Installation notes
Installation
8.1.9
Cable lengths for individual drives
•
The cable lengths depend on the PWM frequency. The permitted motor cable lengths
are listed in the "Project Planning" section of the MOVITRAC
®
B system manual.
8.1.10 Unit output
•
Only connect an
ohmic/inductive load (motor)
, do not connect a capacitive load!
8.1.11 Braking resistor connection
•
Cut the lines to the required length.
•
Use
2 tightly twisted leads or a 2-core shielded power cable
. Cross-section
according to the rated output current of the inverter.
•
Protect the braking resistor with a
bimetallic relay
with trip class 10 or 10A (wiring
diagram). Set the
trip current
according to the
technical data of the braking
resistor
.
•
For
BW..-T
braking resistors, you can connect the
integrated thermostat using a
2-core, shielded cable
as an alternative to a bimetallic relay.
•
Flat-type braking resistors
have internal thermal overload protection (fuse which
cannot be replaced). Install the
flat-type braking resistors
together with the
appropriate
touch guard
.
