42 Operating Manual for XPR Series Power Supply
Single Load To connect a single load to the DC output bus bars (5–80V outputs):
1. Ensure that the power supply is powered OFF.
2. Place a 5/16 in. (M8) bolt in the connecting hole of the negative bus bar, and
fasten the negative wire or bus bar, a flatwasher, lockwasher, and a nut to the
bolt.
3. Using a wrench, turn the bolt until it is secure at approximately 25 foot-pounds
(34Nm).
4. Fasten the positive wire or bus bar to the positive bus, using a bolt, flatwasher,
lockwasher, and nut.
5. Tighten the bolt to approximately 25 foot-pounds (34Nm).
6. Ensure that the positive and negative wires are arranged so bare wires do not
come into contact with each other or the chassis.
To connect the DC output wire clamp connectors (100–600V outputs):
• Connect appropriately sized wires as described in steps 1 to 6 above, except strip
0.5 in. (13 mm) of insulation off each load wire, and clamp in the output
connector by securely tightening the vertical clamp screw for each output.
