6.1 Recommendation
1. Input signal wires should be laid out away from power lines and preferably inside grounded
conduits.
2. Instrument mains (line) supply should be suitable for this purpose and should not be shared.
3. In controlling and monitoring applications, possible consequences of any system failure must be
considered in advance. The internal alarm relay dos not warrant total protection.
4. RC filters (47 and 100nF, serial) are highly recommended for valve and contactor coils, etc.
