Dangerous voltage warning
warns of high voltage
which can cause physical injury and/or damage to
the equipment.
General danger warning
warns about conditions,
other than those caused by electricity, which can
result in physical injury or death and/or damage to
the equipment.
Electrostatic sensitive discharge warning
warns of
electrostatic discharge which can damage the
equipment.
Installation and maintenance work
Warning
•
Only qualified electricians are allowed to install
and maintain the drive!
•
Apply always the five safety rules
•
Never work on the drive, motor cable or motor
when main power is applied.
•
Do not work on the control cables when power is
applied to the drive or to the external control
circuits. Externally supplied control circuits may
cause dangerous voltages inside the drive even
when the main power on the drive is switched off.
Grounding
Warning
•
Ground the drive, motor and adjoining equipment
to ensure personnel safety in all circumstances,
and to reduce electromagnetic emission and
pick-up.
•
Make sure that grounding conductors are
adequately sized and marked as required by safety
regulations.
Notes:
•
Power cable shields are suitable as equipment
grounding conductors only when adequately sized
to meet safety regulations.
•
This product can cause a DC current in the
protective earthing conductor. Where a residual
current-operated protective (RCD) or monitoring
(RCM) device is used for protection in case of
direct or indirect contact, only an RCD or RCM of
Type B is allowed on the supply side of this
product.
Mechanical installation
These notes are intended for all who install the drive. Handle
the unit carefully to avoid damage and injury.
Warning
•
DCS880 sizes H4 ... H8:
- The drive is heavy. Lift the drive by lifting lugs
only.
- The drive’s center of gravity is high. Do not tilt
the unit. The unit will overturn from a tilt of
about 6 degrees. An overturning drive can cause
physical injury.
- Do not lift the unit by the front cover.
-
Place units H4 … H6 only on their back.
•
Make sure that dust from drilling does not enter
the drive when installing. Electrically conductive
dust inside the unit may cause damage or lead to
malfunction.

Safety instructions, drives commisioning
•
Ensure sufficient cooling.
•
Do not fasten the drive by riveting or welding.
Operation
Warning
•
Before adjusting the drive and putting it into
service, make sure that the motor and all driven
equipment are suitable for operation throughout
the speed range provided by the drive.
•
EMERGENCY STOP buttons must be installed at
each control desk and at all other control panels
requiring an emergency stop function. Pressing the
STOP button on the control panel of the drive will
neither cause an emergency stop of the motor, nor
will the drive be disconnected from any dangerous
potential.
•
To avoid unintentional operating states, or to shut
the unit down in case of any imminent danger
according to the standards in the safety
instructions it is not sufficient to merely shut down
the drive via signals "RUN", "drive OFF" or
"Emergency Stop" respectively "control panel" or
"PC tool".
Note:
•
When the control location is not set to Local (Local
not shown in the status row of the display), the
stop key on the control panel will not stop the drive.
To stop the drive using the control panel, press the
Loc/Rem key and then the stop key
.
NEC motor overload protection
The DCS800 provides a solid-state motor overload
protection in accordance with the NEC. The overload
protection (e.g. protection level in percent of full-load motor
current) can be adjusted by parameters in group 31 and
group 99.
The instructions can be found in chapter Motor thermal
model of the DCS800 Firmware manual.
General instructions
•
This short commissioning refers to Chapter 5 Connection
examples of this publication.
•
Safety and operating instructions - see chapter 6 of this
publication.
•
In accordance with DIN 57 100 Part 727 / VDE 0100 Part
727, precautions must be taken to enable the drive to be
shut down, e.g. in the event of danger.
The unit’s digital inputs or the control panel are not
sufficient as the sole measure for this purpose!
