The PFH value of 2.00 × 10
-8
/h applies to the combinations of contact
load (current through enabling contacts) and number of switching
cycles (n
op/y
) mentioned in the table below. At 365 operating days per
year and a 24-hours operation, this results in the below-mentioned
switching cycle times (t
cycle
) for the relay contacts.

3. Mounting
3.1 General mounting instructions
Mounting: snaps onto standard DIN rails to EN 60715.
Snap the bottom of the enclosure slightly tilted forwards in the DIN rail
and push down until it latches in position.
3.2 Dimensions
All measurements in mm.
Device dimensions (H/W/D): 73,2 mm x 45 mm x 121 mm
4. Electrical connection
4.1 General information for electrical connection
As far as the electrical safety is concerned, the protection
against unintentional contact of the connected and therefore
electrically interconnected apparatus and the insulation of the
feed cables must be designed for the highest voltage, which
can occur in the device.
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
Wiring examples: see appendix
To avoid EMC disturbances, the physical ambient and opera-
tional conditions at the place where the product is installed,
must meet the provisions laid down in the paragraph "Electro-
magnetic Compatibility (EMC)" of DIN EN 60204-1.
5. Operating principle and settings
5.1 LED functions
ON: Status operating voltage (LED is on,
when the operating voltage on the terminals is ON)
A: channel A (on, when frequency at channel A)
B: channel B (on, when frequency at channel B)
OUT: enabling signal (on when 13-14, 23-24, 33-34 closed)
ERR: error (on in case of malfunction)
