3.2.1 Mounting a sealable shroud
To prevent changes from being made to the overload setting, you can install
a ZB-XPLH/XTOBXCOV sealable shroud (accessories) and seal it with sealing
wire. This will reduce the risk of tampering and improve operational safety
and reliability.
Overload relays in enclosures or behind covers can be conveniently operated
by using M22-DZ… pushbuttons.
