Terminal 37 is used for Safe Torque Off (STO). For STO installation instructions, refer to the VLT® Frequency Converters - Safe Torque
Off Operating Guide.
Long control cables and analog signals may in rare cases, depending on installation, result in 50/60 Hz ground loops due to noise
from mains supply cables. If 50/60 Hz ground loops occur, consider breaking the shield or insert a 100 nF capacitor between shield
and enclosure.
To avoid ground currents from both groups to affect other groups, connect the digital and analog inputs and outputs separately to
the common inputs (terminals 20, 55, and 39) of the drive. For example, switching on the digital input may disturb the analog input
signal.

2 Safety Instructions
2.1 Overview
This Safety chapter only relates to programming the drive. When installing or operating the drive, refer to the Installation Guide
applicable safety instructions. To programming this product safely:
Never program damaged units.
Follow the instructions provided in this Programming Guide.
Make sure that all personnel working on or with the drive have read and understood this guide and any additional product
manuals. Contact if you are unclear of the given information, or if you lack information.
2.2 Target Group and Necessary Qualifications
Correct and reliable transport, storage, installation, operation, and maintenance are required for the trouble-free and safe operation
of the drive. Only skilled personnel are allowed to perform all related activities for these tasks. Skilled personnel are defined as
properly trained staff, who are familiar with and authorized to install, commission, and maintain equipment, systems, and circuits in
accordance with pertinent laws and regulations. Also, the skilled personnel must be familiar with the instructions and safety meas-
ures described in this manual and the other product-specific manuals. If you are not a skilled electrician, do not perform any electri-
cal installation and troubleshooting activities.
2.3 Safety Symbols
The following symbols are used in this manual:
DANGER
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION

2.4 General Safety Precautions
WARNING
HAZARDOUS VOLTAGE
AC drives contain hazardous voltage when connected to the AC mains or connected on the DC terminals. Failure to perform
installation, start-up, and maintenance by skilled personnel can result in death or serious injury.
Only skilled personnel must perform installation, start-up, and maintenance.
WARNING
DISCHARGE TIME
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be
present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work can result in death or
serious injury.
Stop the motor.
Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and
DC-link connections to other drives.
Wait for the time specified in the Discharge Time tables for the capacitors to discharge fully before performing any service or
repair work.
Measure the voltage level to verify full discharge.

CAUTION
HOT SURFACES
The drive contains metal components that are still hot even after the drive has been powered off. Failure to observe the high
temperature symbol (yellow triangle) on the drive can result in serious burns.
Be aware that internal components, such as busbars, may be extremely hot even after the drive has been powered off.
Do not touch exterior areas that are marked by the high temperature symbol (yellow triangle). These areas are hot while the
drive is in use and immediately after being powered off.

2.5 Lifting the Drive
NOTICE
LIFTING HEAVY LOAD
The weight of the drive is heavy and failure to follow local safety regulations for lifting heavy weights may cause death, personal
injury, or property damage.
Ensure that the lifting equipment is in proper working condition.
Check the weight of the drive and verify that the lifting equipment can safely lift the weight.
Always lift the drive using a lifting bar inserted into the lifting eyes. Maximum diameter for the lifting bar: 20 mm (0.8 in).
The angle from the top of the drive to the lifting cable: 60° or greater.
Test lift the unit approximately 610 mm (24 in) to verify the proper center of gravity lift point. Reposition the lifting point if
the unit is not level.

2.6 Mechanical Installation Precautions
WARNING
EXPLOSIVE ATMOSPHERE
Installing the drive in a potentially explosive atmosphere can lead to death, personal injury, or property damage.
Install the unit in a cabinet outside of the potentially explosive area.
Use a motor with an appropriate ATEX protection class.
Install a PTC temperature sensor on an ATEX PTC-Thermistor device to monitor the motor temperature.
Install short motor cables.
Use sine-wave output filters when shielded motor cables are not used.
2.7 Safe Operation
When operating the unit, refer to the Programming Guide and Application Guide for guidance and all applicable safety instructions.
The drive is not suitable as the only safety device in the system. Make sure that additional monitoring and protection devices on
drives, motors, and accessories are installed according to the regional safety guidelines and accident prevention regulations.
Keep all doors, covers, and terminal boxes closed and securely fastened during operation.
