II.2 Installation
Only professional staff who are qualified in electrical engineering are allowed to install
the transistor controller.
The installation procedure is described as an example. A different procedure may be sensible or
necessary, depending on the application of the equipment.
We provide further know-how through training courses (on request).

Warning !
Protect the transistor controller from impermissible stress.
In particular, components must not be bent or insulation distances altered dur
-
ing transport and handling.
Avoid touching electronic components and contacts.
Caution !
Only install and wire up the equipment when it is not live, i.e. when neither the
mains power supply nor the operating voltages of any other connected equip
-
ment is switched on. Take care that the switchgear cabinet is safely discon
-
nected (with a lockout, warning signs etc.).
The individual voltages will be switched on for the first time during commission
-
ing.
Ground and PE symbols
The ground symbol
X , which you will find in all the wiring diagrams, indicates
that you must take care to provide an electrically conductive connection with
the largest possible area between the component indicated and the mounting
plate in the switchgear cabinet. This connection is for the effective grounding of
HF interference. It must not be confused with the PE symbol W (protective meas
-
ure to EN 60204) .
Grounding system and protective earthing
The DC-link circuit is earthed on one side, and supplied from the mains via an
isolating transformer which has a screen winding.
The reference potentials 0V/GND/PE (DC-link –) and AGND (control electronics)
are connected inside the instrument, for functional reasons.
The central connection to PE is made on the back-panel.
