Connecting the Load
Output isolation
The output of the power supply is isolated from chassis
ground. Any output terminal may be grounded, or an
external voltage source may be connected between any
terminal output and ground. However, output terminals must
be kept within

60 Vdc when metal shorting bars without
insulation are used to connect the (+) output to the (+)
sense and the (–) output and the (–) sense terminals or

240 Vdc of ground when metal shorting bars without
insulation are either replaced with insulated conductors or
they are removed from the terminals so there is no operator
access to the output conductors without insulation. A
chassis ground terminal is provided on the front panel for
convenience.
Multiple loads
When connecting multiple loads to the power supply, each
load should be connected to the output terminals using
separate connecting wires. This minimizes mutual coupling
effects between loads and takes full advantage of the low
output impedance of the power supply. Each pair of the
wires should be as short as possible and twisted or shielded
to reduce lead inductance and noise pick- up. If a shield is
used, connect one end to the power supply ground terminal
and leave the other end disconnected.
If cabling considerations require the use of distribution
terminals that are located remotely from the power supply,
connect output terminals to the distribution terminals by a
pair of twisted or shielded wires. Connect each load to the
distribution terminals separately.
