Safety advice
2Basic - Information
2.1 Safety advice
Electronic equipment is not fault proof.
Attention – High voltage
360-550V~, 450-550V=
Shock hazard / Danger of life!!
Before installation or commissioning begins, this manual must be thoroughly read and
understood by the technical staff involved.
The devices are electrical equipment (EB) to the power electronics for the control of power flow
in electrical power systems.
Protection rating IP00.
Control and power connections can
voltage lead, works without the drive!
Measured before disassembly voltage!
2.2 Standards and guidelines:
The device and its associated components can only be installed and switched on where the local
regulations and technical standards have been strictly adhered to:
EU Guidelines:
2004/108/EG, 2006/95/EG, 2006/42/EG
EN 60204-1, EN292, EN50178, EN60439-1,

Q3 240-840A
Standards and guidelines:
The user must ensure that in the event of:
- device failure
- incorrect operation
- loss of regulation or control
the axis will be safely de-activated.
It must be ensured that the machines, equipment or vehicles are
fitted with device independent monitoring and safety feature.
Non-earthed systems (e.g. vehicles) need to be secured isolation
monitors.
There must be no danger to persons and property arising!
Assembly
- should only be carried out when all voltages have been removed and the units are secured
- should only be carried out by suitably trained personnel
Installation
- should only be carried out when all voltages have been removed and the units are sucured
- should only be carried out by suitably trained personnel for electrics
- should only be carried in accordance with health and safety guidelines
Adjustments and programming
- should only be carried out by suitable trained personnel with knowledge in electronic drives
and their software
- should only be carried out in accordance with the programming advice
- should only be carried in accordance with health and safety guidelines
CE
When mounting the units into machines and installations the proper operating of the units may
not be started until it is ensured that the machine, the installation, or the vehicle comply with the
regulations of the EC machinery directive 2006/42/EG and the EMC guideline 2004/108/EG.
On the installation and test conditions described in the chapter CE-advice it is adhered to the EC
guideline 2004/108/EG including the EMC standards EN61000-2 and EN61000-4.
A manufacturer’s declaration can be requested.
The manufacturer of the machine or installation is responsible for observing the threshold values
demanded by the EMC laws.
QS
The devices are archived with serial number and the test data from the manufacturer for 5 years.
The inspection reports may be requested.

General and features
2.3 General and features
This manual describes the basic unit and
is only in connection with the manual of the control electronics
(e.g. REGxx) valid.
Manual use in connection with:
- an analogue control REGxx
- field regulation internal QS-F
- field regulation external F2xx
- options
Build
- switch cabinet mounting a
- according to the VDE, DIN and EU regulations
- standard control electronics REG
- intrinsically safe power section with current control loop
- controlled or uncontrolled field supply unit
- optional units
Galvanic isolation between
