Note:
The end of a stranded wire must not be
consolidated with soft soldering in points where
the wire is subjected to contact pressure.
2. Crimp the earth line wire to the eyelet terminal [B].
3. Attach the wire with the eyelet to the control panel using the
ground connection screw [C].
4. Ensure that the terminal "
[D]], the motherboard [E] and the frontplate
[F]. of the cabinet are connected to earth system.
Attention:
The protective earthing system must be compliant with the local safety regulations, fire codes, laws
and bylaws in force.
Note:
A protective earth connection ensures that all exposed conductive surfaces are at the same electrical
potential as the earth surface, in order to avoid the risk of electrical shock if a person touches a device in
which an insulation fault has occurred. In the event of an insulation fault, a protective earth connection
will generate a high fault current which in turn will trigger an overcurrent protection device (fuse) and
disconnect the power supply.
5. Ensure that low-current safety or signal lines DO NOT come into contact with points with potentially dangerous
currents.
Using a plastic cable tie, bunch the wires together and secure them to one of the wire hooks on the back of the
cabinet
[G].
Note:
The connection wires (to the mains supply and also any other wires inside the cabinet) must be secured
to the cable hooks on the backplate by means of plastic cable ties. Use cable with double isolation for
the connection to the electrical mains.
3.3.2 Connecting the batteries
The metal cabinet of the control panel provides housing for two 12V, 7 Ah lead batteries for the small version and 17 Ah
for the large version. The two batteries must be connected in series, in such way as to supply 24V.
1. Place the batteries into the battery compartment inside the cabinet (paragraph 2.2 - [Z]).
2. Using the battery wire ([A]), connect the batteries together.
3. Connect the wire coming from the power supply ([B] paragraph 2.2 - [T]) to the battery terminals ([C]).
Attention:
Ensure that the polarity is correct.
Red - positive
Black - negative
Connection of the batteries before the mains voltage is present will not activate the system. Once the mains voltage is
supplied, the power-supply module will connect the batteries automatically and initialize the circuits which manage
them.
4. Position the thermal probe (paragraph 2.2 - [U]).
The thermal probe must be positioned on the side of the battery and held in place by a strip of tape ([D]).
