these requirements could cause substantial voltage-drop power losses, terminal over-
heating, and insulation degradation.
The Output styles vary depending on the Output voltage range:

Platform A & B (Output Voltage Range: 7.5V-80V &100V-300V).
– Vertical Bus Bar Configuration
– 0.422 inch mounting hole
o 7.5V-25V models have two mounting holes
o 30V-300V models have one mounting hole
– Use 3/8 inch diameter bolt/nut.

Platform C (Output voltage range: 400V- 600V)
– Threaded-stud configuration
– M6 x1.0inch nut/washer size
The Output connections are protected with a metal cover. To connect the load cables,
remove the metal cover and connect the proper size cables with nuts and bolts.
Proper torque (as per bolt size) should be applied to any bolt/nut combination.
Typical cable sizes for load connections are shown below. Use cables that meet
requirements for current, voltage, length, temperature and termination.
CURRENT (Amps)
Io ≤ 50
50 < Io ≤ 100
100 < Io ≤ 187.5
187.5 < Io ≤ 333
333 < Io ≤ 700
700 < Io ≤ 1000

3.9.3. Load Cable Termination
The load cables should be properly terminated with terminals securely attached. DO
NOT use un-terminated wires for any load connections at the Power Supply.
Be careful when connecting the remote sense lines to the far end of the load
cables. Reversing the sense line polarity to the load, or leaving the +S or –S
3.9.4. Noise and Impedance Effects
To minimize any noise pickup or radiated noise, the load wires and remote sense
wires should be twisted pairs to the shortest possible length. Shielding of sense leads
may be necessary in high noise environments. Where shielding is used, connect the
shield to the chassis via a rear panel Ground screw. Even if noise is not a concern,
the load and remote sense wires should be twisted-pairs to reduce coupling, which
might impact the stability of the Power Supply. The sense leads should be separated
from the power leads.

CAUTION
sense lines opened, could damage the Power Supply.
