WARNING
Turn Off the AC input power before making or changing any rear panel
connection. Ensure all live circuits are discharged and that all connections
are securely tightened before applying power. There is a potential shock
hazard when using a power supply with a rated output greater than 40V.
When local sensing, a short from +LS or +S to -V or -S or -LS,
will cause damage to the power supply. Reversing the sense
wires might cause damage to the power supply in local and
remote sensing. (Do not connect -S to +V or +S to -V).
3.9 CONNECTING THE LOAD
The load cables between the power supply outputs and the load must be a specified. The cable con-
nections must be secured to required torque spec. Failure to meet these requirements could cause
substantial voltage losses, terminal over-heating, and insulation degradation.
The output styles vary depending o the output voltage range.
Platform A & B (Output Voltage Range 7.5V-80V &100V-300V ).
– Vertical Bus Bar Configuration,
– 0.422 in. mtg. Hole,
– Use 3/8 in dia. Bolt.
Platform C (Output Range 400V- 600V)
– Stud configuration
– M6 x1.0 nut/washer size
The output connections are protected with a metal cover. To connect cables, remove the cover. Con-
nect the proper size cables with nuts and bolts.
Proper torque (as per bolt size) should be applied to the bolts.
Typical cable sizes for load connections are shown below. Use cables that meet requirements for cur-
rent, voltage, length, temperature and termination.

3.9.1 Wire termination
The wires should be properly terminated with terminals securely attached. DO NOT use unterm-
inated wires for load connection at the power supply.
