1 Cable tree to periphery board or fire terminal board
2 Existing cable tree (connection for master power supply)
3 Additional cable tree for the second power supply (slave)
4 Additional fused terminal (F2) on the DIN rail
The connection lines marked in bold of the additional cable tree (3) and the
existing cable tree (2) must be wired again when installing the second power
supply (slave).
In order to avoid ambient temperature differences, the two power supply units
must be mounted next to each other in the same housing.
The batteries and the system supply must only be connected to the master
power supply unit.
The positive pole for the batteries must be re-wired on connection X8-9
(Master) and be provided with an external fuse.
Only one temperature sensor must be connected to the master power supply
unit.
The temperature sensor must be fitted close to the batteries. (You will find
precise details in document 008851).
