1 Safety and CE compliance
Before installing and putting the equipment into operation, read these safety instructions and warnings carefully.
Also read and obey all the 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. Further information can be found in the Operating /
Engineering Manuals.
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 man-
ual
• Use only permanently wired input power connec-
tions. 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 three-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 high-
voltage installations, as well as regulations cov-
ering 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 digital in-
put
• This equipment is suitable for use in a circuit ca-
pable of delivering not more than 100,000 sym-
metrical amps (rms) for a maximum voltage of AC
230 / 460 V * when protected by a time delay fuse
as detailed in the SED2 Reference Manual
• Do not use the unit with a motor of a higher nomi-
nal 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 ex-
actly matches the motor rating plate nominal cur-
rent
• 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 ac-
cess 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 equip-
ment or with the enduser
• Use this equipment only for the purpose specified
by the manufacturer. Do not carry out any modifi-
cations or fit any spare parts, which are not sold
or recommended by the manufacturer; as this
could cause fire, electric shock or other injuries
