` Ensure that the plug terminator is
inserted at the side of the unit.
Connect base unit and PNOZsigma
contact expander module:
120 (4.72")
` Remove the plug terminator at the
side of the base unit and at the con-
tact expander module.
` Connect the base unit and the con-
tact expander module to the sup-
plied connector before mounting
the units to the DIN rail.
Installation in control cabinet 98 (3.86")
17,5
` The safety relay should be installed * 102 (4.02") (0.69")
in a control cabinet with a protec-
tion type of at least IP54.
` Use the notch on the rear of the unit
to attach it to a DIN rail.
` Ensure the unit is mounted securely
on a vertical DIN rail (35 mm) by us-
ing a fixing element (e.g. retaining
bracket or an end angle).
` Push the unit upwards or down-
wards before lifting it from the DIN
rail.
