DANGER
Exposure to high pressure or toxic
liquids
Death or serious personal injury
‐
Failure to remove the
jumper disables the STO
function, and the motor might not
stop as intended, and can cause
severe injury or death.
‐
Failure to use safety-monitoring
relay compliant with Category 3/
PL d according to ISO 13849-1 or
SIL 2 according to EN 62061 and
IEC 61508 can cause death or
serious personal injury. Perform a
functional test every 12 months to
ensure that the system works
properly.

Short-circuit protected cable if the product is not
installed inside an IP54 cabinet.
Connecting the signal terminals
As a precaution, signal cables must be
separated from other cable groups by
reinforced insulation in their entire
lengths.
Connect the signal cables according to the guidelines for good
practice to ensure EMC-correct installation.
• Use screened signal cables with a cable cross-section of
minimum 0.5 mm
2
and maximum 1.5 mm
2
.
• Use a 3-conductor screened bus cable in new systems.
Connection of a thermistor (PTC) to CUE
A PELV circuit provides protection against electric shock. Special
connection requirements apply to this type of circuit. The
requirements are described in EN 61800-5-1.
