Safety
Intended use
Ä
Do not open the control unit
Never open, tamper with or attempt to modify the control unit.
Ä
Observe protection class
Only use the control unit in spaces with a minimum protection class of IP54 (e.g.
a switch cabinet).
The control unit is designed for processing the signals of a pressure-sensitive protec-
tive device (PSPD). It evaluates the output signals of BK-type sensors. The integrated
output signal switching devices (OSSD) transmit the evaluated safety signals directly
to the downstream control.
The product complies with ISO 13849-1:2015 category 3 PL e. To prevent any reduc-
tion in the safety classification, the downstream control must be of the same catego-
ry or higher.
