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 set-
ting.
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 re-
mote 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.
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 Off position and wait until the
front panel display has turned Off.
CAUTION
Terminals 12, 22 and 23 of J1 are connected internally to the
negative sense (-S) potential of the power supply. Do not
attempt to bias any of these terminals relative to the nega-
tive sense. Use the Isolated Programming interface option to
allow control from a programming source at a different po-
tential relative to the power supply negative.
