Glass cleaning machine electricity safety
1. Safety inspection of the glass cleaning machine project
A. Often check whether the motor lead wiring is firm, reliable and intact.
B, the insulation resistance of the lead and the case by 500 volt megohm table should be greater than 20 megohms.
2. cable
A. The length of the cable line of the glass cleaning machine is generally not more than 10 meters.
B, the cable from the leakage circuit breaker to the cleaning machine must be connected with a single cable line.
C. The motor of the glass washer shall be grounded reliably through the cable (there is grounding marks in the motor junction box).
D, the equipment must be placed in a dry place, no rain invasion, to prevent leakage, do good safety measures. Insulated gloves and insulating shoes must be worn during operation (provided by the user).
3. Power supply and control electrical appliances
A. Confirm whether the power supply meets the nameplate requirements.
B. The power input of hot water high voltage cleaning machine must be installed with control electrical appliances, such as leakage circuit breaker, overload, short circuit breaking single-phase electric machine protector, etc. (provided by the user). The specifications shall meet the requirements of the motor nameplate.
C. Note: After the installation or operation of the leakage protector for a certain period (generally every one month), it is necessary to press the test button under the closing power state to check whether the leakage protection performance is normal and reliable.(Every time the test button, the protector should act once) unloaded and sent to the manufacturer for repair.
