The equipment is built according to DIN / EN and checked and leave the plant according to security in
perfect condition. If, in any case the information in the instructions manual is not sufficient, please contact
our company or the responsible representative.
To maintain this condition, you must observe the safety instructions in this instruction manual titled
“Important Information”. Failure to follow the safety instructions may result in death, personal injury, or
property damage to the equipment itself and other equipment and facilities.
Instead of the industrial norms and regulations written in this instruction manual valid for Europe, you must
observe out of their geographical scope the valid and relevant regulations of the corresponding country.
Attention!
If the device is damaged it may not be put into operation if it must be suspected, that a safe
operation may be impossible. The input Reset 2 is not insulated from the sensor-input. If the sensor is
connected with e.g. a heating-element, the input Reset 2 is on the same potential. It has to be made sure that
this voltage cannot lead up to an electrical shock.

Installation
The device must be installed within rooms of international protection class IP 5x or better.
The device can be mounted:
•
on 35 mm mounting rail according to EN 60715
•
assembled with screws M4
•
Wiring directly to plug base, connect wires as per wiring scheme
Apply mains voltage to terminals A1 and A2. The lines of the sensor circuit are to be routed as separate control
lines
Observe the maximum admissible temperature when installing in a switchgear cabinet.
Make sure sufficient space to other equipment or heat sources. If the cooling becomes more
difficult e.g. through close proximity of apparatus with elevated surface temperature or
hindrance of the cooling air, the tolerable environmental temperature is diminishing.
Generally recommended minimum clearance is 20 mm.
The contacts of the reset push-button at terminal Y1, Y2 must be able to switch low current/voltages.
We recommend gilded contacts with small bouncing behavior to use.

Commissioning
Attention!
Temperature relays with supply voltage DC24V without potential separation
Are intended to use at power supplies SELV or PELV according EN 61558 / EN60742
where protected wiring is used.
Attention!
If the internal fuse has triggered, with high probability a failure occurred in the
Equipment. In this case, the device has to be reviewed and / or repaired in the
Factory! The device must not be repaired from the user and must be replaced
With a similar device.
The safety function must be tested additionally to recurring examinations with maintenance services.
- Short circuit test: bypass sensor terminals T1, T2
- Line interruption test: disconnect sensor line at terminal T1 or T2
If an error is detected no restart must be induced until the error is cleared.
