Installation
Install base unit without contact expansion module:
} Ensure that the plug terminator is inserted at the side of the unit.
Connect base unit and PNOZsigma contact expansion module:
} Remove the plug terminator at the side of the base unit and at the contact expansion
module.
} Connect the base unit and the contact expansion module to the supplied connector be-
fore mounting the units to the DIN rail.
Installation in control cabinet
} The safety relay should be installed in a control cabinet with a protection type of at least
IP54.
} Use the notch on the rear of the unit to attach it to a DIN rail (35mm).
} When installed vertically: Secure the unit by using a fixing element (e.g. retaining
bracket or end angle).
} Push the device upwards or downwards before lifting it from the DIN rail.
