Electrical wiring 6 DANGER Electrical wiring Dangerous voltage Even if the auxiliary voltage is switched off, dangerous voltage up to 400 V may exist! Make sure that the device is fully disconnected from auxiliary power and measuring voltage before starting any commissioning or repair work. Connect the power supply only after the wiring has been completed. ̶ ̶ ̶ ̶ The voltmeter must be provided with its own fuse or a circuit breaker. 300 mA fuse or circuit breaker is recommended.
Operation 7 Operation After the power supply is switched on the following values will be displayed successively: 1. Firmware checksum (8 digits, ticker-tape) 2. Firmware version (Ux.xx) 3. Measuring voltage If the measuring voltage is less than 5 V the error message 0000 will be displayed. If the measuring voltage is greater than 400 V the error message HHHH will be displayed. If the measuring voltage is not displayed correctly, check the connecting cable and the polarity. akYtec GmbH · Vahrenwalder Str.
Maintenance 8 Maintenance The maintenance includes: – – – cleaning of the housing and terminal blocks from dust, dirt and debris checking the fastening of the device checking the wiring (connecting leads, fastenings, mechanical damage) The device should be cleaned with a damp cloth only. No abrasives or solventcontaining cleaners may be used.
