NOTICE
For personnel safety, snap-off tabs protect the power
terminals on models up to MCD5-0105B. When using
large cables, it may be necessary to break off these tabs.
NOTICE
Some units use aluminum busbars. When connecting
power terminations, clean the surface contact area
thoroughly (using an emery or stainless steel brush), and
use an appropriate jointing compound to prevent
corrosion.
Use only copper stranded or solid conductors, rated for
75
°
C (167
