Safety 1-3
AC30 series Variable Speed Inverter
WARNING! - Ignoring the following may result in injury or damage to equipment
SAFETY
Where there is conflict between EMC and Safety requirements, personnel safety shall always take precedence.
• Never perform high voltage resistance checks on the
wiring without first disconnecting the inverter from the
circuit being tested.
• Whilst ensuring ventilation is sufficient, provide guarding
and /or additional safety systems to prevent injury or
damage to equipment.
• When replacing an inverter in an application and before
returning to use, it is essential that all user defined
parameters for the product’s operation are correctly
installed.
• All control and signal terminals are SELV, i.e. protected 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.
EMC
• In a domestic environment this product may cause radio
interference in which case supplementary mitigation
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 for frames sizes D & E (7.5kW).
Permission of the supply authority shall be obtained before
connection to the public low voltage supply.
Frame sizes E (11kW) to N harmonics conform to the limits of
IEC61000-3-12:2011 (table 4).
WARNING! – Control Unit Removal / Fitting
Isolate supply before plugging or unplugging control unit to the power stack.
