SECURING AND WIRING THE DRIVE
The mounting holes in
the
corners of the drive provide the means of mounting the drive
to the system chassis or bulkhead. It is desirable to mount the drive close to the motor
and to make the motor phase wiring as short as possible. This will help to minimize
noise generated from this source. Although the drive is impervious to dirt and grease,
the connector must be protected from contamination.
A major factor in choosing the mounting location is heat sinking. An aluminum chassis
will extract heat from the drive while a steel one will not. Dirty or painted surfaces are
poor heat conductors. Clean the mating surfaces between drive and chassis before
assembly. Use of a commercial transistor heat sink compound enhances the dissipation
of heat from the CN0165 drive.
The protection provided by the internal temperature sensor of the CN0165 is not
designed as a substitute for adequate heat sinking. Repeatedly tripping the Fault Output
by allowing the drive to overheat causes thermal stress that will eventually lead to
permanent damage.
If this occurs it will be necessary to provide additional heat sinking. As a practical
guide, additional heat sinking will be necessary for the CN0165 if it is operated at three
amps or more. A fan to force air circulation through the heat sink may also be required.
The optional HSK heat sink kit for Centent drives consists of heat sink, side rails and
screws to secure the drive and side rails. The side rails are reversible, allowing the two
mounting configurations shown in

No additional connectors are required when wiring to the Terminal Connector of the
CN0165. Either stranded or solid conductor wire may be used. A wire size of 16-22
gauge is recommended. The insulation should be stripped back 0.25 inches (7 mm) for
insertion into the terminal block. Care must be taken when tightening the screws in the
terminal block. Use a torque limiting driver if possible, to avoid damage to the
terminals.
CAUTION: DO NOT OVER-TORQUE THE TERMINAL CONNECTOR
SCREWS. MAXIMUM TORQUE ON THE TERMINALS IS 4.5 LB. - IN.
