8. INSTALLATION
In this section you will find all the information
necessary to electrically connect the MEC MIX series
generators.
8.1 HOW TO CONNECT THE GENERATOR TO
ELECTRIC LINE
- Electrical connections must be made from
professionally qualified staff. In each case, before
making electrical connections, make sure there is
no voltage in the cables.
1. Check that the supply voltage is 230V - 50Hz single
phase.
2. Make the electrical connection according to the
electrical assembly scheme using a cable type
H05 VVF 3x1.5 mm
2
with external diameter
maximum of 8.4 mm.
3. Make the electrical connection so that the ground
cable is longer than those under tension. It will be
the last cable to tear off in case it comes accidentally
pulled the power cord and a good continuity will
therefore be assured land.
- The electrical safety of the appliance is reached
only when the same is correctly connected
to an effective grounding system, performed as
required by current safety regulations. Do not use
the gas pipes as grounding Electrical devices.
4. The generator must be connected to the line
electrical supply by means of a switch bipolar with
minimum contact opening of 3 mm. The bipolar
switch is defined as the one with possibility of
opening both on the phase and on the neutral. This
means that at its opening both contacts are open.
- Control cables (in particular that of connection to
the chrono thermostat) must be protected by
interference created by power cables. This, ad
example, it can be obtained or by means of
shielding of cables or by laying in raceways
separate from those in which cables are used
power.
8.2 DIGITAL CHRONOTHERMOSTAT
INSTALLATION
- Electrical connections must be made from
professionally qualified staff. In each case, before
making electrical connections, make sure there is
no voltage in the cables For the installation of the
digital chrono thermostat proceed as follows:
1. Locate the location where you intend to install
the chrono thermostat trying to position it at approx
1.5 m from the floor, protected from drafts, direct
exposure to sun rays, influence from direct heating
sources (lamps, air flows of the appliance itself,
etc.) and possibly NOT on walls bordering the
outside, for not distort the detected temperature
and then the operation of the system.
YOU WILL AVOID SO STARTING AND NO
ARRESTS OF THE IMPLANT AND YOU WILL
GUARANTEE AN OPTIMAL COMFORT
ENVIRONMENT.
If this is not possible, screen the chrono thermostat
interposing a sheet of insulating material (cork,
polystyrene or other) between it and the wall.
2. Drill the wall at the points of fixing the chrono
thermostat.
3. Fasten the chrono thermostat with 2 expansion
screws.
4. The chrono thermostat is supplied already
connected to the electronic board of the generator
via a cable 5 meters long. For longer lengths at 5
meters use a 2-pole cable section 0.75 mm
2
with
maximum resistance per conductor (Use a shielded
cable if the installation has strong electrical
disturbances). In any case, the cable can not
be more than 30 meters long.
