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.
