Hazards
WARNING!
This equipment can endanger life through rotating machinery and high voltages.
Failure to observe the following will constitute an ELECTRICAL SHOCK HAZARD.
This is a product of the restricted sales 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.
This product is designated as “professional equipment” as defined in EN61000-3-2.
Permission of the supply authority shall be obtained before connection to the low
voltage supply.
• 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 3 minutes for the dc link terminals (DC+ and DC-) to discharge
to safe voltage levels (
confirm that the voltage is less than 50V.
• Never perform high voltage resistance checks on the wiring without first disconnecting the
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: Metal parts 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. Refer to page 3-1.
SSD 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:
• The motor speed may not be controlled
• The direction of rotation of the motor may not be controlled
• The motor may be energised
Guards
The user must provide guarding and /or additional safety systems to prevent risk of injury and
electric shock.
Protective Insulation
• All control and signal terminals are SELV, i.e. protected by double insulation. Ensure all
wiring is rated for the highest system voltage.
Note: Thermal sensors contained within the motor must be double insulated.
• All exposed metalwork in the Inverter is protected by basic insulation and bonding to a
safety earth.
RCDs
These are not recommended for use with this product but ,where their use is mandatory, only
Type B RCDs should be used.
