Certification
•
Disconnection device/overcurrent protection: In the building installation, use a
certified 2-pole circuit breaker rated 10A, certified in accordance with the IEC
standard 60947-2 (in the US and Canada use a Listed Brach Circuit protective
circuit breaker). This step is required to provide overcurrent protection and mains
disconnection. The circuit breaker must be easily accessible and marked as the
controller disconnect device.
•
Main Supply Voltage: Permanently connect the controller to the mains in
accordance with the relevant national code. Provide fixed wiring inside a flexible
conduit. Relays must be suitably protected against overcurrent, using a circuit
breaker rated at 10A.
