3.2.3 connectIng For 208 Vac InPut
After the panel is removed, locate the 208 Vac lead (Fig. 3.3B)
and cut the tie-wrap to remove the insulation sleeving (on
early models this lead may have been wrapped with black
electrical tape). Open the insulating cover around the power
switch (Fig. 3.3C.) to expose the terminals and disconnect
the 230 Vac lead from the top of the switch as shown in Fig.
3.3A. Insulate the 230 Vac lead that was removed from the
power switch with sleeving or approved electrical tape
and re-position to a safe area beside the transformer (see
Fig. 3.3B), leaving a minimum of one inch clearance from
other components and the side panel.
3.2.4 connectIng For 230 Vac InPut
After the panel is removed, locate the 230 Vac lead (Fig. 3.3B)
and cut the tie-wrap to remove the insulation sleeving (on
early models this lead may have been wrapped with black
electrical tape). Open the insulating cover around the power
switch (Fig. 3.3C.) to expose the terminals and disconnect
the 208 Vac lead from the top of the switch as shown in Fig.
3.3A. Insulate the 208 Vac lead that was removed from the
power switch with sleeving or approved electrical tape
and re-position to a safe area beside the transformer (see
Fig. 3.3B), leaving a minimum of one inch clearance from
other components and the side panel.
Connect the proper voltage (208 Vac or 230 Vac) tap to the
power switch and tighten securely. Check all other leads
connected to the power switch for tightness and clearance
from internal components before securing the insulating
cover around the power switch. Replace the side panel.
When changing the input voltage connections, the unused
lead must be insulated and positioned to prevent contact
with any other internal components of the machine or the
machine side panel. The clearance between the unused
lead and other components must be at least one inch (see
Fig. 3.3B for illustration of the proper position). FAILURE TO
INSULATE AND POSITION THIS LEAD PROPERLY WILL CAUSE
A SERIOUS SHOCK HAZARD.
