Connecting the VI15x Voltage Module
The modules VI150-FBP.0 and VI155-FBP.0 allows to measure the motor supply voltage, cosphi (power factor) and to calculate
thereof the active power and other values.
There are two module variants. The VI155 module can be used in grounded (TN) and ungrounded
(IT) networks.
The VI150 module can only be used in grounded networks (TN).
When using a voltage module the phase order at the UMC must be L1 to L3 from left to right looking from top.
In single phase operation mode connect N->L1 and L->L2
Note that the connection cables for voltage measurement (terminals marked with L1, L2, L3) may require additional
cable protection
Don't connect any cable to the VI1xx terminals marked with NC (not connected)
Note that a distance of 10 mm left from the terminal L1 and right from the terminal L3 to the next device might be
required for voltages >230 V AC or > 400 V AC respectively depending on the equipment mounted left and right of
the module.
The module is connected via terminals Ca and Cb (see below) to the UMC100.3.
It is possible to mount the module separately from the UMC100.3.
Connection cable:
UMCIO-CAB.030CAB

Connection between UMC100.3 and voltage module
Wiring is shown for module VI150. It is
the same for VI155.
