2. INSTALLATION

2.3 Electrical Installation

The electrical connectors on the MICROMASTER are shown in Figure 3. Connect the cables to the power and control terminal blocks in accordance with the information supplied in sections 2.3.1 - 2.3.4. Ensure that the leads are connected correctly and the equipment is properly earthed as shown in Figure 3.

CAUTION

The control, power supply and motor leads must be laid separately. They must not be fed through the same cable conduit/trunking.

Use screened cable for the control lead. Use Class 1 60/75oC copper wire only (for UL compliance). Tightening torque for the power (mains input and motor) terminals is 1.1 Nm.

To tighten up the power/motor terminal screws use a 4 - 5 mm cross-tip screwdriver.

2.3.1 Power and Motor Connections - Frame Size A

Ensure that the power source supplies the correct voltage and is designed for the necessary current (see section 7). Ensure that the appropriate circuit-breakers/fuses with the specified current rating are connected between the power supply and inverter (see section 7).

Connect the power and motor connections as shown in Figure 3.

WARNING

Isolate the supply before making or changing connections.

Ensure that the motor is configured for the correct supply voltage. Single/three phase 230 V

MICROMASTERS must not be connected to a 400 V three phase supply.

When synchronous machines are connected or when coupling several motors in parallel, the inverter must be operated with voltage/frequency control characteristic (P077= 0 or 2).
