3.1.2 Remove/open the lower front
cover on Frame size E2 and F2
(IP20/21)
Fig. 27 Loosen the two screws and remove the lower cover
(principle drawing)
In order to access the mains, motor, DC+/DC- and brake
terminals, remove the lower cover in following order
•
Loosen the two screws B (see Fig. 27).
•
Pull down the cover a bit and lift it away.

nd F2).
3.2.1 Mains cables
Dimension the mains and motor cables according to local
regulations. The cable must be able to carry the AC drive
load current.
Recommendations for selecting mains
cables
•
To fulfil EMC purposes it is not necessary to use
screened mains cables.
•
Use heat-resistant cables, +60
°
C (140
°
F) or higher.
•
Dimension the cables and fuses in accordance with local
regulations and the nominal current of the motor. See
table
7, page
.
•
PE conductor cross-sectional area shall for phase cable
size < 16 mm2 (6 AWG) be >10 mm2 Cu (16 mm2 Al)
or a second PE conductor with same area as original PE
conductor,
for cable size above 16mm2 (6 AWG) but smaller or
equal to 35mm2 (2 AWG) the PE conductor cross-
sectional area shall be at least 16mm
2
(6 AWG). For
cables >35mm
2
(>2 AWG) the PE conductor cross-
sectional area should be at least 50% of the used phase
conductor.
When the PE conductor in the used cable type is not in
accordance with the above mentioned cross-sectional
area requirements, a separate PE conductor should be
used to establish this.
•
The litz ground connection see fig. 37, is only necessary
if the mounting plate is painted. All the AC drives have
an unpainted back side and are therefore suitable for
mounting on an unpainted mounting plate.
Connect the mains cables according to fig. 28 to 34. The
AC drive has as standard a built-in RFI mains filter that
complies with category C3 which suits the Second
Environment standard.
