13. Electrical Connections
WARNING!
It is absolutely necessary, before making any connections, to use a suitable tester to
check the supply voltage. This must be the same as the voltage indicated on the technical
data plate.
The user must furnish and install, upstream from the unit, an isolating switch with a pre-
fuse and capacity as specified on the technical plate in order to be able to perform
maintenance on the unit in the absence of electricity.
•
Check the supply voltage and frequency;
•
Check that supply voltage and frequency are compatible with those for the unit.
•
Interrupt both main power and auxiliary power before working on the system;
•
Select connection cables (not supplied) according to EN60204-1 Standards
•
On the main power supply lines, in preference install an omni-pole automatic switch, curve type
C, eventually complete of another differential switch. Alternatively, besides the isolating omni-
pole switch, install a safety fuse, retarded, aM type;
•
Check that power cables are installed with a sufficient distance from alarm cables.
•
Check that the supply voltage of the cooling unit is disconnected when opening the cabinet
doors.
•
To connect power supply, use cables with section suitable to the power absorbed by the users.
These cables must be compliant with current standards.
ATTENTION!
The inobservance of these instructions might provoke damages or malfunction of components and
the warranty shall become forthwith void.
