2.1.1 Receiving Inspection
Inspect the packaging and equipment closely when
received. Any indication of careless handling by the carrier
should be noted on the delivery receipt, especially if the
equipment will not be immediately uncrated. Obtain the
delivery person’s signed agreement to any noted damages
for any future insurance claims. Ensure that the model
number and power match the order and intended use for
the drive.
IMPORTANT!
LOST OR DAMAGED GOODS
INSPECT THIS SHIPMENT IMMEDIATELY UPON ARRIVAL
If goods are received short or in damaged condition, insist
on a notation of the loss or damage across the face of the
freight bill. Otherwise no claim can be enforced against
the transportation company. If concealed loss or damage is
discovered, notify your carrier at once and request an
inspection. This is absolutely necessary. Unless you do this
the carrier will not entertain any claim for loss or damage.
The agent will make an inspection and can grant a
concealed damage notation. If you give the transportation
company a clear receipt for equipment that has been
damaged or lost in transit, you do so at your own risk and
expense.
Danfoss is willing to assist you to collect claims for loss or
damage, but willingness on our part does not make us
responsible for collection of claims or replacement of
material. The actual filing and processing of the claim is
your responsibility.

Ensure that the model number and power match the order
and intended use for the drive.
2.1.2 Pre-installation Check
1.
Compare panel model number to what was
ordered.
2.
Ensure each of the following are rated for the
same voltage:
•
Drive
•
Panel
•
Power line
•
Motor
3.
Ensure that the panel output rating is equal to or
greater than motor total full load current for full
motor performance.
•
Motor power size and panel must match
for proper overload protection.
•
If panel rating is less than motor; full
motor output cannot be achieved.
4.
Check motor wiring:
•
Any disconnect between drive and
motor should be interlocked to drive
safety interlock circuit to avoid
unwanted drive trips.
•
Do not connect power factor correction
capacitors between the drive and motor.
•
Two speed motors must be wired
permanently for full speed.
•
Y-start,
Δ
-run motors must be wired
permanently for run.
2.1.3 Installation Site Check
•
Because the panel relies on the ambient air for
cooling, it is important to observe the limitations
on ambient air temperature. Derating concerns
start above 104°F (40°C) and 3300 feet (1000m)
elevation above sea level.
•
It is important with multiple panels to check wall
strength. Make sure that the proper mounting
screws or bolts are used.
•
Ensure that the wall or floor area for installation
will support the weight of the unit.
•
If construction work continues after the
equipment is mounted, it is important to keep
the interior free from concrete dust and similar
