4. Installation
4.1 Mechanical Installation
♦
The drive regulator may be mounted only vertically.
♦
Allow a distance of 50 mm above and below the drive regulator for air-circulation
♦
Area to be left clear min. 20mm sideways
♦
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.
(see Cap. 3.4)
♦
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 (GRD) metal surface beforehand.
♦
To protect the power supply cables, the recommended cable protection fuse is required
♦
Control wiring and power cables must always be spatially separated from each other.
♦
Set-value inputs must be shielded.
♦
Conductor diameters for power supply and motor wiring must be at least 1,5 mm²!
♦
Observe the current local safety regulations.
♦
Use 60/75°C copper wire only
♦
Tightening torque for field wiring terminals
♦
Use in a pollution degree 2 environment
♦
“Use Class 1 wire only” or equivalent
Motor over temperature sensing according UL 508C is not provided by the drive or
equivalent.
