Electrical installation
Contents of this chapter
This chapter describes the wiring of the safety option done at the factory and contains
guidelines for making user connections (if any).
Wiring
The operating switch and the indication lamp for the POUS function are not factory-installed.
The user must install and wire them to the inverter units on site.
There is an extension terminal block [X68] for the connections to the FSO module inside
the inverter unit cabinet. This terminal block is the user interface. The FSO module connectors
[X113] and [X114] have been wired to [X68]. The tables below show the connections between
the extension terminal block and the FSO module.

ABB installs the FSO modules and the wirings between the FSO modules and the inverter
units and user interface at the factory. The FSO module has double terminals for the
connection of the POUS switch. Wire the POUS switch to the terminals according to the
circuit diagrams of the delivery. Obey these general rules:
1.
Use only double-contact switches. We recommend approved and lockable switches.
2.
Connect the switch with two conductors (two-channel connection).
