Alternative 6, 7 Alternative ------
Note: 1. Extension cable, Order number: 7202-F94009-BK or 7202-RG-58
1.) If temperature probe is not used, the Order No. is 7202-RG-58.
2.) If temperature probe is used, the Order No. is 7202-F94009-BK.
2. If temperatures probe 8-26-3(NTC30K) or 8-26-8(PT1000) is used for two-wire distribution, the
black wire terminal should be forbidden.

Note: 1. The black wire on the temperature probes of 8-26-3(NTC30K) or 8-26-8(PT-1000) is used as special
wire as solution ground rod which is to be connected at terminal 2.
2. The extension cable, Order Number: 7202-F94009-BK, is for system that apply a temperature probe or
solution ground rod.
