Refer to the section , Using A Shorting Bar. 2-36 VersaMax Modules, Power Supplies and CarriersUser Manual GFK-1504N 2 For example, a 16-point module might use 3 Auxiliary Terminals for 4-wire devices as displayed in the following figure. CLASS I ZONE 2 Ex nA IIC T4 OC Ta Ex nV II T4 Demko N Point Connections Common Connections +V Connections -V Connections Auxiliary Terminals accommodate current levels up to 8 A and voltage up to 264 V AC. Voltage transients up to 300 V AC will not cause damage. Installing Auxiliary Terminals Auxiliary Terminals are installed by inserting the tabs into the slots on the Carrier or Interposing Terminals and pressing downward. Screws can be inserted through the panel-mount holes for added stability if needed. Auxiliary Carriers must be installed on the Carrier or Interposing Terminals before connecting field wiring. Wire Specifications for Auxiliary Terminals Wire specifications depend on the terminal type. For box-type or spring type terminals, each terminal accommodates one solid or stranded AWG #14 (avg. 2.1mm2 cross section) to AWG #22 (avg. 0.36mm2 cross section) wire, or two wires up to AWG #18 (avg. 0.86mm2 cross section). For barrier-type terminals, each terminal accommodates one or two solid or stranded wires from AWG #22 (avg. 0.36mm2 cross section) to AWG #14 (avg. 2.1mm2 cross section). Use copper wire rated for 90 deg C. When inserting two wires in the same position, the wires must be the same size and type (solid or stranded). GFK-1504N Chapter 2 Installation 2-37 2 Using Shorting Bars Shorting Bars (part number IC200ACC303, quantity 2) can be a cost-effective solution for providing additional bussed terminals for modules that include only one board. The shorting bar has a maximum current-carrying capacity of 2 Amps per point. Refer to the individual module descriptions to determine whether a shorting bar can be used for a particular module. The following figures illustrate the use of a Shorting Bar on a 2-row or 3-row carrier to provide extra field wiring connections for an module. Example Connection for Carriers with Two Rows of Terminals A Shorting Bar must be installed directly on the carrier before installing the module.
