•
An undisturbed operation of the power feedback unit is only probable, if the following
instructions are observed. If these instructions are not observed, tripping of the unit
and damages may occur.
•
Pay attention to the correct values of mains and DC-bus voltage.
•
Separate power and control wires (> 15cm)
•
Use shielded or twisted control wires. Connect both ends of the shield to ground!
•
When using the digital input devices, only use suitable switching devices, whose
contacts are able to switch the connected voltages.
•
Connect the housings of drive, controller and power feedback unit to ground
carefully. Connect shields of power cables to ground at both ends with as big
surface as possible (remove lacquer)!
•
Connect the cabinet or the plant by a star-shaped network to ground (ground
loops have to be avoided!)
•
The power feedback unit has been designed for a fixed connection to mains only. Es-
pecially when using RFI-filter leakage current values> 3,5mA may occur. The cross
section of the earthing conductor must be at least 10mm² copper, or a second conduc-
tor has to be connected in parallel (star shaped grounding network).
•
If components are used, which have no electrical separated inputs / outputs it is neces-
sary to equalize the potentials (e.g. by an equalizing wire). If this is not observed, the-
se components may be damaged by equalizing currents.
•
When carrying out an insulations test in accordance with VDE0100/part 620 the de-
vice has to be disconnected to avoid damage to the power semiconductors. This proce-
dure corresponds with the standard, as each device performs a high voltage test in ac-
cordance with VDE 0160 (EN 50178) in the course of final testing after manufactur-
ing.
