Note: The output of the power source is isolated from the input line and floating with

respect to chassis ground. If needed, either side (HI or LO) may be grounded.

The output power cables must be large enough to prevent a total voltage drop exceeding the

programmed voltage limit or 135 Vrms across the terminals of the current source. Note that

wires must be sized to accommodate the maximum current that is available. Always use the

current rating size the wires.

Cable lengths must not exceed twenty-five (25) feet. For lengths greater than 25 feet, calculate

the voltage drop from the following formula:

2 X DISTANCE X CABLE RESISTANCE PER FT. X CURRENT = VOLT DROP

Note: Ensure that output cable lengths from Master and Auxiliary chassis to EUT are of

identical length.

Output Terminal Block – OUTPUT (TB1)

Each CS chassis has a single AC output terminal block. For tabletop operation of a single

chassis system, the output terminal block must be covered using the supplied AC Output safety

cover. The terminal blocks are large enough to accommodate required wire gauge sizes. The

terminal block is located in the upper left corner on the rear panel of the unit. (Looking from the

back).

Multi-chassis configurations have two or more output terminal blocks, one on the master CS

chassis and one on the auxiliary CS chassis.

For operation as a multi-chassis system, the outputs of all CS chassis' must be connected

together using the additional terminal blocks provided in the CS ship kit. Keep the wire lengths

between each chassis and this common terminal block the same.

See Figure 3-2 for output wiring diagram.
