Wiring terminal module TM-RM/RM
DANGER
Threat to explosion protection in the Zone 1 and Zone 21 potentially explosive area:
In Zone 1/ Zone 21, always switch off the rated load voltage (relay contacts) before you
disconnect the wires for actuators on terminal module TM-RM/RM. In zone 21, you may only
open the enclosure of the ET 200iSP when no explosive dust is present!
DANGER
Threat to explosion protection in the Zone 2 and Zone 22 potentially explosive area:
In Zone 2/Zone 22, if an explosion hazard exists always switch off the rated load voltage
(relay contacts) before you disconnect the wires for actuators on terminal module TM-RM/
RM.
If an explosion hazard does not exist, you may disconnect the wires for the actuators on
terminal module TM-RM/RM in Zone 2/ Zone 22 while the rated load voltage is switched on.
