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 MONITORNG 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.
