1. PRECAUTIONS AND
WARNINGS
According to the EEC standards the DV300 and
accessories must be used only after checking that the
machine has been produced using those safety devices
required by the 89/392/EEC set of rules, as far as the
machine industry is concerned.
Drive systems cause mechanical motion. It is the re-
sponsibility of the user to insure that any such motion
does not result in an unsafe condition. Factory provided
interlocks and operating limits should not be bypassed
or modified.
WARNING - ELECTRICAL SHOCK AND BURN
HAZARD:
When using instruments such as oscilloscopes to work
on live equipment, the 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
manufacturer’s instruction book for proper operation
and adjustments to the instrument.
WARNING - FIRE AND EXPLOSION HAZARD:
Fires or explosions might result from mounting drives
in hazardous areas such 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.
WARNING - STRAIN HAZARD:
Improper lifting practices can cause serious or fatal
injury. Lift only with adequate equipment and trained
personnel.
WARNING:
Replace all covers before applying power to the drive.
Failure to do so may result in death or serious injury.
WARNING:
Adjustable speed drives are electrical apparatus for use
in industrial installations. Parts of the drives are
energized 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.
CAUTION:
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.
CAUTION:
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.
The grounding connector shall be sized in accordance
with the NEC or Canadian Electrical Code. The
connection shall be made by a UL listed or CSA certified
closed-loop terminal connector sized for the wire gauge
involved. The connector is to be fixed using the crimp
tool specified by the connector manufacturer.
CAUTION:
Do not perform a megger test between the Drive
terminals or on the control circuit terminals.
CAUTION:
Because the ambient temperature greatly affects drive
life and reliability, do not install the drive in any location
that exceeds the allowable temperature. Leave the
ventilation cover attached for temperatures of 40° C
(104° F) or below.
CAUTION:
If the drive’s Fault Alarm is activated, consult the
TROUBLESHOOTING section of the instruction book,
and after correcting the problem, resume operation. It
is not recommended to reset the alarm automatically
by external sequence, etc.
