5 Mounting
☐ In order to mount the Cluster Controller, the top-hat rail must be at least 26 cm long. When a
top-hat rail power supply unit is used, the top-hat rail must be correspondingly longer.
☐ The top-hat rail must be securely mounted on the wall or in the switch cabinet.
Procedure:
• Use the rear-side upper retainers to hook the
Cluster Controller into the upper edge of the top-
hat rail and press down toward the top-hat rail.
This will hook the spring-mounted top-hat rail
locking mechanism on the Cluster Controller
onto the lower edge of the top-hat rail.
☑ The top-hat rail locking mechanism snaps into place.
