WARNING
Remove all sources of power before cleaning the unit.
In dirty or contaminated atmospheres, the unit should be cleaned on a
regular basis to ensure proper cooling. Do not use any chemicals to
clean the unit. To remove surface dust use clean, dry compressed air
only, 80 to 100 psi. A three-inch, high quality, dry paintbrush is helpful to
loosen up the dust prior to using compressed air on the unit. Do not use
wire brushes or other conductive cleaning materials.
2.6 Power Terminations
All line and load power terminations are to be made to tin plated copper
Bus Tabs located on each unit. Bus tabs are pre-drilled to accept
industry standard bolts. Some sizes come with saddle clamp terminals,
however lugs are the responsibility of the user. Toshiba recommends
using crimp-on lugs, although mechanical lugs are suitable as well. The
following diagrams show sizes of the bus tab holes and critical spacing
between them for determining the size of lug that can be used.
NOTE: All wiring must be sized according to local code standards.
