Electrical Shock and Burn Hazard
When using instruments such as oscilloscopes to work on live equipment, the
Warning! oscilloscope's chassis should be grounded and a differential amplifier input should
be used.
Care should be used in the selection of probes and leads and in the adjustment of
the oscilloscope so that accurate readings may be made. See instrument manu-
facturer's instruction book for proper operation and adjustments to the instrument.
Fire and Explosion Hazard
Fires or explosions might result from mounting Drives in hazardous areas such
Warning! as locations where flammable or combustible vapors or dusts are present. Drives
should be installed away from hazardous areas, even if used with motors suitable
for use in these locations..
Strain Hazard
Improper lifting practices can cause serious or fatal injury. Lift only with adequate
Warning! equipment and trained personnel.

is 5 minutes.
If the front plate has to be removed because the ambient temperature is
higher than 40 degrees, the user has to ensure that no occasional contact
with live parts will occur.
Always connect the Drive to the protective ground (PE) via the marked con-
nection terminals (PE2) and the housing (PE1). Adjustable Frequency Drives
and AC Input filters have ground discharge currents greater than 3.5 mA. EN
61800-5-1 specifies that with discharge currents greater than 3.5 mA the pro-
tective conductor ground connection (PE1) must be fixed type and doubled
for redundancy.
The drive may cause accidental motion in the event of a failure, even if it is
disabled, unless it has been disconnected from the AC input feeder.
Drives and motors must be grounded according to NEC (for USA) and EN
60204 (for Europe).
Replace all covers before applying power to the Drive. Failure to do so may
result in death or serious injury.
Adjustable frequency drives are electrical apparatus for use in industrial
installations. Parts of the Drives are at high voltage during operation. The
electrical installation and the opening of the device should therefore only be
carried out by qualified personnel. Improper installation of motors or Drives
may therefore cause the failure of the device as well as serious injury to
persons or material damage. Follow the instructions given in this manual and
observe the local and national safety regulations applicable..
Do not connect power supply voltage that exceeds the standard specification
voltage fluctuation permissible. If excessive voltage is applied to the Drive,
damage to the internal components will result.
Do not operate the Drive without the ground wire connected. The motor
chassis should be grounded to earth through a ground lead separate from all
other equipment ground leads to prevent noise coupling.
