2.3.2 External brake resistor SK BRE4-...
The external brake resistor (available for SK 1x0E, Size 2) is
intended for energy feedback, e.g. in pulse drives or lifting
gear. Here, it may be necessary to plan for the exact brake
resistor required.
For installation, an M20 screw connection with an adapter for
M25 is supplied. The connecting wires for the brake resistor
are fed through this into the connection unit. Because of the
cable gland the brake resistor and an optional SK TU4-
technology unit must not be mounted on the same side of the
frequency inverter.
The brake resistor is attached to the side of the connection unit using 4 suitable M4 x 10 screws. Installation
of an SK
BRE4… is not possible in combination with the wall-mounting kit SK TIE4-WMK(-L).
