lamp. If an inductive load is used, such as a relay coil, the rating should be
reduced to maximum of 2.5 Amps, 250 VAC.
The use of inductive loads can cause excessive arcing of these contacts.
Excessive arcing can cause radiated interference (RFI) that can affect the
Intellisys. An effective way to minimize this interference is to install a RC network
known as an “Arc Suppressor”. The RC network can be installed across the
form “C” contacts that are used in the application. Arc suppressors are normally
sized for specific applications. The general-purpose arc suppressor
P/N…39203443 used in the starter circuit (RC1) can be used for most
applications.
