6 5mm Allen head wrench to remove enclosure lid (included with gas Detector ). 2. Flat-head screwdriver maximum 3/16 (5 mm) width for terminal block connections (included with gas Detector ). 3. Adjustable wrench for conduit or cable gland connections (not included). It is not necessary to seal the Model S4000C housing to maintain its explosion-proof integrity; however, conduit runs containing wires attached to the Model S4000C s relay contacts must be sealed. Information on Class I location seals can be found in the NEC, Article 501-5. Figure 1: Outline and Mounting Dimensions Terminal Connections The terminal blocks (TB) are located inside the housing and can be accessed by removing the cover. A label on the inside of the housing cover provides details of all the terminal connections. WARNING: Do not connect +24 VDC to TB1. Damage to the electronics, or sensor may result. It is recommended that a three-wire (red, black, white) shielded cable be used for making power and output signal connections on the Model S4000C .

7 The Spring Type terminal block accepts 14 AWG to 20 AWG and the Screw Type terminal block accepts 12 AWG to 18 AWG stranded or solid wire. Each wire should be stripped before wiring the Model S4000C Intelligent Sensor. To connect wiring to the Spring Type terminal block, insert a screwdriver into the orange tab and press down (Figure 2), opening the terminal. Insert the wire into the terminal 1 S4000C 2 and release the orange tab, clamping the wire in the terminal. Check the hold of the wire by GENTLY tugging it to ensure it is locked in.

8 To connect wiring to the Screw Type terminal block, (Figure 3) use a screwdriver to loosen the top screw counter clock wise. Insert the wire into the terminal and tighten the top screw clock wise. Check the hold of the wire by GENTLY tugging it to ensure it is locked in. Figure 2: Spring Type Terminal Block Operation Figure 3: Screw Type Terminal Block Operation NOTE: Power must remain disconnected until all other wiring connections have been made. The maximum distance between the Model S4000C and the power supply is 3430 feet or 1040 meters (each cable run should be as short as possible). See Section for cable length specifications. Connect +24 VDC to TB2, position 9. Connect the ground or common to TB2, position 8. The instrument is now ready to operate. Please consult the Manual for more information on the instrument s many features. NOTE: If you have any problems in the set-up or testing of the Detector , please refer to the Trouble Shooting Section , or call the factory direct.
