Mounting
1. Drill mounting hole for vertical or horizontal mount-
ing per the matrix below and diagram to the right.
2. Ensure sealing gasket is in place on the operator.
Align locating nib on operator with notch in panel
and insert through mounting hole. If notched hole
is not desired, remove locating nib by placing a flat
head screwdriver between nib and operator and
prying outward. Note: When using protective boots,
see special instruction publication 20437 for place-
ment of sealing gasket.
3. Place legend plate and mounting nut over operator.
Tighten mounting nut securely (5 lb-ft / 6.8 Nm).
4. If applicable, assemble lenses, mushroom buttons,
etc. to operator. Tighten selector switch set screw
to 8 – 12 lb-in (0.9 – 1.35 Nm). Note: Ensure lens is
securely tightened to provide oiltight and watertight
seal.
For ease of assembly, the following tools are recom-
mended: 10250TA95 or E22CW for tighening octagonal
nuts. 10250TA74 — lamp removal tool for transformertype
light units. E30KV1 — lamp removal tool for full voltage light
units.

Selector Switch Selection And Assembly — Refer To
Contact Block Selection Charts
1. Select intended schematic circuit function. Note in
your “cam” column the type of contact (NO or NC),
the “1” and “2” circuit locations, and any series or
parallel jumper connections that may be required.
2. Choose contact blocks that have the required
schematic circuits and assemble in any convenient
sequence that fulfills the “1” and “2” circuit location
requirements.
3. If applicable, assemble the operator cap.
Recommended, set screw tightening torque for
selector switches is 8 – 12 lb-in (0.9 – 1.35 Nm).
4. The two sections of the operating cam work indepe-
ndently. It is important that the contact blocks be
oriented with their plungers in the correct “1” and
“2” circuit locations. The drawing to the right identi-
fies these positions with respect to the locating nib
on operator or marked top.
5. Assembled operators are factory set for Vertical
Mounting. For Horizontal Mounting, loosen the set
screw and assemble with the locating nib on the left.
ote:N Circuits shown illustrate connections to obtain a selector
circuit combination and are shown with their appropriate line dia-
grams in BOLD. Field wiring of jumper connections are required
as shown.

Push-Pull Operators — Contact Block Selection
And Assembly
The illustration to the right assists in the selection of
contact blocks. Symbols 1 and 2 show locations of
contact circuits after assembly of contact blocks and
adapter to the operator. The chart below shows the
effects of the push and pull operations on either NO
or NC contacts.
Grounding Of 10250T And E34 Components General
With any electrical component there is the possibility of a
loose wire, moisture, etc. causing a short circuit between
the component and ground. If the device is adequately
grounded, the condition causes the protective fuse or circuit
breaker to open and remove the potential. If not, an electri-
cal hazard may remain unnoticed.
Grounding Nibs — 10250T
The 10250T operator is designed to make direct metallic
contact to the rear of the panel (with no intervening spacer
washers to interfere with component-to-panel ground con-
tinuity). As a further aid in establishing an electrical ground,
the operator has four metal points (“grounding nibs”)
designed to penetrate most paints or other protective coat-
ings.
Penetration of these nibs is dependent upon the torque
applied to the mounting nut. Recommended torque is 5 ft-
lbs (6.8 Nm). More or less may be necessary to penetrate
the specific type and thickness of your panel coating. Test
for continuity to ground after installation. If a short circuit
to ground does occur, the fault should be corrected and the
device replaced.
Earth Ground Terminals — E34
These devices are supplied with an integral earth/ground
terminal. A 6-32 terminal screw will accommodate ring type
terminations for bonding to international specifications.
