RECOMMENDATIONS FOR INSTALLATION
• Input signal leads must be installed in grounded conduits and away from power or contactor wires.
• Instruments must be powered only by an exclusive power supply.
• Installing RC filters (47 Ω and 100 nF, serial) is strongly recommended at contactor coils or any other inductors.
• System failure should always be taken into account when designing a control panel to avoid irreversible damage to
equipment or injury to people. The RL1 and RL2 output relays, used as alarms, do not warrant total protection.
• Wires section: minimum gauge 0.14 mm².
