" 24 V Back-Up Option (Option D)
External 24 V DC Supply
An external 24 V DC supply can be installed for low-voltage s up ply to the contr ol card and any option card
installed. This enables full operation of the LCP (including the parameter setting ) without connection to line.
External 24 V DC supply specification:
Input voltage range ...................................................................... 24 V DC +15 % (max. 37 V in 10 s)
Max. input current .................................................................................................................. 2.2 A
Max cable length .......................................................................................................... 246 ft (75m)
Input capacitance load ......................................................................................................... < 10uF
Power-up delay .................................................................................................................... < 0.6 s
The inputs are protected.
Terminal numbers:
Termina l 35: - external 24 V DC supply.
Term inal 36: + external 24 V DC supply.
Follow these steps:
1. Remove the LCP or Blind Cover
2. Remove the Terminal Cover
3. Remove the Cable Decoupling Plate and
the plastic cover underneath
4. Insert the 24 V DC Back-up External S upply
Option in the Opt ion Slot
5. Mount the Cable Decoupling Plate
6. Attach the Ter mi nal Cover and the LCP
or Blind Cover.

Brake Resistors
Brake resistors are used in a ppl ications where high dynamics are nee ded or a high inert ia load must be
stopped. The brake resistor is used to remove the energy from the DC link in the adjustable frequency drive.
" Remote-mounting Kits for LCP
The remote k it option makes it possible to move the
display from the adjustable frequency drive e.g.
to the front panel of an integrated cabinet.
