ARTDrive V2 series - Instruction Manual Chapter 0 Safety Precautions • 0-11
- 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.
- 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.
- Do not perform a megger test between the Drive terminals or on the
control circuit terminals.
- 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 104° F (40° C) or below.
- If the Drive’s Fault Alarm is activated, consult the chapter 8,
TROUBLESHOOTING, and after correcting the problem, resume
operation. Do not reset the alarm automatically by external sequence,
etc.
- Be sure to remove the desicant dryer packet(s) when unpacking the
Drive. (If not removed these packets may become lodged in the fan
or air passages and cause the Drive to overheat).
- The Drive must be mounted on a wall that is constructed of heat
resistant material. While the Drive is operating, the temperature of
the Drive's cooling fins can rise to a temperature of 194° F (90°C).
- Do not touch or damage any components when handling the device.
Changing of isolation gaps or removing the isolation covers is not
permissible.
- Protect the device from disallowed environmental conditions
(temperature, humidity, shock etc.)
- No voltage should be connected to the output of the frequency inverter
(terminals U2, V2 W2). The parallel connection of several frequency
inverters via the outputs and the direct connection of the inputs and
outputs (bypass) are not permissible.
- A capacitative load (e.g. Var compensation capacitors) should not be
connected to the output of the frequency inverter (terminals U2, V2,
W2).
- The electrical commissioning should only be carried out by qualified
personnel, who are also responsible for the provision of a suitable
ground connection and a protected power supply feeder in
accordance with the local and national regulations. The motor must
be protected against overloads.
- No dielectric tests should be carried out on parts of the frequency
inverter. A suitable measuring instrument (internal resistance of at
least 10 k
ΩΩ
ΩΩ
Ω/V) should be used for measuring the signal voltages.
- Ne pas raccorder de tension d’alimentation dépassant la fluctuation de
tension permise par les normes.
Dans le cas d’ une alimentation en tension excessive, des composants
internes peuvent être endommagés.
