in pressure that is too high, breaking open
parts of the system and causing serious or
fatal injury.
Never operate a screw compressor system
with a defective pressure relief valve or
without pressure relief valve!
10.9 Connecting terminals in the switch
cabinet
DANGER
High voltage – Hazard of shock, burns, or
death
 Only qualified electricians may work on
the control cabinet.
 Only perform checks and carry out work
on the screw compressor when the unit
is out of operation, depressurized, and
secured from being switched on again!
 Push the STOP button on the
compressor controller. After the soft-
stop time (30 sec.), set the on-site main
switch to "0"(OFF) and secure it against
being switched on.
DANGER
Only for L90RS-L132RS: There is a risk of
electric shock from charged capacitors!
 Disconnect the system from the mains
and wait 10 minutes before touching
electrical components. The power
capacitors need this time to discharge.
The connecting terminals in the switch cabinet have to
be checked and, if required, re-tightened during first
commissioning and afterward according to the
maintenance schedule.
