IMPORTANT: Please read this information BEFORE installing the equipment.
Requirements
Intended Users
This manual is to be made available to all persons who are required to install, configure or service equipment described
herein, or any other associated operation. Information given is intended to highlight safety issues, and to enable you to
obtain maximum benefit from the equipment.
Application Area
The equipment described is intended for industrial motor speed control using AC induction or AC synchronous machines.
Personnel
Installation, operation and maintenance of the equipment should be carried out by qualified personnel. A qualified person is
someone who is technically competent and familiar with all safety information and established safety practices; with the
installation process, operation and maintenance of this equipment; and with all the hazards involved.
Hazards
WARNING!
This equipment can endanger life through rotating machinery and high voltages.
Failure to observe the following will constitute an ELECTRICAL SHOCK HAZARD.
The 400V products in this range are of the Restricted Distribution class according to IEC 61800-3.
In a domestic environment, this product may cause radio interference in which case the user may be required to
take adequate measures.
•The equipment must be permanently earthed due to the high earth leakage current.
•The drive motor must be connected to an appropriate safety earth.
•The equipment contains high value capacitors which take time to discharge after removal of the mains supply.
•Before working on the equipment, ensure isolation of the mains supply from terminals L1, L2 and L3. Wait for at least
5 minutes for the dc link terminals (DC+ and DC-) to discharge to safe voltage levels (<50V). Measure the DC+ and
DC- terminal voltage with a meter to confirm that the voltage is less than 50V.
•Never perform high voltage resistance checks on wiring without first disconnecting drive from the circuit being tested.
•When replacing a drive in an application and before returning to use, it is essential that all user defined parameters for
the product’s operation are correctly installed.
•This equipment contains electrostatic discharge (ESD) sensitive parts. Observe static control precautions when
handling, installing and servicing this product.
IMPORTANT: Internal parts of the drive may reach a temperature of 90 degrees centigrade in operation.
Application Risk
The specifications, processes and circuitry described herein are for guidance only and may need to be adapted to the user’s
specific application. Eurotherm Drives does not guarantee the suitability of the equipment described in this Manual for
individual applications.
Risk Assessment
Under fault conditions, power loss or other operating conditions not intended, the equipment may not operate as specified.
In particular: ●motor speed may not be controlled motor direction may not be controlled motor may be en ergised
Guards
The user must provide guarding and /or additional safety systems to prevent risk of injury and electric shock.
Protective Insulation
All control/signal terminals are SELV, i.e. protected by double insulation. Ensure wiring is rated for highest system voltage.
All exposed metalwork in the Inverter is protected by basic insulation and bonding to a safety earth.
Note: Thermal sensors contained within the motor must be double insulated.
RCDs
These are not recommended for use with this product but ,where their use is mandatory, only Type B RCDs should be used.
