To Prevent Electric Shock
◆
Never wire the controller while the power is on. Always keep the circuit breaker in OFF
state.
To Prevent Damage to the Equipment
◆
Cover the top of the controller with a temporary cloth or paper during installation so
as to prevent foreign matter such as metal shavings, oil and water from falling into the
