Ignoring the following may result in injury or damage to equipment
Where there is conflict between EMC and Safety requirements, personnel safety shall always take
precedence.
Safety
• Never perform high voltage resistance checks on the
wiring without first disconnecting the drive from the cir-
cuit being tested.
• Whilst ensuring ventilation is sufficient, provide guard-
ing and /or additional safety systems to prevent injury
or damage to equipment.
• When replacing a drive in an application and before
returning to use, it is essential that all user defined pa-
rameters for the product’s operation are correctly in-
stalled.
• All control and signal terminals are SELV, i.e. protect-
ed by double insulation. Ensure all external wiring is
rated for the highest system voltage.
• Thermal sensors contained within the motor must have
at least basic insulation.
• All exposed metalwork in the Inverter is protected by
basic insulation and bonded to a safety earth.
• RCDs are not recommended for use with this product
but, where their use is mandatory, only Type B RCDs
should be used.
EMV
• In a domestic environment this product may cause ra-
dio interference in which case supplementary mitiga-
tion measures may be required.
• This equipment contains electrostatic discharge (ESD
sensitive parts. Observe static control precautions when
handling, installing and servicing this product.
• This is a product of the restricted sales distribution
class according to IEC 61800-3. It 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.
Control Unit Removal / Fitting
Isolate supply before plugging or unplugging control unit to the power stack.
CAUTION!
APPLICATION RISK
• The specifications, processes and circuitry described
herein are for guidance only and may need to be adapt-
ed to the user’s specific application. We can not guar-
antee the suitability of the equipment described in this
Manual for individual applications.
RISK ASSESSMENT
Under fault conditions, power loss or unintended oper-
ating conditions, the drive may not operate as intended.
In particular:
• Stored energy might not discharge to safe levels as
quickly as suggested, and can still be present even
though the drive appears to be switched off
• The motor's direction of rotation might not be controlled
• The motor speed might not be controlled
• The motor might be energised
A drive is a component within a drive system that may
influence its operation or effects under a fault condition.
Consideration must be given to:
• Stored energy
• Supply disconnects
• Sequencing logic
• Unintended operation
