RES-401
Version 1
To increase operational safety and interference immunity, all 24VDC logic signals are electrically isolated from the
controller and the heating circuit.
The compact design of the RESISTRON
®
temperature controller RES-401 and the plug-in connections make this
controller easy to install.

Installation
See also section 1 "General information" on page 3.
Installation and startup may only be performed by technically trained, skilled persons who are
familiar with the associated risks and warranty provisions.
5.1
Installation procedure
Proceed as follows to install the RESISTRON
®
temperature controller RES-401:
1. Switch off the line voltage and verify that the circuit is de-energized.
2. The supply voltage specified on the nameplate of the RESISTRON
®
temperature controller must be identical
to the line voltage that is present in the plant or machine. The line frequency is automatically detected by the
RESISTRON
®
temperature controller in the range from 47Hz…63Hz.
3. Install the RESISTRON
®
temperature controller in the electrical cabinet on a standard top hat rail (DIN TS35
rail, according to DIN EN 50022). If several controllers are installed on one top hat rail, the minimum clearance
specified in section 8 "Technical data" on page 28 must be allowed between them.
4. Wire the system in accordance with the instructions in section 5.3 "Power supply" on page 10, section 5.6
"Wiring diagram" on page 13 and the ROPEX Application Report. The information provided in section 5.2
"Installation steps" on page 9 must also be heeded additionally.
Check the tightness of all the system connections, including the terminals for the impulse trans-
former windings.
5. Make sure that the wiring conforms to the relevant national and international installation regulations.
