Isolate the drive converter from the mains before removing the terminal cover or the hous-
ing (e.g. by removing or deactivating on-site fuses or by deactivating a master switch iso-
lating all poles etc.).
After disconnection of the drive converters from the voltage supply, live appliance parts and
power terminals must not be touched immediately because of possibly energized capaci-
tors. In this respect, the corresponding signs and markings on the drive converter must be
respected. After switching off the mains voltage, wait for at least 5 minutes before begin-
ning work on or in the drive converter. Dangerous voltages are still present as long as the
“STATUS” lamp is still lit. In the event of malfunctions, the discharge time of 5 minutes may
be exceeded substantially.
The drive converter contains protective facilities that deactivate it in the event of malfunc-
tions, whereby the motor is de-energized and comes to a standstill (so-called “coasting” of
the motor is possible depending on the rotating mass of the type of drive involved). Stand-
still of the motor can, however, also be produced by mechanical blockage. Voltage fluctua-
tions, and particularly mains power failures, may also lead to deactivation. In certain
circumstances, the drive may start up automatically once the cause of the fault has been
remedied. As a result of this, certain systems may be damaged or destroyed and there may
be a risk for operators working on the system. Installations which include drive converters
shall be equipped with additional control and protective devices in accordance with the rel-
evant applicable safety requirements, e.g. Act respecting technical equipment, accident
prevention rules etc. Changes to the drive converters by means of the operating software
are admissible.
The motor may be stopped during operation by disabling it or by deactivating the setpoint,
whereby the drive converter and motor may remain live. If inadvertent start-up of the mo-
tor must be excluded to protect operating personnel, electronic interlocking by dis-
abling the motor or by deactivating the setpoint is inadequate. This is why the drive
converter must be isolated from the mains voltage.
During operation, all covers and doors shall be kept closed.
Measuring instruments must be connected and disconnected only in de-energized condi-
tion.
Unauthorized conversions or modifications on or in the drive converter and its components
and accessories will render all warranty claims void.
Please contact BERGES if conversions or modifications are necessary, particularly if elec-
trical components are involved.
7. Maintenance and Servicing
The manufacturer's documentation shall be followed.
KEEP SAFETY INSTRUCTIONS IN A SAFE PLACE!
1.3 Preface
The present manual contains the specifications, installation instructions, description of op-
eration and troubleshooting procedures for ACP 3000 inverters. The information in this
manual must be known before installation of the inverter in order to guarantee fault-free in-
stallation and thus maximum performance.
Before you read on, please check whether technical changes are at-
tached in the annex to this operating manual!
