Page 2: Important Safety Instructions
There are no serviceable parts for this controller. Do disassemble or attempt to repair the controller. Disconnect the solar module and fuse/breakers near to battery before installing or adjusting the PWM1020CC-DB. Install external fuses/breakers as required. allow water to enter the controller. -
Page 3: Battery Safety
Battery Safety Use only sealed lead-acid, flooded, or gel batteries which must be deep cycle. Explosive battery gases may be present while charging. Be certain there is enough ventilation to release the gases. Be careful when working with large lead acid batteries. Wear eye protection and have fresh water available in case there is contact with the battery acid. -

Page 8: Installation
There should be at least 100mm of clearance above and below the controller to allow for cooling. If mounted in an enclosure, ventilation is highly recommended. WARNING: Risk of explosion! Never install the PWM1020CC-DB in a sealed enclose with flooded batteries! Do not install in a confined area where battery gas can accumulate. Step 1:... - Page 9 Wiring Recommended tools to have before installation: Flathead Screwdriver Multi-Meter WARNING: Connect battery terminal wires to the charge controller FIRST then connect the solar panel(s) to the charge controller. NEVER connect solar panel to charge controller before the battery. CAUTION: Do not over-torque or over tighten the screw terminals.
- Page 10 Battery Connect Battery 1: Refer to Figure 4, Connect the negative terminal of Battery 1 to the negative terminal of the charge controller under the Battery 1 logo. Then connect the positive terminal of Battery 1 to the positive terminal of the charge controller under the Battery 1 logo. Connect Battery 2: Repeat the process described in last step for Battery 2.
- Page 11 Solar Panels Connect the solar panel(s): Connect the negative PV lead of the solar panel to the negative terminal of the charge controller under the solar array logo. Then connect the positive lead of solar to the positive terminal of the charge controller under the solar array logo. Make sure the solar module(s) voltage and current do not exceed the ratings of the charge controller.
- Page 12 Temperature Sensor (if applicable) Connect the Remote Temperature Sensor (Optional): If you purchased the remote temperature for your batteries, you can connect it in the remote temperature terminals depicted in Figure 4. If you are not planning on using this sensor, you can skip this step. Note: When the RTS is not present, the controller will calculate the data from the local temperature sensor.
