battery to spark or might short-circuit the battery or other 

electrical parts that may cause an explosion. 

12. Remove personal metal items such as rings, bracelets, 

necklaces, and watches when working with batteries. A 

battery can produce a short-circuit current high enough to 

weld a ring or the like to metal, causing a severe burn.

A SPARK NEAR A BATTERY MAY CAUSE THE BATTERY 

TO EXPLODE. TO REDUCE THE RISK OF A SPARK NEAR A 

BATTERY WHEN CONNECTING THE BATTERY INSTALLED 

IN A VEHICLE TO THE BATTERY CHARGER, ALWAYS DO 

THE FOLLOWING:

Always wire the Output Connector before connecting it to the 

Battery Charger. During connection of the unit, the Battery 

Output (positive) must be connected first, followed by the 

Ground (chassis) terminal. The chassis connection should 

be made away from the battery and fuel lines. DC Input 

(positive) should be connected last. Once all connections are 

wired to the Output Connector, plug the connector into the 

Main Unit.
When disconnecting the Battery Charger, remove the AC 

Connector first, followed by the CAN connection then the 

Output Connector from the Main Unit. The DC Input should 

be disconnected next, followed by the Ground (chassis) 

connection, then the Battery Output connection if complete 

removal is necessary.

PERSONAL SAFETY PRECAUTIONS

To assist with the safe operation and use of the Battery 

Charger:

a)  Consider having someone close by to come to your aid when 

you are using the Battery Charger.

b)  Have plenty of fresh water and soap nearby in case battery 

acid contacts skin, clothing, or eyes.

c)  Wear complete eye protection and clothing protection. Avoid 

touching eyes while working near a battery.

d)  If battery acid contacts your skin or clothing, remove the 

affected clothing and wash the affected area of your skin 

immediately with soap and water. If battery acid enters your 

eye, immediately flood the eye with running cold water for at 

least 10 minutes and seek medical assistance immediately.

e)  To improve user safety it is recommended to control the 

charger and monitor the charging process using the remote 

away from the vicinity of the battery being charged.

NOTICE

1.  Do NOT connect computers or IT equipment to the Charger 

front panel connector or remote. Damage may occur.

2.  It is recommended to leave the remote connected to the 

base unit at all times.

3.  The Main Unit must be fixed using suitable screw 

mounts. Failure to adequately mount the unit, such as 

using adhesives to mount the unit will result in unreliable 

operation of the charger.

4.  When using the charger in Storage mode, make sure that 

there is a valid charging source and that all loads are 

disconnected from the house battery. Failure to do so may 

cause the house battery to be under charged, give false 

readings on the State of Charge indicator and possibly cause 

damage to any loads connected.

5.  A partially shaded panel (or low-light conditions such as 

dawn or dusk) will increase the target solar panel voltage 

level to match the maximum power point. In this situation 

solar will be selected as a source however little or no current 

will be flowing into the battery.

6.  Modification of the ‘Advanced Settings’ menu items affect 

the way the Battery Charger responds to charging situations. 

Modification of these settings may result in the Battery 

Charger not functioning at 100% of its capacity. These 

settings should only be modified if absolutely necessary and 

when the effects of the changes are 100% understood.

7.  Touring mode will achieve its best charge level if a Storage 

mode charge has been recently performed.

8.  It is the installers responsibility to ensure their installation 

complies with any applicable legal and regulatory 

requirements.
