20 V6.70 201310173.5 Cooling Control and Condition Alarm ConnectionsFigures 3.13 a&b illustrate the connections of the form C dry relay contacts forboth NEMA and panel mount models. Figure 3.13b shows these connections onpanel mount models and 3.13a for NEMA models, Each relay is capable ofcarrying 10 Amps at 230 VAC. Configure these contacts for cooling control, hightemperature alarms, or LTC condition alarm. Programming these contacts will bediscussed 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 MOVs are highly recommended ifthese contacts will be required to break more load current than that shownin the Specifications.Figure 3.13a: RelayOutputs – NEMANote that all terminationsmay not be presentdepending on the optionspurchased.Figure 3.13b: RelayOutputs – PanelNote that all terminationsmay not be presentdepending on the optionspurchased.12POWER34AuxCTCOMTMPREFGROUNDSHIELDTB3TB2TB1BCOMTMPREFANALOG OUT+ -A1+ -A2ALARMNCOUT4C NO NCOUT3C NO NCOUT2C NO NCOUT1C NONCOUT5C NONCOUT6C NO TB1ACOMTMPREFA BRS485Rx TxGNDRptTxRx5671234IN1 IN2 TB4TB5+ -A3BUSYOK1234IN4 IN39101112IN14 IN135678IN12 IN1134IN1012IN95678IN6 IN59101112IN8 IN716 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1CT1CT2CT3CT4CT5CT6CT7CT8TB6TB7 TB81234 TB3TB2Aux CT PowerTB1OUT5OUT6 OUT4 OUT2OUT3 OUT1TB1ATB5IN2IN12 1Probe 1 Probe 2 Alarm101112 789 56 4Probe 33IN 3IN 4IN 5IN 6IN 7IN 8TB7IN 9IN 10IN 11IN 12IN 13IN 14TB6
