General Start-Up

General Start-Up Procedure
The following is a recommended start-up
procedure:
1. The HPV 900 Series 2 is thoroughly tested
at the factory. Verify the drive has been
installed without shipping and installation
damage.
2. Review the HPV 900 Series 2 technical
manual, shipped with the drive.
3. Verify the proper drive model numbers and
voltage ratings as specified on the
purchase order.
4. Verify the drive has been installed in
accordance with the guidelines detailed
below:
Location of the HPV 900 Series 2 is important
for proper operation of the drive and normal life
expectancy. The installation should comply
with the following:
DO NOT mount in direct sunlight, rain or
extreme (condensing) humidity.
DO NOT mount where corrosive gases or
liquids are present.
AVOID exposure to vibration, airborne dust
or metallic particles.
DO NOT allow the ambient temperature
around the control to exceed the ambient
temperature listed in the specification.
Mount control vertically using mounting
holes provided by Magnetek.
Allow at least 7cm (2.5 in) clearance above
and at least 7 to 13 cm (2.5 to 5 in)
clearance below the unit.
Allow at least 3 cm (1 in) clearance to
either side of the drive.
Separate grounded metal conduit is
required for input, output and control
wiring.
The unit should be installed in an open
ventilated area where free air can be circulated
around the control. The installation should
comply with the following:
When necessary, the cooling should be
provided by using filtered air.
If the cooling air coming inside the control
cabinet contains airborne dust, filter the
incoming air as required and clean the
cooling surface of the HPV 900 Series 2
regularly using compressed air and a
brush. An unclean heatsink operates at an
efficiency less than that of cooling design
specifications. Therefore, drive may fault
on thermal protection if heatsink is not
cleaned periodically.
5. Inspect the security of the supply line
power, ground connections, and all control
circuit connections. Ensure that the main
circuit input/output precautions are
observed. Also, ensure that the control
circuit precautions are observed.
Observe the following precautions:
Use 600V vinyl sheathed wire or
equivalent. Wire size should be
determined considering voltage drop of
leads.
Never connect main AC power to the
output terminals: U, V, and W.
Never allow wire leads to contact metal
surfaces. Short circuit may result.
SIZE OF WIRE MUST BE SUITABLE FOR
CLASS I CIRCUITS.
Motor lead length should not exceed 45m
(150 ft) and motor wiring should be run in a
separate conduit from the power wiring. If
lead length must exceed this distance,
contact Magnetek for proper installation
procedures.
Use UL/CSA certified connectors sized for
the selected wire gauge. Install
connectors using the specified crimping
tools specified by the connector
manufacturer.
Use twisted shielded or twisted-pair
shielded wire for control and signal circuit
leads. The shield sheath MUST be
connected at the HPV 900 Series 2 ONLY.
The other end should be dressed neatly
and left unconnected (floating).
Control wire size should be determined
considering the voltage drops of the leads.
Control wire lead length should not exceed
45m (150 ft). Signal leads and feedback
leads should be run in separate conduits
from power and motor wiring.
6. Verify that the input voltage matches the
dri
ve’s rating.
7. Verify that the motor is wired for the
application voltage and amperage.
8. Tighten all of the three-phase power and
ground connections. Check that all control
and signal terminations are also tight. As
they sometimes come loose during the
shipment process.
IMPORTANT
The drive has a common ground bus terminal
connection. All grounds need to land at this
common point including building, motor,
transformer, and filter grounds. This will limit the
impedance between the grounds and noise will
be channeled back to building ground.
