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.

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

-Extraction tool: AMP, 91232-1 or equivalent.

-Manual Pistol grip tool:

Handle:AMP, P/N:58074-1

Head:AMP, P/N:58063-2

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 negative sense. Use the Isolated Programming interface option to allow control from a programming source at a dif- ferent potential relative to the power supply negative.

CAUTION

To prevent ground loops and to maintain power supply isola- tion when programming from J1, use an ungrounded pro- gramming source.

WARNING

There is a potential shock hazard at the output when using a power supply with rated output greater than 40V. Use wires with minimum insulation rating equivalent to the maximum output voltage of the power supply.
