Battery Power Applications:
Units shipped with internal battery option do not have the battery connected during
shipping.
CAUTION - Lithium Primary (LiP non-rechargeable) internal battery:
DO NOT
connect external voltage directly to battery terminals or to supply/solar terminals as
this battery is
NOT rechargeable
and damage may result.
CAUTION - Lithium Iron Phosphate (LFP rechargeable):
DO NOT connect
external voltage directly to battery terminals as this may result in damage or
overheating of battery pack.
To connect the internal battery:
·
Remove the battery holder by removing the two Philips screws and battery
bracket.
·
Locate the battery connector located at the top
right of battery as shown in picture.
·
For internal battery connect the battery by
plugging battery cable connector onto the two
pin connector on circuit board located to right
of internal/external selection link, using correct
orientation (keyed).
·
The PWR/OK LED green flash every 10 seconds in normal operation. See unit
configuration on reverse side of this document.
