Front-Panel Voltage and Current Limit Settings
You can set the voltage and current limit values from the front panel using the
following method.
Use the voltage/current adjust selection key, the resolution selection keys, and
the control knob to change the voltage and current limit values.
1 Select the desired range using the range selection keys after turning on the power
supply.

knob. If the display limit times out, press the
key again.
4 Set the knob to current control mode using the voltage/current adjust selection key.
5 Move the blinking digit to the appropriate position using the resolution selection keys
and change the blinking digit value to the desired current limit by turning the control
knob.

W a r n i n g
Floating the power supply output more than ±60 Vdc from the chassis presents an
electric shock hazard to the operator. Do not float the outputs more than ±60 Vdc
when metal shorting bars without insulation are used to connect the (+) output to the
(+) sense and the (-) output to the (-) sense terminals.
17
Chapter 1 General Information
Description
W a r n i n g
Outputs can be floated to maximum of ±240 Vdc provided that the 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. All field wiring insulation must be adequate for the voltage present.
