Note
Use a suppressor circuit in environments with high humidity and where sparks might occur at
the relay contacts. This will increase the service life of the relay contacts.
To install the suppressor circuit, connect an RC element or a varistor in parallel with the relay
contacts or load. The dimensions depend on the size of the load.
