14.2.4.1 Connecting the Power Supply to the Power Supply Unit
The power supply and the protective conductor are connected to the connection module (plug-
in module III) of the power supply unit. A shielded conductor must be used.
Wire gauges to be used:
‰
1.5 mm
2
(AWG 15) stranded (with wire end ferrule), or
‰
2.5 mm
2
(AWG 13) single-wire
The maximum current consumption in the nominal range and with maximum system
configuration is 2 A. The value of the internal miniature fuse in the power supply unit is
3.15 A inert. To maintain the selectivity in the fuse chain, a 6 A circuit-breaker must be installed
in the network lead.
14.2.4.2 Connecting Signals to the CPU
Connection modules (plug-in module III) are used for the connection at the rear of the CPU.
Maximum wire gauges to be used:
‰

14.2.4.3 Connecting Data Acquisition Modules VCDAU, VDAU, CDAU
The measurement circuits are connected using connection modules (plug-in module I for
currents, plug-in module III for voltages and binary channels) at the rear of the DAU.
