10 FlexiMova
®
mm version with electrolytic capacitors
The FlexiMova® mm converter is also supplied in the version with built-in
electrolytic capacitors: This configuration arises from the need to connect to
particularly unstable lines with high inductiveness (for example generators) or
with particular dynamics where the DC voltage is subjected to abrupt
fluctuations.
In all these critical conditions the capacitors compensate for any voltage dips
and abrupt fluctuations of the DC link.
The capacitors are available in sizes A, B and C in a box affixed externally and
connected with the cable glands provided on the product (+ and – DC
connection)
The box containing the capacitors is available in two models:
•
standard single external box for all the models of sizes A and (dimensions
130 x 210 x 71.5 mm).
•
standard single external box for all the C sizes (dimensions 238 x 277 x 83.5
mm).
Both external boxes are affixed to the product by means of mechanical fixings
(see chap.7) .
For both types of external boxes there also exists a version for direct
mounting on the motor. For bigger sizes (sizes D and E) to install the
capacitors the product must be equipped with an electrolytic capacitor
board.
The FlexiMova
®
mm converter version with electrolytic capacitors for sizes
A, B, C must be OFF when being installed.
ATTENTION
Be sure to connect FlexiMova
®
mm converter version with electrolytic
capacitors with correct + and - polarity: a wrong connection will damage
the converter.
ATTENTION
The FlexiMova
®
mm converter version with electrolytic capacitors for sizes
D, E must be requested at the time the order is placed.
Even after power off dangerous voltage can remain on the DC-link
capacitors. To prevent personal injury, ensure that the voltage is cut off
before working on the converter and wait 10 min for the capacitors to
discharge to a safe level. Use a multimeter to test for residual DV voltage.
WARNING
Only genuine accessories and spare parts must be used.
Always replace the safety and protection devices immediately on
completion of the procedure.
ATTENTION
It is strictly prohibited to work on the product in the presence of voltage.
