Connection and operating information
Preliminary checks
The connection must be carried out in compliance with the current safety stand-
ards. To ensure a correct operation of the unit, please strictly follow these rec-
ommendations:
- the input powering has to be:
400V version: 360-460V, 50/60Hz plus ground, withstanding a current of 11A per
phase
208V version: 187-230V, 50/60Hz plus ground, withstanding a current of 15A per
phase
- the earth installation must comply with current standards
- the cables to be connected to the output terminals must have a size suitable to the
lamp power.
During connection pay attention to the lamp polarity.
Important note: the ground connection of the power supply must be equipotential
with respect to the ground connection of the lamphouse. To do this, perform a
connection between the ground (PE) of the power supply and the ground of the
lamphouse (cable length: 400 mm max.).
Connecting input/output cables
Connect the input/output cables to the relevant terminal board.
Pay attention to lamp polarity and terminal identification:
