4. Installation
4.1 Mechanical Installation
♦ Only install the converter in the vertical position.
♦ Allow a distance of 50 mm above and below the drive regulator for air-circulation
♦ Ensure the unobstructed circulation of exhaust air
♦ When the cooling air is contaminated by dust, lint, aggressive gases and greases, which
could impair the functioning of the drive regulator, sufficient countermeasures must be
taken, e.g. separate air ducts, installation of filters, regular cleaning etc.
♦ Do not exceed the permitted operating temperature range.
♦ If the drive regulator is exposed to vibrations or tremors, vibration damping is required.
4.2 Electrical Installation
♦ The regulator contains components sensitive to electrostatics. Before installation and
service work in the terminal clamp area, the staff must free itself of electrostatic electricity.
The discharging can be achieved by touching a grounded metal surface beforehand.
♦ Due to the discharge currents of the drive regulator (>3,5 mA) via the protective
conductor (PE), the input diameter of the protective conductor must be at least 10 mm²
Cu according to DIN VDE 0160, or a second protective conductor must be laid, electrically
parallel. With greater connection powers, the minimum diameter of the protective
conductor must correspond to the diameter of the external conductors.
(see DIN 57100 Part 540)
♦ The regulations for the minimum diameter of PE conductors must be observed.
The diameter of the PE conductors must be at least as large as the diameter of the
conductor connections.
♦ The drive regulator can only be safely switched using a mains contactor in the input.
♦ To protect the power supply cables, the recommended cable protection fuse is required
♦ We recommended conducting the temperature monitoring of the motor using a thermal
protection switch and the monitor switching, which is integrated in the converter.
♦ Control wiring and power cables must always be spatially separated from each other.
♦ Set-value inputs, analogue control inputs and measurement outputs must be shielded.
♦ Conductor diameters for power supply and motor wiring must be at least 1,5 mm²!
♦ Observe the current local safety regulations.
