Invertek Drives ODV-42075-IN [4/24] Important safety information

1. Introduction

1.1. Important safety information

This variable speed drive product (Optidrive) is intended for professional incorporation into complete equipment or systems. If installed

incorrectly it may present a safety hazard. The Optidrive uses high voltages and currents, carries a high level of stored electrical

energy, and is used to control mechanical plant that may cause injury. Close attention is required to system design and electrical

installation to avoid hazards in either normal operation or in the event of equipment malfunction.

System design, installation, commissioning and maintenance must be carried out only by personnel who have the necessary training

avoided, could result in injury or death.

The level of integrity offered by the Optidrive control functions – for example stop/start, forward/reverse and maximum speed, is not

Union, all machinery in which this product is used must comply with Directive 89/392/EEC, Safety of Machinery. In particular, the

• Where supply to the drive is through a plug and socket connector, do not disconnect until 10 minutes have elapsed after

• Ensure correct earthing connections. The earth cable must be sufficient to carry the maximum supply fault current which

normally will be limited by the fuses or MCB

• The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and wait 10 minutes before

starting any work on it

• Parameter P-01 can be set to operate the motor at up to 60,000 rpm, hence use this parameter with care.

• If it is desired to operate the drive at any frequency/speed above the rated speed (P-09/ P-10) of the motor, consult the

• Relative humidity must be less than 95% (non-condensing).

• Ensure that the supply voltage, frequency and no. of phases (1 or 3 phase) correspond to the rating of the Optidrive as

• An isolator should be installed between the power supply and the drive.

• Never connect the mains power supply to the Output terminals U, V, W.

• Suitably rated fuses or MCB should be fitted in the mains supply to the drive

• Do not install any type of automatic switchgear between the drive and the motor

• Wherever control cabling is close to power cabling, maintain a minimum separation of 100 mm and arrange crossings at

• Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be

For use on domestic supplies, screened motor cable must be used with the screen terminated to earth on both motor and drive

sides. The installation must be carried out by qualified installation engineers, observing good wiring practice such as power and signal

cable segregation and correct screening techniques to minimise emissions. When installed in this way, the Optidrive with built-in filter

has emission levels lower than those defined in EN61800-3 category C2 for 1

st

up to 5m.

For cable lengths above 5m, the emission levels may exceed those defined by EN61800-3 cat C2. In this case, further mitigation

environment) are upheld for screened cable lengths of up to 25m. The cable

screen should be connected to earth on both the drive and motor sides.
