Preparing For Assembly - Varta element 3 Instruction Manual

The current sensor is designed for top hat rail mounting and for a
maximum current of 50 A per phase. For installation, the sensor
board points towards the sub-distributor. For installation direction,
see also Figure 12.
Phases L1, L2, L3 must be identical for building connection,
current sensor and terminal block. This means, phase L1 of the
building connection leads through opening L1 of the current
sensor to terminal L1 on the terminal block in the storage cabinet.
Connect the current sensor supplied with the sensor cable to the
energy storage system. See the current measurement socket in
Figure 14.
For the connection arrangement, see figures 1a/1b and 2a/2b
in the attachment.
