2.5 Safety classification
Standards:
EN ISO 13849-1, IEC 61508, EN 60947-5-1
PL:
STOP 0: up to e, STOP 1: up to d
Category:
STOP 0: up to 4, STOP 1: up to 3
PFH value:
STOP 0: ≤ 2.0 x 10

/h,
STOP 1: ≤ 2.0 x 10
-7
/h
DC:
STOP 0: 99% (high),
STOP 1: > 60% (low)
CCF:

20 years
The PFH values of 2.0 x 10
-8
/h and 2.0 × 10
-7
/h applies to the combina-
tions 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-menti-
oned 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 up until it latches in position.

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
operational conditions at the place where the product is ins-
talled, must meet the provisions laid down in the paragraph
"Electromagnetic Compatibility (EMC)" of DIN EN 60204-1.
