Surge Protection Module - INVT Goodrive880 Series Hardware Manual

Goodrive880 Series Active Rectifier Hardware Manual
Note:
Ensure that all terminals and fiber optic plugs are installed in place for effective electrical connection.

The module is grounded through contact between its exposed metal shell and the assembly board

inside the cabinet, so the assembly board must be an exposed metal plate. To ensure the reliable
operation of the module and meet the EMC requirements, please tighten the screws to ensure reliable
grounding.
The IVDM-10 AC voltage detection module is connected to the fiber optic expansion module EC-TX821/TX823
through optical fibers, transmitting the detection signal to the control box. Figure 6-2 shows the external
wiring diagram of the IVDM-10 module, taking the fiber optic expansion module EC-TX823 and active
rectifier filter unit as an example.

STATUS
Note:The 3PH AC voltage line sequence of the IVDM-10 module must be consistent with the phase
sequence of the incoming cable of the rectifier filter unit. Otherwise, the overcurrent fault will occur in the
rectifier unit.
For details about AC voltage detection module, refer to the AC Voltage Detection Module Manual.

6.2 Surge protection module

For A3–A7 structure products, buffer components are not configured with surge protection modules, it is
necessary to configure additional surge protection module on the grid side. The surge protection module is
used to absorb the surge or peak voltage among the AC power grid, ensuring that the rectifier module is not
damaged. The dimensions of the surge protection module is 98x86 x 80 mm (W*D*H), as shown in Figure 6-3.
