6.1 Connection requirements
Consider the minimum distance to adjacent devices:
lateral 0 mm, top 20 mm, bottom 20 mm.
Only
qualified personnel
are permitted to carry out the work necessary
to install, commission and run a device or system.
Risk of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
• An electric shock
• Damage to the electrical installation
• Destruction of the device
Before installing and connecting the device, make sure
that the
in-
stallation
has been
de-energised
. Observe the rules for working on elec-
trical installations.
Risk of electric shock!
Nominal voltages up to 1000 V may be present on the terminals L1/+ to
L3/- which can be lethal. Make sure the terminal covers are properly
mounted and clicked in before putting the device into operation.
Risk of electric shock!
High voltage is applied at the terminals, which in case of direct contact
can be life-threatening. If the terminals L1/+, L2, L3/- of the device are con-
nected to a live IT system, the terminals E and KE must not be disconnected
from the protective conductor (PE).
Warning of insulation monitoring devices that do not work correctly!
Connect the terminals KE and E individually to the protective earth con-
ductor PE.
