Battery connection procedure
Warning
Specific care and attention must be taken when making the battery connections. Correct polarity must be confirmed with a multimeter before connection. Connecting a battery with incorrect polarity will destroy the Multi RS19 Solar and is not covered by warranty.
Connect the negative battery cable first then connect the positive cable.
Push the Amphenol SurLok cable plug onto the receptacle on the Multi. Apply firm pressure until you hear a click, then the plug is latched onto the receptacle.
