Figure 3.14b shows these connections on NEMA 4 models.Each relay is capable of carrying 10 Amps at 230 VAC. Configure these contactsfor cooling control, high temperature alarms, or LTC condition alarm.Programming these contacts will be discussed in Section 4.9.NOTE: The ability for these contacts to break its load is based on a numberof factors including voltage applied and the type of load. In general, there isa higher tendency for contacts to become welded shut at higher voltages.Therefore, protection devices, such as MOV’s are highly recommended ifthese contacts will be required to break more load current than that shownin the Specifications.
