2 Safety and CE compliance
Before installing and putting the equipment into operation, read these safety in-
structions 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.
• This equipment contains dangerous voltages and controls dangerous rotating me-
chanical 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 be-
ing familiar with all safety notices, installation, operation and maintenance proce-
dures 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 un-
filtered VSD should be used or if the VSD has an EMC filter this must be discon-
nected, 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 af-
ter 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 covering correct use of tools and
personal protective equipment
• This equipment is capable of providing internal motor overload protection in ac-
cordance 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 230/460 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 correctly configured before enabling them. If this is not done, the
motor may start inadvertently
