Interconnect Diagram
Notes This section provides interconnect diagrams to assist you in wiring the
1394 system. The notes in the table below apply to the interconnect
diagrams on the pages that follow.
Note: Information:
1 For power wiring specifications, refer to Power Wiring Requirementsin Chapter 3.
2 For input fuse and circuit breaker sizes, refer to Circuit Breaker Specifications and Fuse Specificationsin Appendix A.
3 For AC line filter specifications, refer to AC Line Filter Specifications in Appendix A.
4 Contactor coil (M1) needs integrated surge suppressors for AC coil operation. Refer to Contactor (M1) Specifications in Appendix A.
5 Drive Enable input must be opened when main power is removed, or a drive fault will occur. A delay of at least 1.0 second must be observed
before attempting to enable the drive after main power is restored.
6 Cable shield clamp must be used in order to meet CE requirements. No external connection to ground required.
7 Jumper is factory set, indicating grounded system at user site. Ungrounded sites must jumper the bleeder resistor to prevent high electrostatic
buildup. Refer to Determining Your Type of Input Power in Chapter 3 for more information.

ATTENTION
!
Implementation of safety circuits and risk assessment is the responsibility of the
machine builder. Please reference international standards EN1050 and EN954
estimation and safety performance categories. For more information refer to
Understanding the Machinery Directive (publication SHB-900).
9 The recommended minimum wire size for wiring the safety circuit to the contactor enable connector is 1.5 mm
2
(16 AWG).
10 If an external shunt resistor is used, remove the jumper between INT and COL.
11 There is no internal shunt resistor in the 22 kW system module. An external shunt resistor module (1394-SRx Ax) must be used.
12 The thermal switch and brake circuits are a source of conducted noise. Isolation from customer control devices may be required. A separate 24V
dc supply or relay can be used. Axis modules (Series C or later) include a thermal switch and motor brake filter to eliminate the need for a
separate 24V dc supply.
13 Use a flyback diode for noise suppression of the motor brake coil. For more information, refer to System Design for Control of Electrical Noise
Reference Manual (publication GMC-RM001x-EN-P).
14 For motor cable specifications, refer to Motion Control Selection Guide (publication GMC-SG001x-EN-P).
15 User supplied auxiliary contact is recommended. Use safety rated, mechanically linked contactor for M1.
