The maximum specified rating of the BWS-T2 output contacts must not be
exceeded.
With inductive loads, arc suppression or switching as described below
should be utilized. For user tools that require load currents that exceed the
BWS-T2 contact rating, auxiliary power operated switches must be used
(see figure 13).
The N.O. contacts of the auxiliary power operated switches H1/H2 are used
to wire directly to the machine control itself. The N.C. contacts of H1/H2
insure that in case of a defective switch the machine will not restart.
