is:
NEMA INTERNATIONAL
QUICK DISCONNECT “L” BLACK BROWN
QUICK DISCONNECT “N” WHITE BLUE
PADS UNDER HOLES S1,S3,S4 GREEN GREEN / YELLOW STRIPE
