DIB-500 R4.1 Setup and commissioning
Connection to the electrical system
Risk of short circuit.
The product may be damaged if the live wires of the voltage supply cable are connected
without grounding. In addition, an incorrectly connected earthing cable can cause a
short circuit, e.g. if the voltage source requires grounding on the positive terminal, the
earthing cable, however, is connected to the terminal marked with "-".
Ensure that the reference potential has already been defined or that this process
step is performed first, see section 5.6.2 on page 108.
Risk of electric shock
Electric shock when touching live parts. Hardware components in the equipment cabi-
net are live.
When performing work in the equipment cabinet, ensure that the voltage source on
site is switched off. This must have been checked with a voltmeter.
1. Connect the positive voltage supply cable with the terminal (2) identified by "+",
refer to Figure 5.16.
Figure 5.16 Voltage supply connector
2. Connect the negative voltage supply cable with the terminal (1) identified by "-",
refer to Figure 5.16.
You have successfully connected the power supply cables.
Switching on the Voltage Source Later on
Since the commissioning of the network requires additional work steps that need to be
performed in the equipment rack, the voltage source must stay switched off for the time
being. Switching on the voltage source is required only later on for the configuration.
