NOTICE
Wrong connected voltage!
Incorrect supply voltages can lead to component damage.
Compare the supply voltage value with the voltage specification stated on the
nameplate at the device. Set up the necessary fuse protection in accordance
with the “Technical Data” section or the circuit diagram.
Loose bolts and terminal clamping points!
During transport and installation, screws and terminal clamping points might get
loose.
Check all screws and terminal clamping points in the control cabinet for secure
fitting prior to setting up the unit.
Danger of damage to unit components due to incorrect rotating field!
Even short-term operation of the unit with an incorrect rotating field can lead to
considerable damage to the unit components, especially to the Scroll
compressors (if installed).
Check the electrical rotating field of the power supply connection for correctness
prior to setting up the unit.
There is no warranty for damages caused by operating the unit with an incorrect
rotating field.
NOTICE
Impairment of the unit operation!
EMC disturbance may affect the unit function negatively and/or damage
components in case of insufficient equipotential bonding.
•
If devices/machines are electrically coupled, additional local equipotential
bonding must be provided between the devices/machines.
•
Connect a suitable equipotential bonding cable to the marked location in
the unit.
•
Connect any conductive pipes to the equipotential bonding system.
NOTE
Ensure clockwise phase rotation.
