Attention

:strong:Risk of malfunctions!

Unused slots for communication modules are not protected against accidental physical contact.

  • Unused slots for communication modules must be covered with dummy communication modules (TA524 TA524 - Dummy Communication Module to achieve IP20 rating.
  • I/O bus connectors must not be touched during operation.

Attention

Only use TA543 accessory when the PLC is to be screw mounted. With DIN rail mounting the PLC could not be removed from the rail without the risk of damaging the housing.

Mounting with Screws

If the Processor Module should be mounted with screws, Screw Mounting Accessories TA543 TA543 - Screw Mounting Accessory must be inserted at the rear side first. These plastic parts prevent bending of the Processor Module while screwing on. 3x TA543 Screw Mounting Accessories are needed per PM595. A dimension drawing for the position of screw’s holes can be found in Mechanical Dimensions AC500 Mechanical Dimensions AC500.

  1. Snap 3x TA543 Screw Mounting Accessories to the positions marked in the picture.

  2. Fasten the Processor Module with 4 screws (diameter 4 mm max.)

Note

By wall mounting, the Processor Module PM595 is earthed through the screws. It is necessary that

  • the screws have a conductive surface (e.g. steel zinc-plated or brass nickel-plated)
  • the mounting plate is earthed
  • the screws have a good electrical contact to the mounting plate
