ArmorConnect Power Media Description

Encl

The ArmorStart Power Media offers both three-phase and control power cable system of cordsets, patchcords, receptacles, tees, reducers and accessories to be utilized with the ArmorStart Distributed Motor Controller. These cable system components allow quick connection of ArmorStart Distributed Motor Controllers and reduce installation time. They provide for repeatable, reliable connection of the three-phase and control power to the ArmorStart Distributed Motor Controller and motor by providing a plug and play environment that also avoids system mis-wiring. When specifying power media for use with the ArmorStart Distributed Motor Controllers (Bulletins 280G/281G and 284G) use only Bulletin 280 ArmorConnect™ power media.

Configuration of the 1732DS-IBXOBV4 Safety I/O

Note: To comply with TÜV, the 1732DS-IBXOBV4 Safety I/O module

must be configured as indicated below:

Configure the output that is connected to the I/O output cable assembly for:

• Dual (bipolar mode)

• Safety Pulse Test

Configure the input that is connected to the I/O Input cable assembly as follows:

• Channel = Single

• Mode = Pulsed Test Input from test output X

• Source = Pulsed output from X

Safety PLC Program The program must:

• Force the output contactors to the open state when a safety-related stop is demanded.

• Force the output contactors to remain in the open state if the SM feedback is open after a safety-related stop is executed (see Notes).

Note: The program must inhibit the contactor closure to satisfy safety

Category 4 of 13849-1.

Note: The SM feedback logic should be implemented only after a

safety-related stop for the Bulletin 284G controllers. It should be ignored during normal operation. One of the series contactors is used for the normal stop/start function for these controllers. Therefore, a malfunctioning contactor circuit cannot be distinguished from a normal running state.

Branch Circuit Protection Requirements for ArmorConnect™ Three-Phase Power Media

Group Motor Installations for USA and Canada Markets

Wiring and Workmanship Guidelines

When using ArmorConnect Three-Phase Power Media, fuses can be used for the motor branch circuit protective device, for the group motor installations. The recommended fuse types are the following: Class CC, T, or J type fuses, (100 A max.). For additional information, see the ArmorStart User Manual. A circuit breaker can be used for the motor branch protective device, for the group motor installations when using only the following ArmorConnect power media components: 280-M35M-M1, 280-M35F-M1, 280-T35, and 280-PWRM35*-M*. For additional information, see the ArmorStart User Manual.

The ArmorStart Distributed Motor controllers are listed for use with each other in group installations per NFPA 79, Electrical Standard for Industrial Machinery. When applied according to the group motor installation requirements, two or more motors, of any rating or controller type, are permitted on a single branch circuit. Group Motor Installation has been successfully used for many years in the USA and Canada.

In addition to conduit and seal-tite raceway, it is acceptable to utilize cable that is dual rated Tray Cable, Type TC-ER and Cord, STOOW, for power and control wiring on ArmorStart installations. In the USA and Canada installations, the following guidance is outlined by the NEC and NFPA 79.

In industrial establishments where the conditions of maintenance and supervision ensure that only qualified persons service the installation, and where the exposed cable is continuously supported and protected against physical damage using mechanical protection, such as struts, angles, or channels, Type TC tray cable that complies with the crush and impact requirements of Type MC (Metal Clad) cable and is identified for such use with the marking Type TC-ER (Exposed Run)* shall be permitted between a cable tray and the utilization equipment or device as open wiring. The cable shall be secured at intervals not exceeding 1.8 m (6 ft) and installed in a “good workman-like” manner. Equipment grounding for the utilization equipment shall be provided by an equipment grounding conductor within the cable.

*Historically cable meeting these crush and impact requirements were designated and marked “Open Wiring”. Cable so marked is equivalent to the present Type TC-ER and can be used.
