Wire the Isolator Module

1. Apply +V and -V power (24V dc) to the adapter through a removable

terminal block.

Screw terminals and spring terminals are provided.

ATTENTION

When connecting wiring, torque terminal screws to 0.8…1.0 Nm

(7…9 lb-in).

WARNING

Make certain that you power this device with normal 24V dc. Do not

use an intrinsically-safe power supply, such as the 1797-PS2E or

1797-PS2N, to power this module.

If you connect or disconnect wiring while the field-side power is on,

an electrical arc can occur. This could cause an explosion in

hazardous location installations. Be sure that power is removed or

the area is nonhazardous before proceeding.
