Note
It is not permissible to connect SIMODRIVE equipment to a supply system with
ELCBs (this restriction is permitted acc. to DIN VDE 0160/05.88, Section 6.5).
When operational, protection against direct contact is provided in a form to al-
low the unit to be used in enclosed electrical equipment rooms
(DIN VDE 0558 Part 1/07.87, Section 5.4.3.2.4).
In compliance with DIN VDE 0160/05.88, all SIMODRIVE units are subject to a
high–voltage test at the time of routine testing. If the electrical equipment of
industrial tools is subject to a high–voltage test, all connections must be discon-
nected so that sensitive electronic components in the SIMODRIVE converter
are not damaged (permissible according to DIN VDE 0113/06.93, Part 1,
Section 20.4).
Warning
!
Start–up/commissioning is absolutely prohibited until it has been ensured that
the machine in which the components described here are to be installed, fulfills
the regulations/specifications of the Directive 89/392/EWG.
Warning
!
The information and instructions in all of the documentation supplied and any
other instructions must always be observed to eliminate hazardous situations
and damage.

The holding brake is only designed for a limited number of emergency braking
operations. It is not permissible to use it as working brake.
iv
For special versions of the machines and equipment, the information in the
associated catalogs and quotations applies.
Further, all of the relevant national, local and plant/system–specific regula-
tions and specifications must be taken into account.
All work should be undertaken with the system in a no–voltage condition!
For the feed motors, when the rotor is rotating, a voltage is present at the
motor terminals (as a result of the integrated permanent magnets).
The motor must be connected according to the circuit diagram supplied.
It is not permissible to directly connect the motor to the three–phase supply
as this would destroy the motor.
Surface temperatures of above 100
surface. No temperature–sensitive parts or components, e.g. cables or
electronic components may be in contact with or connected to the motor.
