Pre-Installation
AFDJ-SVU01D-EN 31
during any construction to protect from dust and
debris.
– For export-crated drives, desiccant for two-month
storage (from date of shipment) is supplied as
standard. Desiccant for longer storage times has to
be specified at time of order. Drive may be left in
export crating until desiccant expires.
• Factory-installed space heaters are recommended to
prevent condensation if storage temperature
fluctuates or if humidity exceeds 85 percent.
• Medium voltage enclosures are designed for indoor
use and are not shipped with sufficient packaging for
outdoor storage. Make sure that adequate protection is
provided for the equipment if stored outside.
Temporary electrical heating to prevent condensation
should be installed. Space heaters rated at
approximately 150 watts per cabinet are adequate for
most enclosures. To avoid fire hazard, remove any
loose packing or flammable material from the drive
prior to powering the space heaters.
Planning
Ensure that it is possible to move the equipment into place.
Check that all ceiling, door heights and turning distances
are adequate.
Neutral Resistor Assembly
(A-Frame only)
Neutral resistors ship separately and require installation in
the field only with A-Frame medium-volt drives. Resistors
are wired from the line capacitor neutral to the motor
capacitor neutral; refer to submittal wiring diagrams for
more information.
Installation of Neutral Resistor Assembly
Note: Valid only for A-Frame configuration.
On top of the converter cabinet, a sheet metal enclosure
containing power resistors is to be installed.
1. Locate the resistor assembly on top of the cabinet as
shown in
Figure 23, p. 31 . (For acoustic hood
assembly, refer to Figure 24 .)
2. Affix the assembly to the top plate using M6 thread
forming screws provided.
3. Remove the top plate of the resistor assembly to
permit access to the wiring connection points.
WARNING
Combustible Material!
Failure to remove loose packing or flammable material
could result in death or serious injury or property
damage. If storing medium voltage enclosure outdoors
with electrical heating to prevent condensation,
remove any loose packing or flammable material from
the drive prior to powering the space heaters. Loose
packing or flammable material could result in a fire
hazard.
