Introduction

1.6 Safety

The following symbols are used in this guide:
WARNING
Indicates a potentially hazardous situation that could
result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that could
result in minor or moderate injury. It can also be used to
alert against unsafe practices.
NOTICE
Indicates important information, including situations that
can result in damage to equipment or property.
The following safety instructions and precautions relate to
®
the VLT Integrated Servo Drive ISD
Read the safety instructions carefully before starting to
work in any way with the ISD 510 servo system or its
components.
Pay particular attention to the safety instructions in the
relevant sections of this manual.
WARNING
HAZARDOUS SITUATION
If the servo drive, SAB, or the bus lines are incorrectly
connected, there is a risk of death, serious injury, or
damage to the unit.
•
Always comply with the instructions in this
manual and national and local safety
regulations.
WARNING
GROUNDING HAZARD
The ground leakage current is >3.5 mA. Improper
grounding of the ISD 510 servo system components may
result in death or serious injury.
•
For reasons of operator safety, ground the
components of the ISD 510 servo system
correctly in accordance with national or local
electrical regulations and the information in this
manual.

WARNING
HIGH VOLTAGE
The ISD 510 servo system contains components that
operate at high voltage when connected to the electrical
supply network.
A hazardous voltage is present on the servo drives and
the SAB whenever they are connected to the mains
network.
There are no indicators on the servo drive or SAB that
indicate the presence of mains supply.
Incorrect installation, commissioning, or maintenance can
lead to death or serious injury.
•
Installation, commissioning, and maintenance
must only be performed by qualified personnel.
WARNING
UNINTENDED START
The ISD 510 servo system contains servo drives and the
SAB that are connected to the electrical supply network
and can start running at any time. This may be caused
by a fieldbus command, a reference signal, or clearing a
fault condition. Servo drives and all connected devices
must be in good operating condition. A deficient
operating condition may lead to death, serious injury,
damage to equipment, or other material damage when
the unit is connected to the electrical supply network.
•
Take suitable measures to prevent unintended
starts.
WARNING
UNINTENDED MOVEMENT
Unintended movement may occur when parameter
changes are carried out immediately, which may result in
death, serious injury, or damage to equipment.
•
When changing parameters, take suitable
measures to ensure that unintended movement
cannot pose any danger.
