Invertek Drives Ltd cannot be held responsible for any loss or damages regarding a Cyber Security breach.

Warranty

The manufacturer accepts no liability for any damage caused during or resulting from transport, receipt of delivery, installation or commissioning. The manufacturer also accepts no liability for damage or consequences resulting from inappropriate, negligent or incorrect installation, incorrect adjustment of the operating parameters of the drive, incorrect matching of the drive to the motor, incorrect installation, unacceptable dust, moisture, corrosive substances, excessive vibration or ambient temperatures outside of the design specification.

The local distributor may offer different terms and conditions at their discretion, and in all cases concerning warranty, the local distributor should be contacted first.

Safety

Only qualified electrical personnel familiar with the construction and operation of this equipment and the hazards involved should install, adjust, operate, or service this equipment.

Failure to observe this precaution could result in severe bodily injury or loss of life.

Danger: Indicates a risk of electric shock, which, if not avoided, could result in damage to the equipment and possible injury or death.	Danger: Indicates a potentially hazardous situation other than electrical, which if not avoided, could result in damage to property.
This variable speed drive product is intended for professional incorporation into complete equipment or systems as part of a fixed installation. If installed incorrectly it may present a safety hazard. The drive 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. Only qualified electricians are allowed to install and maintain this product. System design, installation, commissioning and maintenance must be carried out only by personnel who have the necessary training and experience. They must carefully read this safety information and the instructions in this Guide and follow all information regarding transport, storage, installation and use of the drive, including the specified environmental limitations. Do not perform any flash test or voltage withstand test on the drive. Any electrical measurements required should be carried out with the drive disconnected. Electric shock hazard! Disconnect and ISOLATE the drive before attempting any work on it. High voltages are present at the terminals and within the drive for up to 5 minutes after disconnection of the electrical supply. Always ensure by using a suitable multimeter that no voltage is present on any drive power terminals prior to commencing any work. Where supply to the drive is through a plug and socket connector, do not disconnect until 5 minutes have elapsed after turning off the supply. Ensure correct earthing connections and cable selection as defined by local legislation or codes. The drive may have a leakage current of greater than 3.5mA; furthermore the earth cable must be sufficient to carry the maximum supply fault current which normally will be limited by the fuses or MCB. Suitably rated fuses or MCB should be fitted in the mains supply to the drive, according to any local legislation or codes. Do not carry out any work on the drive control cables whilst power is applied to the drive or to the external control circuits. The “Safe Torque Off” Function does not prevent high voltages from being present at the drive power terminals. This drive contains high voltage capacitors that take time to discharge after removal of the main supply. Before working on the drive, ensure isolation of the main supply from line inputs. Wait ten (10) minutes for the capacitors to discharge to safe voltage levels. Failure to observe this precaution could result in severe bodily injury or loss of life. When installing the drive on any power supply where the phase-ground voltage may exceed the phase-phase voltage (typically IT supply networks or Marine vessels) it is essential that the internal EMC filter ground and surge protection varistor ground (where fitted) are disconnected. If in doubt, refer to your Sales Partner for further information.	Within the European Union, all machinery in which this product is used must comply with the Machinery Directive 2006/42/EC, Safety of Machinery. In particular, the machine manufacturer is responsible for ensuring that the electrical equipment complies with EN60204-1 and providing a disconnecting device which must be one of the following types: A switch-disconnector, utilization category AC-23B (EN 60947-3). A circuit breaker suitable for isolation in accordance with EN 60947-2. A disconnector with an integrated auxiliary contact that ensures under all circumstances the switching devices break the load circuit prior to opening of the main contacts of the disconnector (EN 60947-3). For installation in other regions, conformance with local electrical regulations and codes of practice must be adhered to. The level of integrity offered by the drive control input functions – for example stop/start, forward/reverse and maximum speed, is not sufficient for use in safety-critical applications without independent channels of protection. All applications where malfunction could cause injury or loss of life must be subject to a risk assessment and further protection provided where needed. The driven motor can start at power up if the enable input signal is present. The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and wait 5 minutes before starting any work on it. Never carry out any work on the Drive, Motor or Motor cable whilst the input power is still applied. The drive can be programmed to operate the driven motor at speeds above or below the speed achieved when connecting the motor directly to the mains supply. Obtain confirmation from the manufacturers of the motor and the driven machine about suitability for operation over the intended speed range prior to machine start up. Do not activate the automatic fault reset function on any systems whereby this may cause a potentially dangerous situation. The drive must be installed in a pollution degree 2 environment, mounted in a cabinet with IP54 or better. The drive is intended for indoor use only. When mounting the drive, ensure that sufficient cooling is provided. Do not carry out drilling operations with the drive in place, dust and swarf from drilling may lead to damage. The entry of conductive or flammable foreign bodies should be prevented. Flammable material should not be placed close to the drive. 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 drive as delivered. Never connect the mains power supply to the Output terminals U, V, W. 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 90 degrees. Ensure that all terminals are tightened to the appropriate torque setting. Do not attempt to carry out any repair of the drive. In the case of suspected fault or malfunction, contact your local Invertek Drives Sales Partner for further assistance. Do not operate the drive with any of the enclosure covers removed.
