MOUNTING AND INSTALLATION
This equipment should be installed, adjusted, and serviced by
qualified electrical maintenance personnel familiar with the
construction and operation of this type of equipment and the
hazards involved. It is the responsibility of the equipment
manufacturer, or person installing the controller, to take diligent
care. Read all warnings and notes before proceeding to install or
operate this control.
The Vari Speed S1000 should be mounted in an enclosure
appropriate for the application’s environment. Failure to do so
could cause equipment malfunction or serious personal injury.
When using the higher horsepower units, the optional 176B1122
heatsink is recommended to ensure the proper heat dissipation.
The 176B1122 provides 160 square inches. This figure is based
on anodized aluminum; the type of metal and its finish will affect
the thermal resistance. The area will have to increase accordingly
to ensure proper cooling.
NOTE: Recommended minimum mounting clearance on the top
and bottom perimeter of 2 inches should be maintained to
ensure proper cooling. NOTE: Fast-on (1/4” and 3/16”)
connectors are required for wiring when optional terminal board
is not used.
1. WARNING: IMPROPER INSTALLATION OF MOTOR AND
CONTROLLER MAY CAUSE EQUIPMENT FAILURE, OR SERIOUS
PERSONAL INJURY.
