Electrical Connection; Remote Controls And Room Chrono-Thermostats (Optional) - Immergas Victrix Tera 28 1 Instructions And Warnings

1.9

ELECTRICAL CONNECTION.

The appliance has an IPX5D protection degree; electrical safety of
the appliance is achieved only when it is connected properly to an
efficient earthing system, as specified by current safety standards.
ATTENTION:
the manufacturer declines any respon-
sibility for damage or physical injury
caused by failure to connect the boiler
to an efficient earthing system or failure
to comply with the reference standards.
• Open the control panel connections compartment (Fig. 8).
To carry out electrical connections, all you have to do is open the
connections compartment as follows:
- Disassemble the cover (Fig. 54).
- Disassemble the cover (b) as follows:
1. Loosen the screw (a).
2. Press the two hooks on the connections compartment
cover.
3. Remove the cover (b) from the control panel (c).
- At this point, it is possible to access the terminal board (d).
Also ensure that the electrical installation corresponds to maxi-
mum absorbed power specifications, as shown on the boiler data
nameplate. Boilers are supplied with a special "X" type power
cable without plug.
ATTENTION:
the power supply cable must be connect-
ed to a 230V ±10% / 50Hz mains supply
respecting L-N polarity and earth con-
nection ; 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 differential safety device.
If the power cable is damaged, contact a qualified company (e.g.
the Authorised After-Sales Technical Assistance Service) for its
replacement to avoid a hazard.
The power cable must be laid as shown (Fig. 7).
If the network fuse on the P.C.B. needs replacing, this must also
be done by qualified personnel: use a 3.15 A fast fuse.
For the main power supply to the appliance, never use adapters,
multiple sockets or extension leads.
Installation with system operating at direct low temperature.
The boiler can directly supply a low-temperature system by setting
the flow temperature adjustment range "t0" and "t1" (Par. 3.11).
In this situation it is good practice to insert a relevant safety kit
(optional) made up from a thermostat (with adjustable tempera-
ture). The thermostat must be positioned on the system flow pipe
at a distance of at least 2 metres from the boiler.
1.10 REMOTE CONTROLS AND ROOM CHRONO-
THERMOSTATS (OPTIONAL).
The boiler is prepared for the application of room chrono-ther-
mostats or remote controls, which are available as optional kits
(Fig. 9).
All Immergas chrono-thermostats are connected with 2 wires
only. Carefully read the user and assembly instructions contained
in the accessory kit.
ATTENTION:
disconnect power to the appliance be-
fore any electrical connection.
