4.3.3 Power Supply
The GAT NET.Controller S 7000 is connected to the mains power supply via an external power supply unit. De-
pending on the type of power supply unit and the country, mains voltage may be UAC 230 V or UAC 115 V (please
refer to technical data). The power supply is connected to the controller via the MOLEX plug shown in Figure 4.7.
Figure 4.7 - Connection of the power supply on the GAT NET.Controller S 7000
The power supply unit may be placed in the designated storage place inside the slave controller.
There are two different types of power supply connections:
1. The power supply can be connected to each slave controller individually.
2. The power supply is connected to a single or a few slave controllers, which in turn supply the remaining slave
controllers via the RS 485 cable. In this case, the “power plug” must be inserted for those slave controllers
which are not supplied directly.
Note: A power supply must always be connected to the master controller and the first slave controller. If 5 or
more slave controllers are used in one line a second power supply is required at the fifth controller.
Figure 4.8 - Power transmission via RS 485 interface
Pay attention to the direction of the supply, as power is transferred only via the “RS 485 OUT” socket.
Attention, the maximum total cable length, if the power is transmitted from a master or slave controller to
a subsequent controller, is 200 metres.
