Interconnecting Cables

Interconnecting cable conductor size is dependent upon the distance between the control, switches, and potential transformers. Maximum lengths of various cable combinations for No. 18 through No. 12 AWG conductors are shown in Table 2. The longest combination for the particular installation will determine the minimum conductor size. All cables are to be the same conductor size.

Note: If the control is equipped with the fault block accesso- ry, see Table 3 for additional cable length limitations.

On the switch end, the cables are wired to connector plugs provided as standard with the switches. On the S control end, the cables are wired either directly to terminal blocks in the control or to connector plugs provided with the Plugs and Receptacles accessory. Figure 9 shows the location of the accessory plugs and receptacles in the bottom of the control cabinet. See the appropriate switch installation manual for the location of the plugs and receptacles on the switch.

Switch Cable

A conductor cable is required between the S control and each high-voltage switch to operate the switches. This cable is wired to a socket plug at the switch end and to either a plug or TB1 at the control end. Pin identification, and cable OD and maximum conductor size accommodated by the plugs are shown in Figures 10 and 11.

Potential Transformer Cable

A four-conductor cable is required between the S control and the potential transformers to transmit source voltage intelligence and to supply operating power for the control. This cable is wired to a five-pin socket plug or TB2 at the control end. Pin socket identification, cable OD, and maximum conductor size accommodated by the plugs are shown in Figure 12.

Note: Connectors are not supplied for the transformer end of the cable.
