● Never repair or main the controller while the power is on. Follow the repair and maintenance instructions in
this user manual.
● Repair or maintain the controller when its voltage is lower than 36 VAC, about 10 minutes after the
controller is powered off. Otherwise, the residual voltage in the capacitor may result in personal injury.
● Disconnect the controller from all power supply before starting any repair or maintenance operations.
● All the pluggable components must be plugged or removed only after power-off.
