ELECTRICAL CONNECTION
The entire connection of the device must take place
while the device is de-energized. The earthing
connection (by means of an M5x8 screw and a
notched stainless-steel washer) must take place
before any other connection is established.
On the device there are two terminals for the
protective earth connection, marked by the relative
symbols (IEC 60417 / BS EN 60417-1): one inside the casing and one outside, in proximity of the cable entry. The cross-sectional
2
area of the protective earth (PE) conductor must be the same as that of the phase conductor (S), with a maximum of 16mm .
Connect both earthing terminals to the equipotential line.
Before putting the device into service, make sure that the power supply voltage corresponds to the voltage indicated on the plate.
Protect the power and signal carrying cables with an overload protection element (rated current ≤ 10A).
A disconnect switch must be present near the device, to cut off power supply in the event of a fault. Utilize cables suitable for use
up to 90°C. The wiring diagram is located inside the lid.
