The DC bus circuit or the mains supply must always be switched off prior to switching off
the 24V controller supply.
Carry out work in the machine area only, if AC and/or DC supplies are switched off.
Switched off output stages or controller enablings are no suitable means of locking. In
the case of a malfunction the drive may accidentally be put into action.
Initial operation must be carried out with idle motors, to prevent mechanical damages
e.g. due to the wrong direction of rotation.
Electronic devices are never fail-safe. It is the user’s responsibility, in the case an
electrical device fails, to make sure the system is transferred into a secure state.
The servo drive controller and in particular the brake resistor, externally or internally, can
assume high temperatures, which may cause serious burns.
Protection against contact with electrical parts
This section only concerns devices and drive components carrying voltages exceeding 50 V. Contact
with parts carrying voltages of more than 50 V can be dangerous for people and may cause electrical
shock. During operation of electrical devices some parts of these devices will inevitably carry
dangerous voltages.
DANGER!
High electrical voltage!
Danger to life, danger due to electrical shock or serious personal injury!
The appropriate DIN, VDE, EN and IEC regulations as well as all national and local safety regulations
and rules for the prevention of accidents apply for the assembly and maintenance of the system. The
plant engineer or the operator is responsible for compliance with these regulations:
Before switching on the device, install the appropriate covers and protections against
accidental contact. Rack-mounted devices must be protected against accidental contact
by means of a housing, e.g. a switch cabinet. The regulations VGB4 must be complied
with!
Always connect the ground conductor of the electrical equipment and devices securely to
the mains supply.
Comply with the minimum copper cross-section for the ground conductor over its entire
length as per EN60617!
Prior to the initial operation, even for short measuring or testing purposes, always
connect the ground conductor of all electrical devices as per the terminal diagram or
connect it to the ground wire. Otherwise the housing may carry high voltages which can
cause electrical shock.
