General Safety Precautions

Danger!
During assembly, commissioning, maintenance and inspection, make sure all parts and any areas required for
preparation are inaccessible to unauthorized persons
• In spite of all precautions, there will always be some element of risk that cannot be entirely excluded, whether due
to human error, malfunction of the device, or force majeure. The system planner, operator or engineer must take all
precautions deemed necessary, as outlined in EN 12100, to prevent a hazardous situation from arising.
• Make sure general rules and regulations for occupational safety are observed.
• Make sure the fan is accessible for servicing and maintenance.
• Assembly and electrical installation must be carried out by trained technicians working in accordance with all rele-
vant regulations.
• All electrical connections must be made by a qualifi ed electrician. Make sure the equipment is disconnected from
power before any maintenance or repair work begins.
• Make sure the fan cannot be inadvertently switched on and the impeller cannot be inadvertently accessed while
any work is being performed on the fan.
• The housing of the fan must not be damaged or deformed during assembly.
• Make sure there is no risk of contact with the impeller during operation of the fan.
• To prevent equipment failure and to protect the motor, the motor must be disconnected from the power supply
(mains) by a built-in PTC resistor in the event of any operational disorder (for example, median temperature higher
than permitted maximum) in accordance with Council Directive 94/9/EC.
• Maximum test voltage for the PTC resistor: 2.5 V.
• The motors contain triple PTC resistors. More than two PTC resistors must not be connected in series, because this
can lead to undefi ned shutdown.
• Be sure to wear protective goggles when checking the rotation direction of the impeller.
• Parts that are relevant to safety, such as the safety guard in front of the impeller, must not be removed nor put out
of operation. Furthermore, such parts must be checked for tight attachment.
• Compliance with EMC Council Directive 89/336/EEC applies to this product only if it is directly connected to the
conventional electric power system (mains). If the product is integrated in a system or combined and operated with
other components (such as controllers or process control modules), the manufacturer or operator of the overall
system is responsible for ensuring compliance with EMC Council Directive 89/336/EEC.
• The nameplate indicates the electrical values for the optimally cooled motor approved by the notifi ed body in the
EC type examination (Declaration of Conformity).
• Prevent the intake of foreign bodies as these can damage the fan.
• Even inlet and unobstructed inlet and outlet must be ensured.
