1 EC480 Control Panel Replacement

1.1 Installation Process

• Unpack the new control panel.

• Remove the decorative bezel from the control panel, by pulling in the direction of the BLUE

arrows.

• Remove the two screws that hold the panel in place.

• Carefully lift the panel forward to gain access to the rear circuit board of the control panel.

• Disconnect the 6-way connector

• Place the old panel to one side.

• Connect the new panel to the 6-way connectors.

• Check that all connectors are firmly seated.

• Refit the control panel using the original screws and refit the bezel.

1.2 Current sensor re-calibration

Each EC480 control panel needs 'calibrating' to match the current sensor fitted within the EC500PSU.

The procedure is as follows:

• If you have a solar panel fitted, either unplug the panel at the base of the PSU or carry out

this procedure at night.

• With the charger turned off, and the power turned off at the control panel (no LED’s on)

• Scroll down ▼ to the active battery screen

• Hold down the select button ◄ (left arrow) until 'calibrating….' appears then release the

button

• The current reading should now be correct.
