Figure 13 - Earthing system
2. Crimp the earth line wire to the eyelet terminal [B] (included in the package).
3. Attach the wire with the eyelet to the control panel using the ground connection screw [C].
4. Ensure that the terminal “
” of the power supply module [D], the motherboard [E] and the frontplate
[F] of the enclosure are connected to earthing system.
Danger:
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
backplate of the enclosure [G].
Note:
The connection wires (to the electrical mains, and also any other wires inside the cabinet) must be
secured to the cable hooks on the back box by means of plastic cable ties or similar fittings. Use cable
with double isolation for the connection to the electrical mains.
6. Insert the two 12V batteries and connect them to the power supply module (
Figure 9 - Switching power
supply, [C]
).

Connecting the batteries
The enclosure provides housing for two 12V lead batteries: 7 Ah for the SPS24060G model and 17 Ah for
the SPS24160G model. The two batteries must be connected in series, in such way as to provide a 24V
current.
Using the battery connection wire, connect the two batteries together then connect the batteries to the
power-supply module using the respective wire (included).
