Input Terminal Mounting Plate Assy Option - Danfoss VLT Series Service Manual

7.8 Input Terminal Mounting Plate Assy Option

The drive has component options that mount to the input
mounting plate. This results in differing unit configurations. These
options include input terminal blocks, input disconnect, RFI
filter, input fuses, and an additional cooling fan. These options
may need to be removed from the mounting plate assembly
to reduce the weight of the assembly for ease of removal.
1. Disconnect input power wiring from terminals L1,
L2, L3, and ground connector.
2. Remove upper most bus bar retaining nut (17
mm) from each of three terminals.
3. If a disconnect (not shown) is mounted, remove
disconnect from terminal plate assembly to
reduce weight of terminal plate as follows.
a. Loosen connection nut (17 mm) between fuse
and disconnect.
b. Remove 4 mounting screws (T40) from
disconnect.

35 pounds (16 kg). Slide disconnect down to
clear fuses and remove.
4. If cooling fan is mounted, disconnect fan cable.
5. If RFI filter is mounted, disconnect RFI cable.
6. Note that weight of terminal plate without
disconnect can be up to 44 pounds (20 kg). To
remove terminal plate, remove 8 retaining nuts (10
mm) from terminal plate and lift entire assembly
from mounting studs.
Reinstall in reverse order of this procedure. Tighten 10 mm
mounting nuts to 35 in-lbs (4.0 Nm), 17 mm connection nuts
to 170 in-lbs (19.2 Nm) and T40 mounting screws to 85 in-lbs
(9.6 Nm).
