If the relays are used to switch alternating voltage, it may be necessary to suppress them.
Figure 9.0 shows how to suppress resistive loads (lamp, resistor, ...).
Figure 9.1 shows how to suppress inductive loads (transformer, motor, ...).
Figure 9.2 applies in case all the above solutions fail. In this last case an independantly feeded DC-relay is
used, which is installed as close to the load as possible.
