Segway SE-3 Patroller - Power Interface

99
Overview
The Power Interface is composed of the Power Interface Board (PI Board), the
Charger, and the Electronics Shield. These components are mounted on an
aluminum block for thermal dissipation.
All of the electronic components of the SE-3 Patroller connect to the PI Board via
cable harnesses. The Battery Module connects directly to the PI Board.
When to Replace
Replace the Power Interface Board or Charger when troubleshooting indicates that
it is malfunctioning.
Replace fuses when they blow.
NOTICE
If any fuse blows — other than FH9, 12V Accessory Supply — a deeper issue may
exist. Contact Segway Technical Support (see page iv).
Safety
WARNING!
Wait two minutes after removing the Battery Module before removing the
Electronics Shield. This is how long it takes for the capacitors on the PI Board to
self-discharge. Touching the PI Board before the capacitors have fully discharged
could result in electric shock.
CAUTION!
Use ESD best practices to avoid damaging the PI Board and other electronics.
