2.3 Foreseeable misuse
¯ Do not operate the motors
– ... in explosion−protected areas
– ... in aggressive environments (acid, gas, vapour, dust, oil)
– ... in water
– ... in radiation environments
Note!
Increased surface and corrosion protection can be achieved by using
adapted coating systems.
2.4 Residual hazards
Protection of persons
¯ The motor surfaces can become very hot. Danger of burns when touching!
– Provide protection against accidental contact, if necessary.
¯ Danger of unintentional starting or electrical shocks
– Connections must only be made when the equipment is deenergised and the
motor is at standstill.
– Installed brakes are no fail−safe brakes.
Motor protection
¯ Installed thermal detectors are no full protection for the machine.
– Installed overload protection does not prevent an overload under any
conditions.
¯ Installed brakes are no fail−safe brakes.
– The torque may be reduced by disruptive factors that cannot be influenced such
as contamination by oil.
¯ Fuses are no motor protection.
– Use current−dependent motor protection switches at average operating
frequency.
– Use installed thermal detectors at high operating frequency.
¯ Too high torques cause a fraction of the motor shaft.
– The maximum torques according to catalogue must not be exceeded.
¯ Lateral forces from the motor shaft may occur.
– Align shafts of motor and driving machine exactly to each other.
¯ If deviations from normal operation occur, e.g. increased temperature, noise,
vibration, determine the cause and, if necessary, contact the manufacturer. If in
doubt, switch off the motor.
