4.4.2 Resetting the SW1 Switch
Before making any changes to the SW1 switch setting, disable the power supply output
by pressing 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.
