General information
The NORDAC trio SK 300E can be used in hazardous areas with a suitable modification. It is important that all
safety information given in the operating instructions are strictly complied with for person and property reasons.
This is essential to avoid hazards and damage.
Qualified personnel
It is assumed that all work regarding transport, mounting, installation, commissioning and maintenance is
carried out by qualified personnel. Qualified personnel are those persons who, based on their education,
experience, training and knowledge of applicable standards, specifications, accident prevention regulations
and operating conditions, are authorised to implement the relevant activities required to commission the
frequency inverter. In addition, knowledge of first aid measures and the local rescue facilities is necessary.
ATTENTION
All work must be carried out only when the system is in an electrically voltage-free state.
If the frequency inverter is connected to a motor and a gear, the Ex designations of the motor and
gear must also be taken into account!
Safety information
The increased danger in areas with combustible dust requires that the general safety and commissioning
instructions are strictly complied with. The drive must comply with the specifications in the Project outline No.
6052101
. Explosive dust concentrations can cause explosions if ignited by hot or sparking objects and this can
cause severe or even lethal injuries to persons and significant damage to property.
It is absolutely essential that the persons authorised to use these motors and frequency inverters in hazardous
areas are trained in their correct use.
ATTENTION The mains voltage must always be switched off and secured against being switched on again
before opening the frequency inverter to connect the electrical lines or any other work!
Higher temperatures than the maximum permitted surface temperature of the enclosure may be
present inside the frequency inverter and motor. The frequency inverter must therefore never be
opened in hazardous dust atmospheres or removed from the motor!
Unpermitted high dust deposits may not be allowed to build up as they restrict the cooling of the
frequency inverter!
Note: Repairs must only be carried out by Getriebebau NORD.
