DANGER
There is a danger of electrical arcing which can cause serious personnel
injury. Only install and wire the equipment when it is not live, that is, when
neither the electrical supply nor the 24 V auxiliary voltage nor the supply
voltages of any other connected equipment is switched on.
Make sure that the cabinet is safely disconnected (for instance, with a
lock-out and warning signs). The individual voltages are switched on for
the first time during setup.
The built-in LED does
not
safely indicate the real voltage level. Always
measure the voltage in the DC bus link at connector X14 at AKD-C and
wait until the voltage is below 60 V before handling any component in the
decentral servo system.
Only professional staff who are qualified in electrical engineering are allowed to install the
drive. Wires with color green with one or more yellow stripes must not be used other than for
protective earth (PE) wiring.
The ground symbol, which you will find in all the wiring diagrams, indicates that you must
take care to provide an electrically conductive connection with the largest feasible surface
area between the unit indicated and the mounting plate in the control cabinet. This connection
is for the effective grounding of HF interference, and must not be confused with the PE-sym-
bol (PE = protective earth, safety measure as per IEC 60204).
