WARNING
▪
If the power supply has a missing or wrong N-phase, equipment might break
down.
▪
Establish proper earthing. Do NOT earth the unit to a utility pipe, surge absorber,
or telephone earth. Incomplete earthing may cause electrical shocks.
▪
Install the required fuses or circuit breakers.
▪
Secure the electrical wiring with cable ties so that the cables do NOT come in
contact with sharp edges or piping, particularly on the high-pressure side.
▪
Do NOT use taped wires, extension cords, or connections from a star system.
They can cause overheating, electrical shocks or fire.
▪
Do NOT install a phase advancing capacitor, because this unit is equipped with an
inverter. A phase advancing capacitor will reduce performance and may cause
accidents.
WARNING
▪
All wiring MUST be performed by an authorised electrician and MUST comply
with the national wiring regulation.
▪
Make electrical connections to the fixed wiring.
▪
All components procured on-site and all electrical construction MUST comply
with the applicable legislation.
WARNING
ALWAYS use multicore cable for power supply cables.
