4 Mounting
4.1 General Mouting Instructions
Mount the safety switching device in a control
cabinet (IP54).
Mounting: Snaps onto standard DIN rails to
EN 60715. The device is equipped with a latching
element at the rear for fixing onto a standard DIN
rail.
4.2 Dimensions
Device dimensions in mm (H/W/D): 100 x 22.5 x 120
5 Electrical connection
5.1 General Information for Electrical
Connection
The electrical connection may only
be carried out by authorised
personnel in a de-energised
condition.
5.2 Connection
Only the output contact 14/24 is a safety contact. To
guarantee the safety function, both output channels
13 and 23 must be wired in series. Otherwise, the
evaluation of the signals must be dual-channel with
the required safety level. The safety-monitoring
module is supplied with a bridge between output 13
and 23.
The output contact X1 is a signalling contact and no
safety contact.
To prevent the contacts from welding together, a
fuse (4 A slow) must be connected before the output
contacts.
5.3 Terminal Assignment

Switch operating voltage on at terminals A1 (+)
and A2 (-).

Closing the reset circuit: Connect the start/reset
button to terminals X2 and X3 .

Automatic reset: This function is realised by
bridging the terminals X2 and X3 .

Connect transmitter/receiver: Connect the brown,
white and green leads from the transmitter and
the receiver to the terminals bn , wh and gn
according to the wiring example.

Connect the safety terminal 14 and 24 to the
machine circuit.

Signalling output X1 is no safety output and must
only be used as an optional signalling output
(NPN open collector)

Important details in the section “Technical Data”
should be noted and adhered to.
5.4 Commissioning
The safety function of the safety-monitoring module
must be tested. The following conditions must be
previously checked and met:
1. Correct fitting of the safety-monitoring
module
2. Fitting and integrity of the power cable
5.5 Operating Principle
When the operating voltage is switched on, the
safety contact 14/24 is open and the signalling
contact X1 is high-impedance.
To start the unit, the reset button must be actuated
for min. 1.5 seconds.
