2 - INSTALLATION
1. CN1:
There are 3 different ways to feed voltage to the LGL box:
− 18Vac to 28Vac.Single-phase alternating voltage
Connect the two (single-phase) lines between two phases whatsoever
(1, 2 or 3) of the CN1 connector.
18Vac to 28Vac three-phase alternating voltage.
Connect the three (three-phase) lines into the 3 phases (1, 2 and 3) of
connector CN1.
− 23Vdc (*) to 40Vdc Direct voltage.
Connect the 2 (dc power supply) lines between 2 phases whatsoever
(a, b or c) of the POWER connector.
Connect the earth-fault protection cable into the clamp marked with
the electrical earth symbol.
(*) N.b.: The minimum power supply voltage of the box is 23Vdc, 1V
higher than that of the devices to compensate for the voltage drop on
external diodes.
2. Connectors for single cable. Available for up to 4 accumulators.
The position will automatically assign the address to the device.
J1 = ID 1, J2 = ID 2... J4 = ID 4.
