5 Commissioning
134 BA8230
5.1 Safety instructions The user must be familiar with handling the software (section 4) before
for commissioning commissioning the unit.
Electrical equipment represents a source of risk.
The units described here carry dangerous voltages and control rotating mechanical
parts. Death, severe physical injury and extensive material damage may result if
these instructions are not followed.
Dangerous voltages of over 1000 V which can cause death or severe physical injury
can occur during operation of these units. Extreme caution is essential when working
on the unit. Please therefore note the following warnings.
Covers must remain installed during normal operation.
The conditions of VBG4 paragraph 2(2) must be observed for adjustment work during
operation with the unit open.
Stand on an insulated mat (compliant with EGB) and ensure it is not earthed if you are
carrying out commissioning work when the unit is switched on.
Do not use any technical equipment unless you are certain it is in perfect condition
and undamaged.
If an oscilloscope is used, it must be powered through an isolating transformer to
prevent earth loops. The oscilloscope casing must be connected directly to the 8230
frequency inverter reference potential.
Test equipment such as oscilloscope probes, terminals etc. may only be fitted in the
de-energised condition and taking potential compensation of electronics modules into
consideration.
Correct implementation of the commissioning instructions on a step-by-step basis as
stated in this manual will help prevent damage. Contact our Service Department if you
require any further information.
Incorrect parameter adjustments and type data can damage the equipment and the
complete drive. Set all parameters with extreme care and also note section 4.
Printed circuit boards and all plug connections may only be inserted or removed in the
de-energised condition. This is the only way to avoid destruction of entire assemblies
and risk to personnel.
Avoid touching any electronic modules. If this is not possible, discharge any static
electricity immediately beforehand.
