Safety Instructions
General
R4-S-regenerative units contain dangerous voltages which can cause death or
serious injury. Care should be taken to ensure correct and safe operation to
minimise risk to personal and equipment.
If connected inverter at the R4-S-regenerative unit are running regenerative,
and the turn-off time of the R4-S-regenerative unit (parameter Pn.59) is adjusted
> 0 s, dangerous high voltage will be supplied to the terminals of the R4-S-
regenrative unit during mains failure. Therefore a dangerous high voltage for the
time of Pn.59 can still be in the system, even after the power supply system is
switched off.
Before any working with the unit, control the safe isolation from supply. (with
measurements in the unit).
All work from the transport, to installation and start-up as well as maintenance
may only be done by qualified personnel (IEC 364 and/or CENELEC HD 384
(VDE 0100) and note national safety regulations). According to this manual
qualified staff means:
- those who are able to recognise and judge the possible dangers based on
their technical training and experience
- those with knowledge of the relevant standards and who are familiar with the
field of power trasmission (EN 50178 (VDE 0100 VDE 0160, EN 60204 (VDE
0113)) as well as the approporiate regulations for your area.
Use as directed
R4-S-regenerative units serves for teeding back energy from the DC-bus circuits
of frequency inverters.
Operation with R4-S-regenerative units is only allowed in connection with
frequency inverters. Connection of other electrical consumer of the R4-S-rege-
nerative units is not allowed and the unit can be destroyed .
The R4-S-regenerative unit must not be started until it is determined that the
installation complies with 89/392/EEC (machine directive) as well as the EMC-
directive 89/336/EEC.
The regenerative units meet the requirements of the Low-Voltage Directive 73/
231/EEC. The harmonized standards of the series EN 50178
(VDE 0160) in connection with EN 60439-1 (VDE 0660 Part 500) and
EN 60146 (VDE 0558) were used.
Transport and Storage
The R4-S-regenerative units must be protected against physical damage during
transport, installation and use. Components and covers must not bent or moved
as this may affect insulation distances.
