Mounting and connection
Ensure disconnection from the IT system!
When insulation or voltage tests are to be carried out, the device must
be isolated from the system for the test period. Otherwise the device
may be damaged.
Check proper connection!
Prior to commissioning of the installation, check that the device has
been properly connected and check the device functions. Perform a
functional test using an earth fault via a suitable resistance.
Pluggable push-wire terminals
All terminals are pluggable push-wire terminals. Solid connecting
wires can be directly plugged in. For connection of flexible cables, the
push-wire terminals must be pushed open by pressing the
corresponding orange interlocking mechanism with a flat-head
screwdriver.
