OWNER'S MANUAL
LINK 20
INSTALLERS: PLEASE LEAVE THIS MANUAL WITH THE OWNER.
IT CONTAINS IMPORTANT OPERATING INFORMATION.
APPLICATIONS: The Link 20 provides instrumentation of two banks of
batteries. The Link 20 does not control an inverter/charger. For installations
involving a Freedom inverter/charger and two battery banks, the Link 2000
is recommended. If a Freedom inverter/charger and one battery is anticipated,
the Link 1000 is recommended. For instrumentation of a single battery bank
with no inverter/charger controls, the Link 10 is ideal.
OPERATION: Instructions on how to operate your Link 20 begin on page 4
of this manual.
INSTALLATION: This manual contains easy to follow installation instructions
beginning on page 32.
WARRANTY ISSUES: Warranty issues will be resolved directly through Heart
Interface. Please do not route warranty issues through your dealer.
