Customer interfaces for supplying power to an additional auxiliary power supply
system
This section describes only those interfaces in the cabinet that require additional connection
work by the customer. All other interfaces are pre-wired at the factory and are not designed
for customer connections. The table below provides an overview of the most important
technical data of the customer terminals in the cabinet.
Note
Additional information
All connections to be established on the plant side as well as the interfaces for integration
into the plant control system are described in the circuit and terminal diagrams on the
customer DVD supplied.

1)
The fuse protection is implemented via the circuit-breaker -Q4, the specified currents correspond
to the factory setting.
2)
When an uninterruptible power supply is connected, the jumpers between -X46:1/2 and -X46:5/6
must be removed.
3)
The customer is responsible for providing external fuse protection for the uninterruptible power
supply according to the specifications for the 24 V DC power supply used.
