Precautions
1.
Before using the charge/load controller, read all the instructions and cautionary markings on the
charge/load controller, the batteries and the photovoltaic panels.
2.
Do not attempt to repair the controller. Incorrect re-assembly may result in a risk of electric shock or
fire.
3.
To reduce risk of electric shock, disconnect all wiring before attempting any maintenance or cleaning.
Turning off controls will not reduce this risk. PV panels produce power when exposed to light – cover
them with opaque material before servicing.
4.
Working in Vicinity of a Lead Acid Battery is dangerous. Batteries generate EXPLOSIVE gases during
normal operation. Provide ventilation to outdoors from the highest point of the battery compartment.
5.
This charge/load controller is intended to be used with a battery supply of 12 VDC nominal voltage.
6.
Be extra cautious to reduce the possibility of dropping a metal tool onto batteries. It might spark or
short-circuit batteries or other electrical parts that may cause explosion. Cover wrench handles with
plastic tape or vinyl dip coating material.
