Operation with ungrounded (IT) supplies

The MICROMASTER will operate from ungrounded supplies and will continue to operate if an input phase is shorted to ground. If an output phase is shorted to ground, the MICROMASTER will trip and indicate F0001.

On ungrounded supplies, it will be necessary to remove the ‘Y’ capacitor from the inside of the unit and fit an output choke. The procedure for removing this capacitor is described in Appendices G, H, I and J.

Operation with Residual Current Device

If an RCD (also referred to as ELCB or RCCB) is fitted, the MICROMASTER inverters will operate without nuisance tripping, provided that:

A type B RCD is used. The trip limit of the RCD is 300mA. The neutral of the supply is grounded. Only one inverter is supplied from each RCD. The output cables are less than 50m (screened) or 100m (unscreened).

Operation with long cables

Caution

The control, power supply and motor leads must be laid separately. Do not feed

them through the same cable conduit/trunking. Never use high voltage insulation test equipment on cables connected to the inverter.

All inverters will operate at full specification with cable lengths up to 50 m screened or 100 m unscreened.

2.4.2 Power and motor connections

Warning

♦ Isolate the mains electrical supply before making or changing connections to

the unit.

♦ Ensure that the inverter is configured for the correct supply voltage: single /

three-phase 230 V MICROMASTERS must not be connected to a higher voltage supply.

♦ When synchronous motors are connected or when coupling several motors in

parallel, the inverter must be operated with voltage/frequency control characteristic (P1300 = 0, 2 or 3).

Caution

After connecting the power and motor cables to the proper terminals, make sure that the covers have been replaced properly before supplying power to the unit!

Note

♦ Ensure that the appropriate circuit-breakers/fuses with the specified current

rating are connected between the power supply and inverter (see Tables starting on page 77).

♦ Use Class 1 60/75

C copper wire only (for UL compliance). For tightening

torque see table on page 79.

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

Access to the power and motor terminals

The procedure for accessing the power and motor terminals on the MICROMASTER 440 Inverter is illustrated in Appendices. Please also refer to the photographs showing the Power Terminal connections and the Control Terminal connections on the inside of the back cover of this manual.

When the covers have been removed to reveal the terminals, connect the power and motor connections as shown on the next page.

2.4.3 Avoiding Electro-Magnetic Interference (EMI)

The inverters are designed to operate in an industrial environment where a high level of EMI can be expected. Usually, good installation practices will ensure safe and trouble-free operation. If you encounter problems, follow the guidelines stated below.

Action to Take

 Ensure that all equipment in the cubicle is well grounded using short, thick

grounding cable connected to a common star point or busbar

 Make sure that any control equipment (such as a PLC) connected to the

inverter is connected to the same ground or star point as the inverter via a short thick link.

 Connect the return ground from the motors controlled by the inverters directly

to the ground connection (PE) on the associated inverter

 Flat conductors are preferred as they have lower impedance at higher

frequencies

 Terminate the ends of the cable neatly, ensuring that unscreened wires are as

short as possible

 Separate the control cables from the power cables as much as possible, using

separate trunking, if necessary at 90º to each other.

 Whenever possible, use screened leads for the connections to the control

circuitry

 Ensure that the contactors in the cubicle are suppressed, either with R-C

suppressors for AC contactors or 'flywheel' diodes for DC contactors fitted to the coils. Varistor suppressors are also effective. This is important when the contactors are controlled from the inverter relay

 Use screened or armored cables for the motor connections and ground the

screen at both ends using the cable clamps

Warning Safety regulations must not be compromised when installing inverters!

2.4.4 Screening Methods

Frame Sizes A, B and C

For frame sizes A, B and C the Gland Plate Kit is supplied as an option. It allows easy and efficient connection of the necessary screening. See the Gland Plate Installation Instructions contained on the Document CD-ROM, supplied with the MM440.

Frame Sizes D, E and F

The Gland Plate is factory fitted. The installation of the screening is accomplished using the same methodology as in frame sizes A, B and C.
