You Should Pay Attention To This - Kollmorgen SERVOSTAR 300 Manual

2.3.2 You should pay attention to this

Read the documentation!
Read the available documentation before installation and commissioning. Improper handling
of the devices can cause harm to people or damage to property. The operator must therefore
ensure that all persons entrusted to work on the devices have read and understood the
manual and that the safety notices in this manual are observed.
Always observe the whole drive system built with servo amplifier, cables, motor, accessor-
ies (filters, chokes, etc.). This means, that all documentation which exist for the com-
ponents, must be available, must be read and must be understood.
Pay attention to the technical data!
Adhere to the technical data and the specifications on connection conditions (rating plate and
documentation). If permissible voltage values or current values are exceeded, the devices
can be damaged, e.g. through overheating.
Specialist staff required!
Only properly qualified personnel are permitted to perform such tasks as transport,
assembly, setup and maintenance. Qualified specialist staff are persons who are familiar
with the transport, installation, assembly, commissioning and operation of power electronics
and who bring their relevant minimum qualifications to bear on their duties. The qualified per-
sonnel must know and observe IEC 60364 / IEC 60664 and national accident prevention reg-
ulations.
Additional requirements on specialist staff may also result from the risk assessment.
Hot surface!
Some devices can reach temperatures of up to 250°C during operation. Touching them can
result in burns. Observe the permissible mounting position and ensure that a sufficient dis-
tance is maintained from neighboring assemblies.
Earthing!
It is vital that you ensure that the device housing is safely earthed to the PE (protective
earth) busbar in the switch cabinet. Without low-resistance earthing no personal protection
can be guaranteed and there is a risk of death from electric shock.
High voltages!
Keep the switching cabinet closed when the equipment is in operation. Not having optical dis-
plays does not guarantee an absence of voltage. Power connections may carry voltage even
if the motor is not turning.
Do not unplug any connectors during operation. There is a risk of death or severe injury from
touching exposed contacts. Power connections may be live even when the motor is not rotat-
ing. This can cause flashovers with resulting injuries to persons and damage to the contacts.
DC Bus link connections can carry dangerous voltage levels over an hour after the line
voltage has been switched off (self-discharge time). Danger of death from electric shock.
Before commencing work on the modules' power terminals, check the voltage at the con-
nection terminals is de-energized to ground and to each other.
