General wiring notes1 . Each contact block on the Secondary Terminal Block contains

four independent contacts (Figure A) . A possible 14 terminal blocks will provide 56 contact points for the type NF frame . A possible 24 terminal blocks will provide 96 contact points for the type RF frame .

Figure A. Secondary terminal blocks.

2 . Drawout circuit breakers use Style 67C3246 contact blocks that mount onto an insulated support frame on the cassette .

3 . Fixed mounted circuit breakers use Style 67C3247 contact blocks that mount onto an insulated support frame . The cus-tomer tension connectors are at an angle .

4 . Customer wiring is done using a tension clamp termination on each contact .

5 . Contact blocks are individually mounted and hence contact positions may be empty depending on accessories and options ordered .

6 . The tension clamp terminals will support solid or flexible conduc-tors, #12/4 mm2 through #26/0 .5 mm2 AWG wire and are rated for 600 V, 10 A .

7 . The recommended wire strip length is 10-12 mm (0 .39 - 0 .47 in) .

8 . The tension clamp terminals also support finely stranded conduc-tors with wire-end ferrules and plastic collars DIN 46228/4, rated connection .

9 . The two-point blue plugs house two female crimp contacts (Style 67C3249), with the odd assigned numbers having the coded rib feature on the blue plug (Figure B) .

ote:N Note that the connector plug must be oriented as shown in Figure B before making the connection .

10 . For secondary contacts, odd numbers should be treated as posi-tive voltage for any accessory . This will not apply for AC ratings .

11 . Reference tool for removing leads from secondary contact con-nector plug – 68D3288H01 Extraction Tool (Figure C) .

1 . The Series NRX communication module is a separate device that mounts on a DIN rail bracket . A separate harness is required to remotely mount and wire the module .

2 . The communications module voltage requirement is 24 Vdc ± 10% and should be sourced from a high quality supply (6 watts is the burden of the CAM) .

3 . INCOM communication cable is a two conductor with shield type wire in “daisy chain” configuration . The recommended cable (Belden “Blue Hose” # 9643 or equivalent) has a twisted-pair of wires (# 20 AWG stranded 7 x 28 conductors with PVC insulation) having an aluminum/mylar foil shield with drain wire . The maximum system capacity is 10,000 feet (3048 m) of communications cable and 1,000 devices on the INCOM network . Make sure that the twisted-pair wire is recommended for INCOM network use . Use shielded twisted-pair wire to connect each slave to the INCOM network, daisy-chain style . The polarity of the twisted-pair is not important . Ground the shield at the host computer (device) .

4 . Set the jumper on the module to enable or disable the communications control as desired .

5 . Connectors are UL/CSA rated 300 V, VDE rated 250 V . The recommended connector is Weidmuller # BL 3 .5/90/5 BK, oriented for 90° lead exit . However, other lead orientations are possible . Wire gauge # 18 AWG/0 .82 mm2 .

6 . The final device in the daisy-chain configuration must have a 100 ohm termination resistor installed across terminals #1 and #2 on TB2 .

2 . The communications module voltage requirement is 24 Vdc ± 10% and should be sourced from a high quality supply (6 watts is the burden of the CAM) .

3 . MODBUS communication cable is a three conductor with shield type wire in “daisy chain” configuration . The recommended cable has a twisted-pair of wires (# 24 AWG stranded 7 x 32 conductors with PVC insulation) having an aluminum/mylar foil shield with drain wire . The maximum system capacity is 4,000 feet (1219 m) of communications cable and 32 unit loads on the MODBUS RTU net-work . Make sure that the twisted-pair wire is recommended for MODBUS RTU network use . Use shielded twisted-pair wire to con-nect each slave to the MODBUS RTU network, daisy-chain style . The polarity of the twisted-pair is not important . Ground the shield at the host computer (device) .


5 . Connectors are UL/CSA rated 300 V, VDE rated 250 V . The recommended connector is Weidmuller # BL 3 .5/90/5 BK, oriented for 90° lead exit . However, other lead orientations are possible . Wire gauge # 18 AWG/0 .82 mm2 .

2 . Communication module voltage requirement is 24 Vdc ± 10% and should be sourced from reliable service (6 watts is the burden of the CAM) .

3 . PROFIBUS DP communication cable uses a five conductor flexible cable with shield type wire in “daisy chain” configuration . The maximum cable length depends on Baud rate and can link up to 32 unit loads on the network . Ground the shield at host computer (device) . For further connection information, see PROFIBUS Order No . 2 .142 .

4 . Set jumper on the module to enable or disable communications control as desired .

5 . Connector TB1 is UL/CSA rated 300 V, VDE rated 250 V . Recommended: Weidmuller (BL 3 .5/90/5 BK) oriented for 90° lead exit, but other lead orientations are possible . Wire gauge: #18 AWG / 0 .82 mm2 .

6 . The final device on each end of the network in the daisy-chain configuration must have termination resistors installed as shown on TB2 .

2 . The communications module voltage requirement is 24 Vdc ± 10% and should be sourced from a high quality supply (6 watts is the burden of the CAM) . A shielded CAT5, CAT5e, or CAT6 cable for 10/100 Mb/s ETHERNET is recommended .

3 . The shielded cable is recommended for the best communication reliability in industrial environments . The metal jack provides a ground to the housing on the ETHERNET communications adapter module, which is grounded to the breaker housing via the CAM ground pin . Be sure to ground the breaker housing per the instructions in the breaker IL .


5 . Use shielded ETHERNET cable .

2 . Choose the spring release coil voltage rating as desired if communications is required .

3 . Choose the shunt trip rating to be the same as spring release rating if communication is required .

4 . The control power rating must match the ST and SR coil rating .

5 . Close duration is two seconds on communication activation .

6 . The communication control jumper must be in the enable position for communications opening or closing .

7 . The spring release terminals are 43 & 44 for NF Frame/IZMX16 only . For RF Frame/IZMX40 breakers, the terminals are 55 & 56 .

Legend:

MOT – Motor operator for charging closing spring

ST – Shunt trip

SR – Spring release

Description of operation:

1 . The motor is energized and runs, charges closing spring, and is cut off by switch .

2 . When the spring is charged, the SC closes and the green indicating light will illuminate (if applicable) .

3 . Closing the CS-C contact energizes the spring release coil and closes the circuit breaker . The spring release internal electronics pulse the SR coil and then provides a high impedance circuit . This provides anti-pumping .

4 . When the spring discharges its energy, the motor switch will re-energize the charging motor until the spring is charged again .

5 . To detect the presence of voltage (Health Light), use Omron Red indicator LED Port # C22-L-R-120 for 120 Vac application . For 230 Vac application, use C22-L-R-230 . For 24 Vdc application, use C22-L- R-24 . Remove the white (22 mm [0 .89 in .]) diameter pilot light) Light Diffuser from the assembly to give better indication of voltage present . Activate the push-button to trip the circuit breaker . See Eaton for other voltages .

6 . For secondary contacts, odd numbers should be treated as positive for any accessory . This will not apply to AC ratings .
