Warning! If the wiring does not meet specifications, the warranty becomes void. Blowing a fuse or firing automatic protection indicates a short circuit or work in conditions of overload.Before replacing the fuse or re-running the compressor malfunction must be found and eliminated. All maintenance work on the control panel should be performed only by qualified personnel, failure to do so could cause damage to the unit and the denial of warranty service.The unit of voltage control and phase (optional) Device control voltage and the phase is designed to protect motors and other consumers of the three-phase current at inappropriate reduced symmetric voltage between phases at the asymmetry of the stress in the reverse alternation of phases.For any unacceptable variations in the three-phase voltage or changing the order of phase sequence voltage control device is triggered, leading to disabling the power supply to all input terminals of the control system.
