Securing handle

The front panel of the protection relay has an integrated sealing screw. By default, the
screw is screwed all the way in and not used when installing or detaching the plug-in
unit. Instead of sealing the plug-in unit, the sealing screw and the spacer supplied with
the protection relay can be used for securing the handle in place.
1. Fully open the sealing screw and remove it.
2. Re-insert the sealing screw with the spacer.
