Prior to installation, make sure that the power supply will be properly
ventilated for adequate heat dissipation.
• Do not cover the top or bottom surfaces of
the unit.
• When installing multiple units, leave enough
space between them for cooling.
• Forcing air over the unit(s) improves heat
dissipation.
Each of these DIN Rail Power Supply models
will attach to TS35/7.5 or TS35/15 DIN rails.
1. Insert the upper part of the DIN rail clip on the
power supply into the DIN rail track.

Connecting to DC Output: Insert the positive and negative wires into the
+V terminal contact (Pin 6 or 7) and –V terminal contact (Pin 4 or 5),
then tighten the terminal screws to prevent the wires from becoming
loose. NOTE: Always make sure that DC wiring is connected with the
correct polarity.
Connecting to AC Input: Insert the AC power lines into the Pin 1 and Pin 2
terminal contacts, then tighten the terminal screws to prevent the AC
wires from becoming loose.
Connecting to Ground: Connect the frame ground (Pin 3) of the power
supply to any nearby reliable ground with a thick wire to help ensure
safety and prevent system “noise.”
