Mains:
Use a bipolar D curve circuit breaker (4A for 24V version and 6A for 48V version) to connect the
power supply to the mains circuit.
Batteries:
The battery temperature sensor must be placed as close to the battery as possible but doesn't
need to be in contact with it. For example, it may be fixed on the battery cables by mean of the
two tire wraps fitted.
Battery wiring instructions:
Use a bipolar isolating switch (e.g. isolator or disconnecting switch) by connecting the batteries
to the supply.
An additional fuse is also recommended to protect this circuit.
In order to avoid any electrical damage, the cables connecting the batteries must imperatively
match with the supply configuration (100 or 150A) : maximum sheath temperature, cross
section, allowed current, maximum voltage.
Operation:
The power supply takes a resistance measurement of the battery including connections every 4
hours.
The trigger threshold of the fault is 13 mW±10 % in 24V and 26mW±10% in 48V if the jumper is
set on '75', and becomes 20mW±10% in 24V and 40mW±10% for 48V if the jumper is set on
'50'.
Exceeding this threshold is signalled as a battery fault and means that the power supply with its
associated battery will not have the required back-up duration in case of mains power cut.
To avoid initiating this fault, please take notice of the following elements:
o Use authorized batteries.
o Do not exceed the lengths of the table.
