enclosures. IP 65
ASSEMBLY INSTRUCTIONS
1. Select the desired schematic circuit function from the chart below and
note in your cam column the type of contacts, N.O. or N.C., the “A” and
“B” circuit locations, and any series or parallel jumper connections the may
be required.
2. Choose contact blocks that have the required schematic circuits and
assemble in any convenient sequence that fulfills the “A” and “B” circuit
location requirements.
NOTE: Single circuit contact blocks, if used, must be last in the stack and
positioned so that the plunger motion is transmitted through.
3. Make the indicated series or parallel jumper connections.
(10250T/91000TA70,TA71).
4. If this operator was received without an operating cap, assemble the
separately purchased cap, assemble the separately purchased cap and secure
with the screws provided.
NOTES: Single, double and 2NO-2NC contact blocks are available. Six contacts
can be stacked in each of the two circuit locations making a maximum of
twelve circuits possible.
For additional selector switch explanation ask for manual NU-118.
The two sections of the operating cam of this selector switch work
independently, so it is important that the contact blocks be oriented with
their plungers in the correct “A” and “B” circuit locations. The sketch below
identifies these positions with respect to the locatin nib or marked top.

VERTICAL MOUNTING
. For
HORIZONTAL MOUNTING
loosen the set screw and assemble so that the locating nib is at the left.
ILLUMINATED GASKET INSTRUCTIONS
This operator was shipped with
the gasket oriented for
VERTICAL MOUNTING
using lever lens and the
new type knob lens.
For
HORIZONTAL MOUNTING
(or VERTICAL MOUNTING using the old
type knob) carefully peel the lens gasket, rotate it 90°, and press onto the
operator. (Lens screws will now thread into alternate holes).
LAMB REMOVAL TOOL For Trans. Type Cat. No. 10250TA74 for Full Voltage
Type E30KV1.
1. Drill mounting hole for vertical or horizontal mounting per one of the figures
above.
2. ensure sealing gasket is in the place on the operator. Align location nib
of the operator with notch in the panel and insert operator through mount-
ing hole.
3. Place legend plate and mounting nut over operator. Tighten mounting
nut. If applicable assemble buttons to operator. Tighten securely (5 ft-lbs)
(6.8 Nm).
4. Torque terminals to 12 in/lbs (1.4 Nm).
For ease of assembly, we recommend the following tools:
91000T/10250TA95 (for 10250T/91000T octagonal nut, E29 and E30 line)
E22CW (for 10250T/91000T octagonal nuts, E22, E30 and E34)
5. Torque contact block stacking screws to 5-7 in/lbs (0.57- 0.79 Nm)
The selector switch operator in this package may not be complete. A knob,
lever, coin slot or knob type lens operating cap is required wich may be
merchandised and packaged separately.
