1.2.2 Output Connections Before connecting the Battery and/or DC loads, it is recommended to apply AC power and set the configuration for the correct output. See section 2.3 for the configuration instructions. Once the configuration is set, remove AC power from the main feeder breaker to the charger. -
Page 12: Standard Alarms
1.2.4 Standard Alarms Various alarms are included as a standard feature of the ESCR. Only the following alarms include a set of form ‘C’ contacts: High DC Voltage, Low DC Voltage, Charger Failure, and AC Failure. Having contacts available enables the user to connect remote annunciators. - Page 13 Example for AC Fail Alarm Connections: A customer wants a Green Lamp to be illuminated while the AC power is on, and a Speaker to sound when the AC is lost. Using customer provided equipment, they could connect an external power supply, a speaker, and a green lamp.

Page 14: External Temperature Compensation (Option 11W/11Y)
1.2.5 External Temperature Compensation (Option 11W/11Y) The natural voltage of a battery changes as a function of temperature change. As the battery temperature rises, the effective voltage of the battery decreases. Without Temperature Compensation, the battery charger will always produce a set constant output voltage. - Page 15 Figure 11 - S2A-357 Figure 10 - S2A-349 20A ESCR Control Board Top View 40A ESCR Control Board Top View • When an external probe is to be used for temperature compensation, internal temperature compensation must be disabled on the ESCR control circuit board assembly. •...
