WARNING
Working in the vicinity of a Lead-Acid battery is dangerous. Batteries generate explosive gases during
normal operation. For this reason, it is of utmost importance that you follow the instructions each time
you use the charger.
CAUTION
Only use the Battery Charger for charging Standard Automotive Lead Acid, Calcium Content, GEL, AGM,
SLI, Deep Cycle or Lithium Iron Phosphate type 12 V batteries.
When charging a battery, ensure settings at the Battery Setup menu on the Remote Monitor are correct
for the type of battery under charge. Charging a battery with the wrong profile may cause The Manager30
to indicate a fault or give misleading results and could result in damage to the battery. Noticeable
oscillations between Boost and Absorption stages indicate incorrect choice of battery type. Check and
adjust battery type. If you are unsure of the battery type or settings to use, set The Manager30 to the Gel
profile.
Figure 2.5.1 and 2 Figure 2.5.2 show standard wiring for batteries in series and parallel respectively.

To ensure that all batteries are equally charged, loads and The Manager30 should be connected with
ground and 12 V power connected diagonally opposite across all batteries as shown in Figure 2.5.2.
The Ah rating needs to be setup when prompted on first start up (Refer Section 3.3), these settings can
also be modified in the “Advanced Settings” menu (Refer Section 3.5). To calculate Ah rating of batteries
in parallel simply add the rating of each battery in the bank together. For example, three batteries with
an Ah rating of 100 Ah each will yield a total of 3 × 100 Ah or 300 Ah. Batteries connected in series will
assume the lowest Ah rating of the batteries in the bank. For example, 2 batteries in the bank, one is
50 Ah the other 100 Ah. When connected in series the Ah rating is 50 Ah.
