6.2 Connection to mains power
The unit can operate with voltage
380÷420 Vac
three phase with neutral
(GR0402)
or with voltage
210÷250 Vac
three phase
(GR0399)
and with frequency of
50/60Hz
.
A.
Connect the projector to the ballast unit.
Connect the cable
“7”
into the socket
“8”
.
B.
Connect the socket (3P+N+G) supplied with the unit, to
a cable with a minimum section of 2.5 mm²
(3x2.5 + N +G).
If the power supply voltage is
210÷250 Vac
, do not
connect the neutral.
C.
Insert the plug in the relevant socket
“9”
of the ballast
unit and power up the unit.
Before connecting the unit, verify that power supplies
features are compatible with
380÷420Vac 50/60Hz + N Ground (GR0402)
210÷250Vac 50/60Hz + Ground (GR0399)
The power supply line must be protected by appropriate
grounding and the use of a magnetothermic differential
switch along the power supply line with the following
electrical characteristics:
nominal current (In) 25A
sensitivity (Id) 0,03A.

Warning!
• Before connecting the unit, verify that power supplies features are compatible with the unit features.
• The unit must never be installed if not grounded electrically.
• It is suggested to use a magnetothermic switch along the power supply line, as prescribed by in force rules.
• The unit must not be powered up through a dimmer power device.
• Wiring and connection actions are to be performed by a qualified staff.
