WARNING In order to ensure correct and safe operation, it is vital the following instructions are strictly adhered to:

Operation of a motor with a higher nominal power than the inverter or a nominal power less than half that of the inverter is not allowed. The inverter must only be operated when the nominal current in P083 exactly matches the motor rating plate nominal current.

The motor data parameters must be accurately entered (P080-P085) and an auto-calibration performed (P088=1) before the motor is started. Unstable/unpredictable motor operation (eg. reverse rotation) may result if this is not done. If this instability occurs, the mains supply to the converter must be disconnected.

When using the analogue input, the DIP switches must be correctly set and the analogue input type selected (P023) before enabling the analogue input with P006. If this is not done, the motor may start inadvertently.

If the Inverter is to be installed at an altitude >1000m, derating will be required.(Refer to DA64 Catalogue)

Do not drop the inverter or expose to sudden shock.

Do not install the inverter in an area where it is likely to be exposed to constant vibration.

Do not install the inverter near sources of electro-magnetic radiation.

Do not install the inverter in an environment, which contains atmospheric pollutants such as dust, corrosive gases, etc.

Take care to site the inverter away from potential water hazards. e.g. Do not install the inverter beneath pipes that are subject to condensation. Avoid installing the inverter where excessive humidity and condensation may occur.

Ensure that the inverter’s air vents are not obstructed, including the air vent at the front of the unit, which should be at least 15mm from any obstruction. Additional ventilation may be required for horizontal mounting.

Make sure that there is an adequate air-flow through the cabinet, as follows: 1. Using the formula below, calculate the air-flow required:

Air-flow (m3 / hr) = (Dissipated Watts / T) x 3.1 2. If necessary, install cabinet cooling fan(s).

Note: Dissipation (Watts) = 3-5% of inverter rating.

T = Allowable temperature rise within cabinet in °C. 3.1 = Specific heat of air at sea level.

1.2 Wiring Guidelines to Minimise the Effects of EMI

The inverters are designed to operate in an industrial environment where a high level of Electro-Magnetic Interference (EMI) can be expected. Usually, good installation practices will ensure safe and trouble-free operation. If problems are encountered, the following guidelines may prove useful. In particular, grounding of the system at the inverter, as described below, may prove effective. Figures 1.2.1-1.2.3 illustrate how an RFI suppression filter should be installed and connected to the MICROMASTER Vector.

(1)Ensure that all equipment in the cubicle is well earthed using short, thick earthing cable connected to a common star point or busbar. It is particularly important that any control equipment that is connected to the inverter (such as a PLC) is connected to the same earth or star point as the inverter via a short, thick link. Flat conductors (e.g. braids or metal brackets) are preferred as they have lower impedance at high frequencies.

The return earth from motors controlled by the inverter should be connected directly to the earth connection (PE) on the associated inverter.

(2)On the MIDIMASTER Vector, use saw-tooth washers when mounting the inverter and ensure that a good electrical connection is made between the heatsink and the panel, removing paint if necessary.

(3)Wherever possible, use screened leads for connections to the control circuitry. Terminate the ends of the cable neatly, ensuring that unscreened wires are as short as possible. Use cable glands whenever possible.

(4)Separate the control cables from the power connections as much as possible, using separate trunking, etc. If control and power cables cross, arrange the cables so that they cross at 90° if possible.

(5)Ensure that 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 particularly important if the contactors are controlled from the relay on the inverter.

(6)Use screened or armoured cables for the motor connections and ground the screen at both ends via the cable glands.

(7) If the drive is to be operated in an Electro-magnetic noise-sensitive environment, the RFI filter should be used to reduce the conducted and radiated interference from the inverter. For optimum performance, there should be a good conductive bond between filter and metal mounting plate.

(8) For Frame Size A units (Fig.1.2.1), the flat earth braid strap, supplied with the unit, should be fitted to minimise emissions.

1.3 Electrical Installation - General Notes

1.3.1 Operation with Unearthed (IT) Supplies

MICROMASTER / MIDIMASTER Vector were developed for operation on grounded line supplies. These drive units can also be operated on non-grounded line supplies. However, we do not recommend this. However, if the drive units are operated on non-grounded line supplies, then the following points must be carefully observed:

It is mandatory that line reactors are used. They are used to adapt line impedances and to minimize voltage peaks. It is also mandatory to use output reactors.
