SBOOST II User Guide

Version 1.1 June 2015

Auto-reverse Operation

The SBOOST II can be configured for auto reverse operation, e.g., to supply
power to a reverse loop or wye formation as a separate power district.

To enable or disable auto-reverse operation you must open the casing of the
SBOOST II and fit or remove a jumper link.

To open the casing, prize the two halves apart by inserting a small flat bladed
screwdriver in the slots and twisting gently, as shown below.

Remove the small jumper from its parking location and re-fit it to bridge the
pins of J1.
