3.5 Cooling Control and Condition Alarm Connections
Figures 3.13 a&b illustrate the connections of the form C dry relay contacts for
both NEMA and panel mount models. Figure 3.13b shows these connections on
panel mount models and 3.13a for NEMA models, Each relay is capable of
carrying 10 Amps at 230 VAC. Configure these contacts for 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 number
of factors including voltage applied and the type of load. In general, there is
a higher tendency for contacts to become welded shut at higher voltages.
Therefore, protection devices, such as MOVs are highly recommended if
these contacts will be required to break more load current than that shown
in the Specifications.
