Electrical connection
(only USA/CANADA version)
DANGER
Risk of strong damage 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 L23RS-L29RS: 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.
Make electrical connections as follows:
Feed the supply cable through the opening (-M50- Fig. 13)
in the switch cabinet and screw tight.
Connect the supply cable to the connection terminal
following the circuit diagram.
