1. MODULE CONNECTIONS
a. Interconnect the S1400 module and the power supply with
the power and control cable and secure the connector in place
by tightening the screws on each side of the connector.
b. Repeat step (a.) for the interface output port (if applicable).
c. The sensor connector from the terminal block simply plugs
into the back of the S1400 module.
2. TYPICAL POWER SUPPLY CONNECTIONS
a. Conduit installation:
1) Remove power before opening power supply cover.
2) Install one

2
in. NPT or two
3
/
4
in. NPT conduits,
from customer end of the Power Supply.
Note: Follow NEC guidelines for maximum number of wires in conduit.
3) Install an approved explosion-proof seal in the conduit within 18 in.
(457 mm) of Power Supply enclosure (seal unused conduit holes).
Important: Green screw above conduit hole (power supply) is to
attach equipment ground per NEC.
b. Customer Wiring: Install non-intrinsically safe wiring to
power supply through conduit installed in “step 2-a”.
1) Run wiring from the power source to the S1400 power supply.
2) Connect the 120 VAC “L1”lead to terminal 1 in power supply.
3) Connect the 120 VAC “N”lead to terminal 2 in power supply
and connect ground to terminal 4, and to equipment ground.
4) For 12 or 24 VDC, connect “DC (+)” lead to terminal 3 on
power supply. Connect “DC (–)” lead to terminal 4.
(Refer to Power Supply Wiring Diagram, supplied with your unit.)
3. NORMALLY OPEN SENSOR INPUT WIRING
Wire each normally open sensor on top of the factory supplied
jumper. Loosen the screw and slide the wire lead into the
terminal without removing the jumper (either side of jumper).
4. NORMALLY CLOSED SENSOR INPUT WIRING
Remove the factory-supplied jumper completely.
Connect the two sides of the normally closed sensor to the two ter-
minals of the terminal block.
5. INTRINSICALLY SAFE BARRIER WIRING (for normally
open sensor only) Important: Secure area of hazardous conditions
before opening barrier cover or operating sensor contacts.
a. Run Sensor switches wiring through conduit and isolate from the
S1400 terminal block with an explosion-proof barrier.
b. For wiring refer to the following typical wiring diagrams.
CAUTION: Perform the wiring operation with the power source “OFF” and the area made non-hazardous. Make sure the
voltage and current requirements are within the S1400 system ratings. Conduit is required to protect wires from damage.
REFER TO THE SPECIFIC SYSTEM APPLICATION WIRING DIAGRAM SUPPLIED WITH YOUR UNIT.
