3. INSTALLATION AND OPERATION
Install device vertically with terminals at the bottom.
Ensure a free space of 100 mm at the top and bottom and 50 mm at either side.
Connect the fixing screw of the reference potentiometer to PE.
The inverters must not be connected to mains with an earth-Ieakage current
breaker, without additional measures (e.g. zeroing) (see VDE0160/5.88). In case
of an earth fault, a DC component in the fault current can prevent the release of
the earth leakage current breaker.
Maintain a time of 3 minutes between mains disconnection and reconnection.
Internal components to limit the switch-on current must cool in order to prevent a
failure of internal or external fuses.
Plug terminals for control and power connections may only be connected or
disconnected when the device is without voltage.
Model 8106_A may only be operated with the specified mains choke.
The motor connected may not be switched via a contactor when the drive is
enabled, except in emergency situations.
Replace defective fuses only with the specified type when the device is switched
off.
Warning: The device carries potential up to 30s after mains disconnection.
The cooling air temperature must not exceed 45°C. If the cooling air contains
pollutions (dust, flakes, aggressive gases) which may impair the inverter function,
ensure sufficient protective measures, such as separate air ducts, installation of
filters, periodical cleaning. In ca se of condensation, disconnect the device from
the mains and wait until the visibile humidity has evaporated.
The types 8101_A to 8105_A are designed for a continuous thermal current limit
of 1.2'IN and type 8106_A for 1.0'IN. In case of load changes make sure that
these values are not exceeded, otherwise the temperature trip may become
effective. The effective continuous current is permissible, if leff s 1.2'IN (for
8106_A: leff s 1.0'IN) and the connected motor is not overheated.
Warning: With corresponding settings, this device generates an output frequency
up to 480 Hz. If connected to an unsuitable motor, dangerous overspeed
may result.
