TOSHIBA - 8
TX Series 48 - 1250A
Chapter 2 - Installation
2.1 Receiving and Unpacking
Upon receipt of the unit:
• Carefully unpack the unit and inspect it for any shipping damage.
Report any damage immediately and file a claim with the freight
carrier within 15 days of receipt.
• Verify that the model number on your unit matches your purchase
order.
• Confirm that the ratings label on the unit matches or is greater than
the motor’s HP and current rating.
2.2 Initial Unit Inspection
• Make a complete visual check of the unit for damage which may have
occurred during shipping and handling. Do not attempt to continue
installation or start up the unit if it is damaged.
• Check for loose mechanical assemblies or broken wires which may
have occurred during transportation or handling. Loose electrical
connections will increase resistance and cause the unit to function
improperly.
• Prior to beginning the installation, verify that the motor and TX unit
are rated for the proper amperage and voltage.
2.3 Location
The proper location of the unit is an important factor in achieving the
unit’s specified performance and normal operation lifetime. The unit
should always be installed in an area where the following conditions
exist:
• Ambient Operating Temperature: 0° C to 50° C (32° F to 122° F)
(Optional space heaters can be provided for operation in ambient
temperature to -20° C.)
• Protected from rain and moisture.
• Humidity: 5% to 95% non-condensing.
• Free from metallic particles, conductive dust and corrosive gas.
• Free from excess vibration (below 0.5G)
• Open panel units must be mounted in the appropriate type of
enclosure. Enclosure size and type must be suitable to dissipate
heat generated by the soft starter. Contact factory for assistance in
sizing the enclosure.
Do not service equipment with voltage applied!
The unit can be the source of fatal electrical
shocks! To avoid shock hazard, disconnect
main power and control power before working
on the unit. Warning labels must be attached
to terminals, enclosure and control panel to
meet local codes.
2.4 Mounting and Cleaning
When drilling or punching holes in the enclosure, cover the electrical
assembly to prevent metal filings from becoming lodged in areas which
can cause clearance reduction or actually short out electronics. After
work is completed, thoroughly clean the area and reinspect the unit for
foreign material. Make sure there is sufficient clearance (six inches)
all around the unit for cooling, wiring and maintenance purposes. To
maximize effective air flow and cooling, the unit must be installed with
its heat sink ribs oriented vertically and running parallel to the mounting
surface.
