Electrical Connection - YASKAWA Varispeed E7 Manual De Instrucciones

Varispeed E7
Installation
Install and cool the inverters as specified in the documentation. The cooling air must flow in the
specified direction. The inverter may therefore only be operated in the specified position (e.g.
upright). Maintain the specified clearances. Protect the inverters against impermissible loads. Com-
ponents must not be bent nor insulation clearances changed. To avoid damage being caused by
static electricity, do not touch any electronic components or contacts.

Electrical Connection

Carry out any work on live equipment in compliance with the national safety and accident preven-
tion regulations. Carry out electrical installation in compliance with the relevant regulations. In par-
ticular, follow the installation instructions ensuring electromagnetic compatibility (EMC), e.g.
shielding, grounding, filter arrangement and laying of cables. This also applies to equipment with
the CE mark. It is the responsibility of the manufacturer of the system or machine to ensure confor-
mity with EMC limits. Your supplier or Yaskawa representative must be contacted when using leak-
age current circuit braker in conjunction with frequency inverters.
In certain systems it may be necessary to use additional monitoring and safety devices in compli-
ance with the relevant safety and accident prevention regulations. The frequency inverter hardware
must not be modified.
Caution!
Cables must not be connected or disconnected, nor signal tests carried out, while the power
➔
is switched on.
Do not perform a withstand voltage test on any part of the Varispeed. The frequency inverter
➔
contains semiconductors, which are not designed for such high voltages.
Do not remove the digital operator while the mains supply is switched on. The printed circuit
➔
board must also not be touched while the inverter is connected to the power.
Never connect general LC/RC interference suppression filters, capacitors or overvoltage pro-
➔
tection devices to the inverter input or output.
To avoid unnecessary over current faults, etc, being displayed, the signal contacts of any con-
➔
tactor or switch fitted between inverter and motor must be integrated into the inverter control
logic (e.g. baseblock).
Please do not connect or operate any equipment with visible damage or missing parts. The
➔
operating company is responsible for any injuries or equipment damage resulting from failure
to heed the warnings in this manual.
A complete manual on CD-ROM is included within this package. A paper copy can be printed
directly from this CD-ROM. Of course a printed copy can be ordered from a local sales office or
also from our web site http://www.yaskawa.de.
Notes
The VARISPEED E7 frequency inverters are certified to CE, UL, and c-UL.
Note!
For equipment destined to the U.S. and Canadian markets, specific installation requirements and/
or recommendations are specified and are referred to in full detail in the full version of the instruc-
tion manual contained on the CD included with this product. It is recommended that a hard copy of
this full version instruction manual be provided with the product before delivery to the U.S. and
Canadian markets.
