for torque tightening values.
8.3 Active Section (Bottom) Instructions
8.3.1 Input Terminal Mounting Plate
CAUTION
Two Person Lift
The input terminal mounting plate supports various
customer-ordered options. The input terminal mounting
plate with options attached can exceed 35 kg (60 lbs).
Assistance is required for removal. Failure to provide
assistance when during removal could result in personal
injury.
Note that the input terminal mounting plate provides
mounting for various options. The fused disconnect option
is shown.
1.
Disconnect the line power input wiring from
terminals L1, L2, L3 and the ground connector.
2.
Remove the 3 cross bus bars between the input
terminals and the input inductor. (These are
located above the optional RFI filter if the RFI
filter is present.) Remove three nuts (0.67 in [17
mm]) (not shown), three (T-40) screws, and (0.51
in [13 mm]) nuts from the passive side of the
unit.
3.
Remove input terminal mounting plate by
removing eight (0.39 in [10 mm]) retaining nuts
from plate.
