AQUILINE Foot Operated Switch
WIRING
===================================================================================
1.
WARNING: TO AVOID PERSONAL INJURY, DO NOT USE THIS SWITCH ON MACHINERY WITH AN
UNGUARDED POINT OF OPERATION.
READ WARNING STATEMENT
on reverse side of this page.
2. When wiring up this device make sure
POWER IS OFF AND LINES ARE DEAD.
3. MAXIMUM FUSE RATING: Amperage and voltage not to exceed nameplate rating – Quick Acting.
4. Supply cord with flexible conductors (leads) to be prepared as shown. (See Diagram “A”).
Supply cord with prepared flexible conductors. Use special purpose crimping tools to apply female quick connect and when required, ring
terminals to conductors.
NOTE:
For metal Aquiline models, the cord must include a 4-1/2 in. (114mm) long green or for CE Marked foot switches, a green / yellow
colored grounding conductor. Apply a #8 (4.4mm ø) ring type terminal. Attach to and tighten the protective earthing (grounding terminal with
lockwasher) screw 11-16 in.-lbs. (1.2 to 1.8 Nm).
NOTE:
For CE Marked foot switches, a cord guard or bend relief must be provided that extends beyond the cord clamp at least five times the
overall diameter of the flexible cord.
Use 2 conductor cord for single pole
normally open or normally closed
operation. Use 3 conductor cord for
single pole double throw operation.
Maximum flexible conductor size: #14

Base
Make sure cover is pried off
of base from this side only.
5. Remove cover from base by prying the cover with a flat blade screwdriver on the side shown in Diagram “B”.
NOTE:
For metal Aquiline models, remove hinge screws.
6. Loosen or remove cord clamp screws, insert cord and connect inner conductors (leads) of cord to appropriate switch terminals.
(See Diagram “C”).
NOTE:
For metal Aquiline models, remove plastic insulation from switch before connecting cord leads to terminals.

This interior switch only has
Solder type terminations
IMPORTANT!
Make sure that the
hinge hole in the cover is located
over this hinge tab pins prior to
snapping the cover onto the base.
7. The circuit designations shown in Diagram "C" are at assembly. For 974-S only, the left side interior switch is reverse actuated in the foot
switch housing. For example, the normally closed terminal (NC) marking molded into the switch body will provide a normally open circuit when
the interior switch is assembled in the foot switch housing.
8. Re- assemble cover to base by snapping onto hinge tabs as shown in Diagram "D".
NOTE:
For metal Aquiline models; replace plastic insulation on switch then reassemble cover with hinge screws.
9.
CLEANLINESS
must be observed during installation and in use.
on a
REGULAR BASIS,
inspect foot switch frequently to guard against wear, damage, unlawful alterations or removal of guards, or for
unusual enclosure deterioration and the like. Inspect the entire length of the connecting cord (or wiring system) from where it enters the foot
switch to the equipment it’s wired up to for wear, loose strain relief connections and the like.
DO NOT OPERATE
the foot switch if any of the
above is observed or if the nameplate or warning label has been obscured or removed.
It is
IMPERATIVE
that inspection authorities and users exercise more than ordinary care with regard to installation and maintenance and that
this information be made available to the end user, operators, maintenance personnel and to others responsible for the proper installation and
safe operation of this foot switch.

MOUNTING
================================================================================
1. Aquiline foot operated switches are furnished with a non-skid base pad and can be mounted with the base pad attached.
2. Use 2 number 4 thread-cutting (self-tapping) screws and two number 4 lock washers when mounting foot switch to full guard.
(See Diagram "E") For metal Aquiline models, remove 2 number 4 baseplate screws and use for mounting along with two number 4
lock washer. Also, place two number 6 lock washer, furnished with guard, between the bottom of the metal Aquiline baseplate inside of guard
and check for continuity between the foot switch enclosure grounding lead and guard.
