Charger Model: 3634778 before connecting the power input (1) first make sure the charger is connected rated input voltage and the grid voltage used are the same. (2) charger input power for three-phase four-wire system, where three connected three-phase transmission line (FireWire) ESD5550, yellow and green wire is the ground wire. (3) the charger is connected to the external network through the power cable. To ensure the safety of ESD, extranet connection requires the installation of the power supply circuit breaker and insurance ESD5500E, the capacity of the circuit breaker is about 2.5-3 times the rated input current. Charger Model: 3972730 Charging ? Connect the charger and the battery charging plug; ? Turning the power grid; automatic shutdown ? After charging is completed, adequate light, the information window shows the battery voltage. Note: n charging can press the INFO button checked other charging information; n as fault lights, check the error code in the message window after control fault code table; n the process of charging the battery charging current versus voltage rise gradually declined.
