AC motor controls and servo drives contain dangerous voltages which
can cause death or serious injury. During operation they can have live
"energized" un-insulated parts, moving parts, as well as hot surfaces.
Care should be taken to ensure correct and safe operation in order to
minimize risk to personnel and equipment.
All work involving this product, installation, start up as well as mainte-
nance, may only be performed by qualified electrical technical person-
nel. According to this manual "qualified" means: those who are able to
recognize and acknowledge the possible dangerous conditions based
on their training and experience and those who are familiar with the
relevant standards and installation codes as well as the field of power
transmission.
AC motor controls and servo drives must be protected against physical
damage during transport, installation, and use. Components or covers
must not be bent or deformed as this may decrease insulation distances
inside the unit resulting in an unsafe condition. On receipt of the unit
visual damage should be reported immediately to the supplier. DO NOT
ATTEMPT TO POWER UP A UNIT WITH VISIBLE PHYSICAL DAMAGE.
This unit contains electrostatically sensitive components which can
be destroyed by incorrect handling. For that reason, disassembly of the
unit or contact with the components should be avoided.
Before any installation and connection work can be done, the supply
voltage must be turned off and locked out. After turning off the supply
voltage, dangerous voltages may still be present within the unit as the
bus capacitors discharge. Therefore it is necessary to wait 5 minutes
before working on the unit after turning off the supply voltage.
The low voltage control terminal strip and communication ports are se-
curely isolated in accordance with EN50178. When connecting to other
systems, it is necessary to verify the insulation ratings of these sys-
tems in order to ensure the EN requirements are still met. When con-
necting the unit to a grounded delta power system, the control circuit
can no longer be classified as a "securely isolated circuit".
Before putting the motor control into operation be sure the connection
terminals are tight and all covers removed for installation have been
replaced.
The AC motor control or servo system can be adjusted to self initiate an
automatic restart in the event of a fault or error condition. The design
of the system must take this into account, such that personnel are safe
guarded against potentially dangerous circumstances.
Software functions in the AC motor control or servo system can be used
to control or regulate external systems. However, in the event of failure
of the motor control or servo system there is no guarantee these soft-
ware function(s) will continue to provide the desired level of control. As
a result, when operator or machine safety is at stake, external elements
must be used to supplement or override the software function within the
AC motor control or servo system.
