Risk of fatal injury from electric shock
If any of the supplies are switched on, some of the parts of the system which are
not yet fully installed may be live.

vice for manual mode selection and
wait until the display shows "Manual
mode".
Turn the Allen key to switch position
" "
Leave the transparent cover open and
lock the selector switch with padlock
to prevent it starting accidentally.
Risk of fatal injury from electric shock
Connecting wires can come loose and fall out if the ferrules being used are too
short, the wire ends are tinned or the connection screws have not been tightened
enough.
Consider a stripping length of 20 mm and do not use ferrules when connecting
Lines 1, 2 and 3.
Note the assignment of the terminals. Note especially that the two supplies are
always connected to the device from the top.
Use a torque wrench to tighten the terminal screws.
Check all the screws on a regular basis to make sure they are seated tightly.
Risk of destruction when insulation and voltage tests are carried out
-> Disconnect the device from the mains for the duration of the test.
Risk of destruction in the event of phase failure in three-phase systems
If only one of the phases fails, it may result in overvoltages on the other phases
which can damage the connected devices.
-> Install a device for all-pole disconnection in the event of phase failure.
Risk of destruction if connection incorrect
-> The terminals labelled GND must not be connected to PE.
