Electrical Connections - Beretta POWER MAX 50 P DEP 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 com-
ponents.
b
The following is mandatory:
- The use of an omnipolar magnetothermic switch,
line disconnecting 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 sup-
ply conductors
- Use cables with a section greater than or equal to 1.5
mm , complete with cable terminal caps
2
- Refer to the wiring diagrams in this manual for all
electric operations.
b
The use of adaptors, multiple sockets and extensions
to power the appliance is not allowed
b
to connect external electric components, it is neces-
sary 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 always guarantee their correct positioning
within the appliance.
b
Electrical supply cables and control cables (room/
heat demand thermostat, external temperature
probes, etc.) must be strictly separate the one from
the other and fitting inside independent ribbed PVC
sheaths up to the electrical panel.
b
The connection to the electrical power supply must
be performed using type 1 sheathed cables (3 x
1,5) N1VVK or equivalent, while simple N07VK type
or equivalent conductors can be used for the ther-
moregulation and low voltage circuits.
b
If the electrical power provided by the electrical com-
pany is of " PHASE-PHASE " connection type, preven-
tively contact the nearest Technical Assistance Cen-
tre.
b
Never shut the appliance off during normal operation
(with the burner on) by shutting off the electrical pow-
er supply using the On-Off key or an external switch.
This could cause the primary heat exchanger to over-
heat.
b
To switch it off (during the heating stage) use a room/
heat demand thermostat. The On-Off key can only be
actioned whist the appliance is in stand-by or emer-
gency mode.
b
Before connecting any external electrical compo-
nents 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, ac-
celeration current).
b
Temperature probes must be NTC like. For resist-
ance value, refer to table pag 12
b
Always check the proper operation of the "grounding
conductor" for the electrical system to which the ap-
pliance will be connected.
b
shall bear no responsibility for any personal
B
injuries or property damage caused by non-com-
pliance with wiring diagrams or the electrical sys-
tem's incorrect/lacking connection to the grounding
system, or by non-compliance with applicable 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 de-
mand 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 elements (rain, sun, wind, etc.) unless it is
equipped with the relevant weatherproof kit.
a
It is prohibited to pull, detach, or twist any electric ca-
bles coming from the thermal module even when the
latter is disconnected 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)
