Figure 34 - Connecting the batteries
1. Connect the connection wire [A] to the two batteries.
2. Connect the wire [B] to the batteries.
Attention:
Be sure that cable polarity is correct.
3. Connect the terminal [C] of the battery wire to the proper connector of the power-supply unit (
Figure 7
- Switching power supply, [C]
).
Attention:
Be sure that connector polarity is correct.
The batteries are the secondary power supply of the system. Once powered up, the panel will charge and
monitor the batteries automatically. The battery monitoring process is as follows:
• Efficiency test
The control panel tests the battery efficiency every 10 minutes. If their internal resistance is over the
allowed limit, the control panel will signal a “
Missing bat.
” fault.
• Battery level test
The control panel monitors the charge level of the batteries continuously. In the event of mains failure,
the control panel will continue monitoring the charge level of the batteries. If the voltage drops below
22.8V, the power supply station will signal a “
Battery low
” event. The event will end when the voltage
restores to 24.6V.
• Deep discharge shutdown
If a mains failure event lasts for a long period, and battery voltage drops below 18V, the panel will shutdown
the batteries automatically in order to avoid irreparable damage.
6.17 Thermal probe
Attention:
In order to validate the IMQ-SISTEMI DI SICUREZZA certification and comply with EN 54-4
requirements, installation of a thermal probe is essential.
The thermal probe regulates the charging process in accordance with the battery temperature. The thermal
probe protects against battery overheating and their consequent permanent damage.
6.17.1 Connecting the thermal probe
Connect the thermal probe to the proper connector of the power-supply module (
Figure 7 - Switching
power supply, [D]
and
Figure 34 - Connecting the batteries
,
[D]
).
Using adhesive-insulating tape, attach the thermal probe to one of the batteries, in order to provide
optimized heat-transfer measurements.
