4.4.2 Resetting the SW1 switch

Before making any changes to the SW1 switch setting, disable the power supply output by press-
ing the front panel OUT button. Ensure that the Output Voltage falls to zero and the OUT LED is
Off. Then use any small flat-bladed screwdriver to change the SW1 switch setting.

4.5 REAR PANEL J1 PROGRAMMING AND MONITORING CONNECTOR

The J1 Programming and Monitoring connector is a DB25 subminiature connector located on the
power supply rear panel. Refer to Table 4-4 for description of the connector functions. The power
supply default configuration is Local operation, which does not require connections to J1. For
remote operation using J1 signals, use the plug provided with power supply (or equivalent type).
It is essential to use a plastic body plug to conform to Safety Agency requirements. If a shield is
required for the J1 wires, connect the shield to a power supply chassis ground screw.
