Electrical installation
⚠
CAUTION
•
All electrical connections to the machine must be carried out in compliance with
laws and regulations in force.
•
All installation, operating and maintenance activities must be carried out by
qualified personnel.
•
Please refer to the specific wiring diagram for the machine that you have
purchased, and which was sent with the unit.
•
Should the wiring diagram not come with the machine, please contact your dealer
for further action.
•
Use copper conductors only. Failure to use copper conductors could cause
overheating or corrosion at the connection points and damages the unit.
•
To avoid interference, all control wires must be installed separately from the
power wires. Use separate electrical conduits for this purpose.
•
Before servicing the machine in any way, open the general disconnecting switch
on the machine's main power supply.
•
When the machine is off, but the disconnector switch is in the closed position,
unused circuits are live as well.
•
Never open the terminal board box of the compressors before having opened the
unit's general disconnecting switch.
•
In installations with power supply lines longer than 50 meters, inductive coupling
between phases and between phase and earth generates significant
electromagnetic field.
•
In order to limit these phenomena, it is good practice to lay out the phase wires
symmetrically, as described in the figure:
•
Chiller unit compressors are single-direction rotation compressors and can be damaged if
rotated in the wrong direction. For this reason, proper phasing of electrical power is
important. Terminal block indicator (R, S, T). R=L1, S=L2, T=L3
