Manual KVBF
5 General safety information
• During assembly, commissioning, maintenance and controls, secure both the assembly area and also the
premises for any preparations against access by unauthorised persons.
• A residual risk due to faulty conduct, malfunction or effects of force majeure in the operation of the fan
cannot be completely ruled out. The planner, operator or builder of the appliance, machine or system must
take suitable safety measures pursuant to DIN EN 12100 to prevent the occurrence of a risk situation.
• Please observe the general occupational safety directives.
• Ensure access to the fan for the purpose of upkeep and maintenance.
• Assembly and electrical installation may only be done by trained personnel complying with the relevant
directives.
• The electrical connection may only be carried out by trained electricians.
Before maintenance and repair work, switch the energy supply off.
• Rule out any risk by undesired switching on of the fan or undesired contact with the rotor during any work.
• The housing of the fan may not be deformed during assembly.
• Any risk by touching the rotor during operation must be ruled out.
• To avoid disturbances and to protect the motor, the latter must be disconnected from the mains by the
integrated resistor in the event of a disturbance in operation (e.g. inadmissibly high media temperature)
pursuant to Council Directive 94/9/EC.
• Maximum testing voltage of the resistors is 2.5 V.
• The motors contain triple resistors. More than two resistor chains may not be connected in series, as this
can lead to an undened cut-out.
• When checking the direction of rotation of the rotor, wear goggles.
• Safety elements, e.g. protective grids, may not be dismantled, circumvented or put out of function. They
are to be checked for their secure positioning.
• Compliance with EMC Directive 89/336/EEC only relates to this product if it has been connected directly
to the customary electricity mains. If this product is integrated into a system or completed and operated
with other components (e.g. regulation and control appliances), the manufacturer or operator of the overall
system is responsible for compliance with EMC Directive 89/336/EEC.
• The name plate states the electrical gures approved by the registration ofce in the EC type test (declara-
tion of conformity) for the motor when optimally cooled.
• Prevent suction of foreign bodies, this can destroy the fan.
• Guarantee uninhibited and even owing into the appliance and free blowing out again.
• The fans may not be used in explosive or hazardous areas.
