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
ion of the connector functions. The power
supply default configuration is Local operation, which does not require connections to J1. For remote
eration using J1 signals, use the plug provided with power supply (or equivalent type). It is essential
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.

J1 Connector type: AMP, P/N:747461
Wire dimension range: AWG26
Extraction tool: AMP, 91232
Before making any connection, turn the AC on/Off switch to
the Off position and wait until the front
panel display has turned Off.

option to allow control from a
programming source at a di

To prevent ground loops and to maintain power supply isol
