2. Installation

English

2.3.1 Mains Cable Connections

Ensure that the power source supplies the correct voltage and is designed for the necessary current. Ensure that the appropriate circuit-breakers with the specified current rating are connected between the power supply and CombiDrive® (see section 6).

Use Class 1 60/75oC copper wire only.

Use a 4-core screened cable (for cross-section of each core see section 6). If crimp terminals are used then they must be insulated. If crimps are not used, the strip length must not exceed 5 mm.

Feed the power cable into the inverter via the gland hole nearest to the motor shaft (see Figure 3). Connect the power leads to terminals L1, L2, L3 and the separate earth.

Use a 4 - 5 mm cross-tip screwdriver to tighten the terminal screws.

2.3.2 Control Cable Connections

CAUTION

The control and power supply cables must be laid separately. They must not be fed throug the same cable conduit/trunking.

Use screened cable for the control lead.

Feed the control cable into the inverter via the appropriate gland (seehole Figure 3). Unplug connector block PL800 from the PCB and connect the control wires in accordance with the information given in Figures 4a and 4b (also see Figure 3).

IMPORTANT: A wire linkmust be fitted between control terminals 5 (DIN1) and 8 (P15+) otherwise the CombiDrive® will not operate when control potentiometer R314 is used. The wire link must be removed when operation via a run/stop switch is required.

Plug the connector block back into the PCB, refit the cover and tighten the four securing screws.
