1 Safety
Before installing and putting the equipment into operation, read these safety instructions and warnings
carefully.
Also read and obey all warning signs attached to the equipment. Make sure that the warning labels are kept
in a legible condition and replace any missing or damaged labels.
Warning
• This equipment contains dangerous voltages and
controls dangerous rotating mechanical parts.
Loss of life, severe personal injury or property
damage can result if the instructions contained in
this Manual are not followed
• Only suitably qualified personnel should work
on this equipment, and only after being familiar
with all safety notices, installation, operation and
maintenance procedures contained in this Manual
• Use only permanently wired input power
connections. The equipment must be grounded
(IEC 536 Class 1, NEC, and other applicable
standards)
• If a Residual Current Circuit Breaker (RCCB or
ELCB) is required, type B with a 300 mA tripping
current must be used (the RCCB. should only
supply one VSD). An unfiltered VSD should be
used or if the VSD has an EMC filter this must be
disconnected, due to the filter leaking current to
earth. The neutral conductor in the system must
be grounded
• Wait at least 5 minutes after the power has
been turned off, before opening the equipment.
The dc-link capacitor remains charged to
dangerous voltages even when the power is
removed. When working on open equipment, note
that live parts are exposed and do not touch such
parts
• Do not connect machines with a 3-phase power
supply, fitted with EMC filters, to a supply via an
ELCB (Earth Leakage Circuit Breaker - see EN
50 178, section 6.5)
• Note that certain parameter settings may cause
the VSD to restart automatically after an input
power failure
• Do not use this equipment as an "emergency
stop" mechanism (see EN 60 204, 9.2.5.4)
• Note that certain parameter settings may cause
the VSD to start automatically
• Obey all general and regional installation and
safety regulations relating to work on low-voltage
installations, as well as regulations covering
correct use of tools and personal protective
equipment

• This equipment is capable of providing internal
motor overload protection in accordance with
UL508C section 42. An external PTC can also
provide motor overload protection via a special
input
• This equipment is suitable for use in a circuit
capable of delivering not more than 100,000
symmetrical amps (rms) for a maximum voltage of
AC 460 V when protected by a time delay fuse.
• Do not use the unit with a motor of a higher
nominal power rating than the VSD, or a nominal
power less than half that of the VSD. Only operate
the VSD when the nominal current in P0305
exactly matches the motor rating plate nominal
current
• When using the analog inputs, the DIP switches
must be correctly set and the analog inputs cor-
rectly configured before enabling them. If this is
not done, the motor may start inadvertently
Caution
• Do not allow children or the general public to
access or approach this equipment
• Do not install the VSD where it will be subjected
to shock, vibration, electromagnetic radiation,
water hazards, or atmospheric pollutants such as
dust or corrosive gasses
• Keep Operating Instructions, etc., with this
equipment or with the end-user
• Use this equipment only for the purpose
specified by the manufacturer. Do not carry out
any modifications or fit any spare parts, which are
not sold or recommended by the manufacturer; as
this could cause fire, electric shock or other
injuries.
