Assembly With Screws

If the Terminal Unit should be mounted with screws, a Wall Mounting Accessory TA526 Wall Mounting Accessory TA526 must be inserted at the rear side first. This plastic part prevents bending of the Terminal Unit while screwing on.

Fastening with screws of the Terminal Unit TU516 (as an example)

Note

By wall mounting, the Terminal Unit 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
