Siemens SIMATIC ET 200iSP

6.4.8 Wiring terminal module TM-RM/RM
DANGER
Threat to explosion protection in the Zone 1 and Zone 21 potentially explosive area:
The isolating or disconnecting of the cables for the actuators on the terminal module TM-RM/
RM may only be carried out in Zone 1/ Zone 21 when the rated load voltage (of the relay
contacts) is switched o󹪜. In zone 21, you may only open the enclosure of the ET 200iSP if no
explosive dust is present!
DANGER
Threat to explosion protection in the Zone 2 and Zone 22 potentially explosive area:
The isolating or disconnecting of the cables for the actuators on the terminal module TM-RM/
RM may only be carried out in Zone 2/ Zone 22 in the event of explosion hazard when the rated
load voltage (of the relay contacts) is switched o󹪜.
If there is no risk of explosion, then you may isolate and disconnect the lines for the actuators
on the terminal module TM-RM/RM in Zone 2/ Zone 22 with the rated load voltage switched on.
Properties
The terminal module TM-RM/RM is the interface to the actuators of the electronic module
2 DO Relay UC60V/2A. The terminals of the terminal module TM-RM/RM are designed in the
Increased Safety Ex e type of protection.
Requirements
• Switch o󹪜 the rated load voltage before you wire the terminal module.
• Observe the wiring rules.
Required tools
• 3.5 mm screwdriver
• Insulation stripper
Procedure
