Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death.
This controller is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD). Otherwise, it may cause electrical shock and fi re in case of equipment breakdown or insulation breakdown. Earth Leakage Circuit Breaker (ELCB) must be incorporated in the fixed wiring in accordance with the wiring regulations. The Earth Leakage Circuit Breaker (ELCB) must be an approved 10 A, having a contact separation by 3 mm in all poles.
Provide a power outlet to be used exclusively for this controller.
Turn off the circuit breaker of the controllers before installation.
Do not supply power to the controller until all wiring is completed or reconnected and checked.
Fix the power supply wiring securely with the clamper so that the power supply terminal board part is free of tension (external force) when pulled. Loose connection of the terminal board may occur fi re.
To prevent possible hazards from insulation failure, the controller must be grounded.
Select an installation location which is rigid and strong enough to support or hold the controller, and select a location for easy maintenance.
This product must not be modified or disassembled under any circumstances. Modified or disassembled controller may cause fi re, electric shock or injury.
Do not clean inside the controller by users. Engage authorized dealer or specialist for cleaning.
