Environmental Conditions And Location; Installation Guidelines - Trane AFDH Installation Instructions Manual

Installation
Environmental Conditions and
Location
Important: Location of the harmonic filter is important
if proper performance and normal
operating life is to be expected. Therefore,
unless designed for special environments,
the controller should be installed in an area
where the following conditions exist:
• Verify that NEMA 1 enclosure is installed where it can
be kept clean and dry, away from oil, coolants, or other
airborne contaminants. The enclosure must be
installed in a non-corrosive location.
• The area chosen should allow the space required for
proper air flow. Adequate clearance for air circulation
around the enclosure is a 6 inch (15.25 cm) minimum
clearance required wherever vents are located in the
cabinet.
• The area chosen should allow for service clearance in
front of the enclosure. Three feet (0.91 m) is
recommended for door swing and working space;
more space may be required by local building codes or
for service equipment, such as hoists used for drive
replacement. Because codes and equipment may vary,
determine the amount of space required for each
specific installation.
• Do not install the harmonic filter over 1000 meters
(3300 feet) above sea level without derating output
power. For every 160 meters (528 feet) over 1000
meters (3300 feet) above sea level, derate the output
current 1 percent.
• IDEALLY, THE FILTER SHOULD BE INSTALLED AS
CLOSE TO THE AFD AS POSSIBLE. RECOMMENDED
MAXIMUM CABLE DISTANCE BETWEEN THE FILTER
AND DRIVE IS 100 FEET.
• Line voltage is 480 Vac ±10%, 60 + 0.75 Hz, 3 phase
• Verify that the drive location will meet the
environmental conditions specified in
Table 31. Environmental conditions

Installation Guidelines

Lift the filter into position on existing or new concrete pad.
Care should be used to prevent damage due to dropping
or jolting when moving the filter. A fork lift truck or similar
means of lifting and transporting may be used. Sling in a
manner that will equalize the load at the pickup points. Use

a spreader bar if the angle of the sling is less than 45°
relative to horizontal. Do not jolt while lifting.
Heavy Objects!
Failure to follow instructions below or properly lift unit
could result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings) may
not be of the same length. Adjust as necessary for even
unit lift.
1. Mark hole location on floor for anchor bolts.
2. Remove filter cabinet.
3. Drill holes for anchor bolts.
4. Reset filter cabinet over holes.
5. Install field-provided anchor bolts.
Use the following steps to connect power wiring to the
filter:
1. Wire size should be based on nameplate amps and
local code requirements (NEC). Use metallic conduit/
shielded cable in accordance with local codes. If cable
runs near other circuitry wire, it is recommended to run
cable perpendicular to other wire(s). Use only copper
conductors for the input power leads
2. There are no knockouts in the cabinet. Entry/exit
openings must be made in the field. RECOMMENDED
ENTRY/EXIT OPENINGS ARE THROUGH THE TOP.
Avoid getting any enclosure shavings on the filter
components. A punch out is recommended to make
hole.
3. Install the appropriate conduit hubs in the filter
enclosure.
50.
4. Wire termination devices on the primary and
secondary of the filter must be field furnished and
installed. Ring-type compression terminal devices are
suggested.
5. Install the appropriate conduit hubs.
6. There are no knockouts in the drive cabinet. Entry/exit
openings must be made in the field. Avoid getting any
enclosure shavings on the drive components. A punch
out is recommended to make hole.
7. Install the appropriate conduit hubs in the drive
enclosure.
8. Remove the bus bars connecting the circuit breaker to
the drive.
9. Connect the power leads between the filter and the
drive components. Connections are listed in the
following table.
