warning
The symbol is identied by a yellow background, black triangular band, and a black rotating rotor

symbol. It indicates strong
rotating rotor that could cause harm to a person or property.
General Information
Read the instructions in the manual
Personal protective equipment
Personal protective equipment shall be used when necessary during handling, installation and
maintenance of the electric machine to avoid injury.
Use eye protective equipment like safety goggles or mask when you work

with the electric device.

Permanent damage to the eye
could be caused if bearing grease, melted nitrile rubber (radial lip seal), glycol or other uids splash.
Use hearing protective equipment when you work

on the electric machine.

Hearing injuries can

be caused by too loud noise
(noise in excess of 85 dBA).
Use head protective equipment like helmet when you lift

the electric machine! Head injuries can

be caused by object impact.
Use cut resistant gloves when you

handle

and maintain

the electric machine.

There is a risk of cut injuries.
Use protective footwear when you lift

or move

the electric machine! Foot injuries could be caused if lifting system or lifting
brackets fail.
Security features
The electric machines have at least three PT100 temperature sensors in the windings. The amount
of the sensors depend on the options chosen. The temperature signal(s) can be read out from the
measurement connector of the electric machine. You can connect the temperature signal to the
temperature surveillance pin in the inverter (EC-C) and make sure that the inverter has the
machine temperature protection feature activated.
Electromagnetic compatibility (EMC)
When interfacing other equipment, connect only equipment that are specied as part of the system and that
are

compatible.
Magnetic and electromagnetic elds generated near the current-carrying conductors and permanent magnets in electric
machines represent a health danger to persons with heart pacemakers, metal implants and hearing aids
.
Persons with a
heart pacemaker, metal implants or hearing aids must consult a doctor before they enter the following areas:
Areas in which electric equipment and parts are operated
Areas in which electric equipment with permanent magnets are stored, mounted, operated or repaired
If necessary, perform a special electromagnetic compatibility (EMC) test on the installation
.

EMC stands for Electromagnetic compatibility. It is the ability of electric equipment to operate
without problems within an electromagnetic environment. Likewise, the equipment must not
disturb or interfere with any other product or system within its locality. This is a legal requirement
for all equipment taken into service within the European Economic Area (EEA).
Our products are designed with high standards of EMC in mind. Connect the power lines and
groundings along the instructions in this manual to achieve the required level of EMI

protection.
It is the responsibility of the installer to ensure that the equipment or system into which the
product is incorporated complies with the EMC legislation of the country of use. Within the
European Union, equipment into which this product is incorporated must comply with the EMC
Directive 2004/108/EC.
