Electric Connection - Immergas MAGIS PRO ERP Instruction And Recommendation Booklet

1.7 ELECTRIC CONNECTION.

The appliance has an IPX4D degree of protection;
electrical safety of the appliance is achieved only
when it is properly connected to an efficient
earthing system, as specified by current safety
standards.
Attention: Immergas S.p.A. declines any respon-
sibility for damage or physical injury caused by
failure to connect the hydronic module to an
efficient earthing system or failure to comply
with the reference standards.
- Connection cables must respect the prear-
ranged routes. Use 3 clips (c) (not supplied)
to group the individual cables (max. 1.5 mm
into the lower terminal board. Use the specific
fairleads (d) on the left side, making sure to put
at most 2 multi-polar cables (max 3 x 1 mm
in each fairlead.
As an example, figure 1-5 shows cables in a
hypothetical connection. To make the connec-
tions based on your own requirements, see the
instructions below.
• Open the control panel connections compart-
ment (Fig. 1-5).
To carry out electrical connections, all you have
to do is open the connections compartment as
follows.
- Remove the front panel (Fig. 3-5b).
- Remove the cover (b fig. 1-4).
1) Loosen the screws (a).
2) Remove the cover (b) from the control
panel (c).
- At this point, you can access the terminal board.
Also ensure that the electrical installation corre-
sponds to the maximum absorbed power speci-
