  • Page 51: Figure 4.1 Connecting An External Battery

    7400 system is as follows: 1) The battery cable is provided with the OfficeServ 7400 system. It consists of a red line and a blue line labelled GND (red line) and -48VDC (blue line) at one end. It has a connector for the battery socket of the OfficeServ 7400 system at the other end.

  • Page 52: Connecting An External Rectifier

    The internal power source has insufficient capacity. The procedure to connect an external rectifier is as follows: 1) Switch off the power to the OfficeServ 7400 and external rectifier. 2) There are three screws to connect the power cable (Figure 4.2) to connectors A and B (GND and -54 V) on the rear panel of the external rectifier (Figure 4.3)

  • Page 53

    An external battery connected to an external rectifier should have the same ca- pacity as that of the OfficeServ 7400 system. In addition, the procedure and the precautions to take are the same. For details of the capacity of the external bat- tery, refer to 4.1 Connecting External Batteries.

  • Page 54: Chapter 5. Connecting Power Cables

    AC power of the system supports 110V, 220 V (Free Voltage). Make sure that the input power of the OfficeServ 7400 is within the range 100~240 V (AC) and other electric devices, such as motors and compressors, do not use the same input power.
