Chapter 2 Installation and Wiring
at 480Y/277 VAC maximum when protected by Cat. No.140U-D6D3-C30
circuit breaker, refer to the Specifications
, Chapter 6.
Fusing:
Where ArmorStart LT is used with ArmorConnect — suitable for use on a
circuit capable of delivering not more than 10000 RMS Symmetrical Amperes
(SCCR) at 480/277 V AC maximum when protected by 40 A CC, J, and T
class fuses, refer to the Specifications
, Chapter 6.
Electrical Wiring
ArmorStart LT EtherNet/IP utilizes 24V DC control power for communications
and I/O. The control power terminal connections are labeled A1, A2, and A3.
Switched power (A1) will supply outputs and motor control. Unswitched
power (A3) will supply logic power, communications, and sensor inputs.
WARNING: The total circuit impedance including each cable assembly's own
impedance, must be low enough to ensure any short-circuit or ground fault
current that can flow through any assembly, will be large enough to operate the
magnetic trip of the Cat. No. 140U-D63-C* circuit breaker. Refer to NFPA 70 and
NFPA 79 or your local electrical code for guidance in coordinating over current
protective devices and the circuit being protected.
IMPORTANT
EtherNet/IP is an unpowered network, therefore if device status is important,
the A3 terminal must have an unswitched power source.
