HAZARDOUS LOCATION SWITCHES — Switches for hazardous
locations meet Division 2; Class I Groups A, B, C, & D; Class II,
Groups F & G; and, Class III requirements. For additional
information refer to Publication GI-2.8 — A Summary of
National Electrical Code Requirements for Hazardous Locations.

NOTE: To guard against the load remaining energized when the
switch is in an open condition, the minimum load release current
must be greater than the maximum leakage current of the
proximity switch.
GROUNDING — The Bulletin 802PR does not require a ground
connection. The load side of the110/120V AC source can be
grounded as indicated in the connection diagram.
SHORT CIRCUIT PROTECTION — A fuse is recommended in the
circuit to provide short circuit protection for the switch. Use a fast
acting Type KAW10 or KAX10 fuse.
SERIES CONNECTED SWITCHES —
Normally Open Fixed Output — Do not connect two or more
of the switches in series. Erratic operation may result.
Programmable Normally Open/Normally Closed Output
— Two switches can be connected in series with a load. For
proper operation, the operating load voltage must be less than or
equal to the minimum supply voltage less the sum of the onstate voltage drops across the series connected proximity
switches. The load will be energized when the OUTPUT LEDs of
both proximity switches are ON.
CONNEC TION DIAGRAM
WIRING — Connect the proximity switch and load as shown in
Figure 5 using AWG #18 through #14 wire (1.0/1.5mm
of the switch will be ON when the load is energized.

N.O./N.C. proximity switch is factory preset in either the normally
open or normally closed output mode.
To change the switch output mode use the following instructions.
1. Remove the lower legend plate on the front of the switch.
2. A line on the recessed rocker indicates the output mode of
the switch.
3. To change the output, depress the recessed rocker of the
switch with a pointed tool.
Note: Do not use a tool whose point could break and jam the
switch.
4. Replace the lower legend plate.
To return the output mode to its original setting, simply reverse
the above procedure. The OUTPUT LED will be ON when the
switch output is conducting.
HARD WIRED CONTACTS — When hard wired contacts are
connected in parallel with the Bulletin 802PR, a surge suppressor
MUST BE connected in parallel with the load. Surge suppression is
not required when hard wired contacts are connected in series
with the load. For recommended surge suppressors for various
devices, refer to publication 802PR-2.1 product data.
NOTE: Hard wired contacts that are operating in series or parallel
with the Bulletin 802PR Type LA or Type XA will cause a delay of
approximately 200 ms. This power-up delay will reduce the
maximum number of operations per minute and may result in a
momentary de-energization of the load.
CONDUIT CO UPLED SWITCHES — Threaded conduit opening
bases are suitable for use with flexible conduit. Conduit coupler
bases are suitable for use with both flexible conduit and rigid
conduit. Both bases connect to 1/2 in.-14 NPT threaded conduit.
Switches with a “S6” suffix in their catalog number are suitable
for connection to ISO 20-1.5 threaded conduit.
PREWIRED CABLE SWITCHES — These switches include a
prewired cable for connection directly into a junction box. The
cable is a two conductor, oil resistant thermoplastic (STO).
PREWIRED RECEPTACLE SWITCHES — These switches include
a prewired receptacle suitable for use with the connector-cable
assemblies listed in the table below. Figure 6 indicates which two
pins of the receptacle are wired internally to terminals 1 and 2.
The third pin is not used.
