7.3 Electrical connection
(USA/CANADA Version only)
DANGER
Risk of strong damages and fire on the
electric power components.
•
The power supply to the compressor
side has to be fitted for industrial
equipment and fulfilling the
requirements of NFPA 79. Any kind of
operation outside of the stated limits of
NFPA 79 is inadmissible.
•
The electrical connection should be
made by a qualified electrician.
DANGER
Only for L30RS-L45RS: 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.
WARNING
If local regulations are stricter than the
values given below, observe the stricter
regulations.
WARNING
If the electrical connection is made to a
non-earthed three-phase system (IT
network), please see the corresponding
notes in the included frequency converter
documentation.
If a residual current device (RCD) is used to
monitor the earthing connection in the
system for earth faults, to prevent
interruptions only Type B devices
(adjustable trip setting and delay) may be
used.
To establish an electrical connection, proceed as
follows:
Route the supply cable (-1 - Fig. 13) through the cable
gland on the switch cabinet and tighten screws.
Connect the supply line to the connecting terminals as
shown in the circuit diagram.
