Connecting The Chiller Line; Electrical Connection - Immergas MAGIS PRO 12 V2 Instructions And Recommendations

1.8

CONNECTING THE CHILLER LINE

As far as connecting the cooling line is concerned, all the instructions contained in the outdoor unit instructions booklet must be fol-
lowed.
Make the connections directly on the indoor unit couplings, or use the rear outlet kit (optional).

ELECTRICAL CONNECTION

The internal unit 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.
The manufacturer declines any responsibility for damage or physical injury caused by failure to connect the indoor unit to an
efficient earthing system or failure to comply with the IEC reference standards.
Connection cables must respect the prearranged routes.
Use 3 clips (c) (not supplied) to group the individual cables (max. 1.5 mm
Use the specific fairleads (d) on the left side, making sure to put at most 2 multi-polar cables (max 3 x 1 mm
The figure 7 shows cables in a hypothetical connection. To make the connections based on your own requirements, see the instructions
below.
Open the control panel connections compartment
Fig. 7.
To carry out electrical connections, all you have to do is open the connections compartment as follows.
1. Remove the front panel.
2. Disassemble the cover.
3. Loosen the screws (a).
4. Remove the cover (b) from the control panel (c).
At this point, you can access the terminal board.
Also ensure that the electrical installation corresponds to maximum absorbed power specifications as shown on the indoor unit da-
ta-plate.
Indoor units are supplied complete with a "Y" type power supply cable H 05 VVF 3 x 0,75 mm
The power supply cable must be connected to a 230V ±10% / 50Hz mains supply respecting L-N
polarity and earth connection; this network must also have a multi-pole circuit breaker with
class III overvoltage category in compliance with installation regulations.
To protect from possible dispersions of DC voltage, it is necessary to provide a type A differen-
tial safety device.
If the power cable is damaged, contact a qualified company (e.g. the Authorised Technical As-
sistance Centre) for its replacement to avoid a hazard.
The power cable must be laid as shown (Fig. 7).
If the fuses on the circuit boards need to be replaced, this must also be done by qualified personnel: use a F3.15A H250V fuse on the P.C.B.
For the main power supply to the appliance, never use adapters, multiple sockets or extension leads.
Make the various electrical connections according to your needs (Fig. 8, 9):
Outdoor unit electrical connection
The indoor unit must be coupled to an outdoor unit by connecting terminals F1 and F2 as shown in the wiring diagram (Fig. 9). The in-
door unit is powered at 230 V, regardless of the outdoor unit.
Configure the indoor unit parameters as indicated in paragraph Parag. 3.9.
Photovoltaic system installation
Connecting the product to a photovoltaic system enhances use of the outdoor unit when the photovoltaic panels are operating. Carry out
the connection as indicated (Fig. 8).
