Mounting Procedure for PM891 Unit Before mounting any processor unit or communication interface on the DIN-rail, read carefully the installation instructions provided with the equipment. To mount the PM891 unit on the DIN-rail, a blade screwdriver that fits securely into the unit locking screw (1 mm slot) is required. For details about the unit locking screw, see Figure 20 on page 71. To mount the PM891 unit on the DIN-rail: 1. Rotate the locking device to the OPEN position (1), hook the upper lip at the rear of the unit securely over the upper edge of the DIN-rail, and gently snap the unit fully into the mounting position. 2. Rotate the locking device to the SLIDE position (2), slide the unit along the DIN-rail to the desired mounting position, and using the connector plugs and sockets gently attach it to the adjacent unit baseplate. Figure 19. AC 800M Controller (except PM891) – Side View To prevent damage to the pins, ensure that the baseplate plugs and sockets are fully aligned as the units interconnect. Do not apply excessive force.

When the interconnection is complete, rotate the locking device clockwise to the LOCKED position (3). The PM891 unit is now fully locked into the position and has a good ground connection to the DIN-rail. It is essential that the locking device be placed in the LOCKED position to avoid possible problems caused by vibration and/or intermittent grounding.

AC 800M units must be disconnected from the power source before removing them from a DIN-rail! It is not allowed to manipulate CEX bus baseplates in a powered and running system. Before changing or removing a baseplate, all CEX modules on that segment must be removed.
