Ambient conditions
• The following ambient conditions must be ensured
on site
Altitud: max. 1,000 m a.s.l.
Ambient temperature: -5°C ... 40 °C
Max. rel. humidity: 85% at 20°C
(no moisture condensation)
• Install the machine so that ventilation is not obstruct ,
ed, i.e. sufficient heat dissipation by convection and
radiation must be ensured.
• The torque and power values indicated in the techni cal
data apply to the above ambient temperatures and
altitudes. In the case of a deviating altitude and/or
temperature, the reduction factors k shown in the dia-
gram "Ambient conditions" must be used.

4.2. Electrical connection
4.2.1. General
• Before starting any work on the machines, ensure that the lift machine or system is properly isolated.
Before making any electrical connections check that
• the connecting cables are suitable for their specific application and for the relevant voltages and currents.
• sufficiently dimensioned connecting cables, torsion, strain and shear relief, as well as anti-kink protection are
provided
• the protective conductor is connected to the earthing terminal
• there are no foreign bodies, dirt or moisture in the terminal boxes
• cable entries not in use and the terminal box itself are tightly sealed to prevent the ingress of dust or
splash ing water.
Caution
The insulation system of the motors is designed such that they can be connected to a
inverter with a maximum DC link voltage U
link max
up to max. 700 V DC.
U
link max
is the maximum value of the DC link voltage which is only transient and approxi mately
equivalent to the inception voltage of the braking chopper or of the energy recovery unit.
The maximum permissible rate of voltage rise (dU/dt) at the motor terminals is 4kV/µs. The
overvoltage at the motor terminals must not exceed 1.56 kV. It may be necessary to use
motor current filters or reactors to achieve these values.
Warning
The electrical connection may only be made by a qualified electrician.
