Figure 2-21. Supply of Peripheral Unit without Modem
You are directed to always check that the utilized a.c. power supply meets the quality
requirements of the peripheral unit, (for example the class of the network).
Take into consideration the extra load caused by any peripheral unit:
• When an intermediate isolating transformer is used in the cabinet to convert a two-phase
network to a single-phase network.
• From a fusing viewpoint.
Given the above rules, you can use any spare power outlet in the cabinet or you can arrange for
an additional branching socket.
