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 t he
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 J 1. 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 req uirements. If a shield is
required for the J1 wires, connect the shield to a power supply chassis ground screw.
4.5.1 Making J1 connections
-J1 Connector type: AMP, P/N:747461-3
-J1 plug description: AMP, P/N:745211-2
-Wire dimension range: AWG26-22
-Manual Pistol grip tool:
Handle:AMP, P/N:58074-1
Head:AMP, P/N:58063-2
-Insertion/Extraction tool: AMP, 91232-1
Before making any connection, turn the AC On/Off switch to the Of f position and wait until the
front panel display has turned Off.
