Electrical Connections - Beretta POWER MAX Installation And Operation Manual

2.14 Electrical connections

The thermal module POWER MAX is manufactured fully wired and
only needs to be connected to the mains, the room/heat demand
thermostat and any other system components.
b
The following is mandatory:
- The use of an omnipolar magnetothermic switch, line discon-
necting switch in compliance with CEI-EN standards (contact
opening of at least 3 mm)
- Respect the connection L (line) - N (neutral). Keep the earth
conductor 2 cm longer than the power supply conductors
- Use cables with a section greater than or equal to 1.5 mm
complete with cable terminal caps
- Refer to the wiring diagrams in this manual for all electric op-
erations.
b
The use of adaptors, multiple sockets and extensions to power
the appliance is not allowed
b
to connect external electric components, it is necessary to use
auxiliary relays and/or contactors to be fitted in a dedicated
external electrical panel
b
Any work on the electrical system must be carried out only by
qualified personnel in compliance with all legal provision and
safety regulations in particular
b
Secure the cables into the dedicated cable ties in order to al-
ways guarantee their correct positioning within the appliance.
b
Electrical supply cables and control cables (room/heat de-
mand thermostat, external temperature probes, etc.) must be
strictly separate the one from the other and fitting inside inde-
pendent ribbed PVC sheaths up to the electrical panel.
b
The connection to the electrical power supply must be per-
formed using type 1 sheathed cables (3 x 1,5) N1VVK or equiv-
alent, while simple N07VK type or equivalent conductors can
be used for the thermoregulation and low voltage circuits.
b
If the electrical power provided by the electrical company is
of " PHASE-PHASE " connection type, preventively contact the
nearest Technical Assistance Centre.
b
Never shut the appliance off during normal operation (with the
burner on) by shutting off the electrical power supply using the
On-Off key or an external switch. This could cause the primary
heat exchanger to overheat.
b
To switch it off (during the heating stage) use a room/heat de-
mand thermostat. The On-Off key can only be actioned whist
the appliance is in stand-by or emergency mode.
b
Before connecting any external electrical components to the
appliance (regulators, electric valves, climate control probes,
etc.), check to make sure that their electrical characteristics
are compatible with the available inputs and outputs (voltage,
absorption, acceleration current).
b
Temperature probes must be NTC like. For resistance value,
refer to table pag 13
b
Always check the proper operation of the "grounding conduc-
tor" for the electrical system to which the appliance will be con-
nected.

shall bear no responsibility for any personal injuries or
B
property damage caused by non-compliance with wiring dia-
grams or the electrical system's incorrect/lacking connection
to the grounding system, or by non-compliance with applica-
ble CEI Standards.
a
It is strictly forbidden to use pipes of any kind to ground the
appliance.
a
It is prohibited to lay power supply and room/heat demand
thermostat cables near hot surfaces (delivery pipes). If they
may come into contact with parts that have a temperature of
over 50°C, use a suitable type of cable.
a
It is prohibited to touch electric appliances with damp/wet
body parts or when your feet are wet.
a
It is prohibited to leave the appliance exposed to weather ele-
ments (rain, sun, wind, etc.).
a
It is prohibited to pull, detach, or twist any electric cables com-
ing from the thermal module even when the latter is discon-
nected from the mains power supply.
Proceed as follows to access the control panel terminals:
- Remove the locking screws and the panel's front side
- Pull and slide the electrical panel's box towards the outside (1)
