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.
