3.3 Voltage Selection Panel
The voltage selection panel is a multi-tap enclosed transformer
mounted in the enclosure (Figure 9). Seven front accessible volt-
ages taps from 208 - 600 Vac satisfy any required application
voltage. A quick change capability from one voltage to another is
provided by a small disconnect plug.
3.4 Transformer Panel
The transformer panel provides indication of source availability
and switch position indication.

3.5 Options
Switch options, which are not part of the logic scheme, are avail-
able to meet a variety of other application requirements. Options
are numbered with an associated description. More detailed selec-
tions that must be made within a specific option are lettered. For
available options associated with the logic scheme, refer to the
specific logic document associated with the type of logic selected.
16. Power Switch with Integral Overcurrent Protection
Use of this option can, in many cases, eliminate the need for sep-
arate upstream overcurrent/short circuit protection, thus enabling
code requirements to be met with a device that takes up less
space and requires less wiring.

3.6 Enclosure
The rugged steel switch enclosure is supplied with three door
hinges, regardless of enclosure size, to ensure proper support of
the door and door-mounted devices (Figure 11). The hinges have
removable hinge pins to facilitate door removal. Certain proce-
dures, such as switch mounting, are simplified with the door
removed. The doors are supplied as standard with a key lockable
handle.
The door is used to mount a variety of lights, switches and push-
buttons, depending upon the options required for a particular
switch. All switch doors are supplied with a heavy duty plastic
accessory panel in place, whether or not external devices are
required. When lights, pushbuttons or switches are required, they
are normally mounted in the plastic door-mounted panel.
The rear of the enclosure is supplied with elongated holes in the
top and bottom mounting flanges to facilitate mounting. The verti-
cal design is also supplied with two positioning bolts and various
pre-tapped inserts to ensure proper positioning of the power
panel, anytime the power panel must be repositioned to accom-
modate a different cable entry position. Cable entry holes are the
responsibility of the customer.
