*) The bending radius of the connection cables must also be taken into account
Example:
Motor cable 4 x 70 mm

-> D = 42 mm (for D3-DA 310/x-A3xx)
(D = outside Ø of the motor cable)
Bending radius (acc. to EN 60332-1-2):
For xed laying 5 x D = approx. 210 mm
to 7 x D = approx. 292 mm
depending on the cable type
Figure 3.3 Mounting clearances, KeDrive D3-DA BG4
NOTE:
It is imperative the min. mounting clearances above and below are met for
thermal reasons. Depending on the connection cables used (mains cable/
motor cable), the mounting clearances may increase signicantly due to the
bending radii necessary.
3.3 Cooling of the devices with air cooling
Cooling air must be able to ow through the device (interior and heat sink) without
restriction. If a thermal cut-out occurs, the cooling conditions must be improved.
Note:
Due to the compact design, the
KeDrive D3 DA axis controllers
are equipped with internal fans for
optimal heat dissipation. The speed
of these fans is set as a function of
the heat sink temperature. The fan
noise may therefore vary depending
on the load.
