Chapter 4 Maintenance
There are no user-serviceable parts inside the controllers. Do not attempt
to open the controller. Or will void warranty. However, cleaning the
controller exterior periodically should be necessary.
The controller is inherently a high power device. When working with any
battery powered vehicle, proper safety precautions should be taken. These
include, but are not limited to, proper training, wearing eye
protection, avoiding loose clothing and jewelry, and using insulated tools.
4.1
Cleaning
Although the controller requires virtually no maintenance after properly
installation, the following minor maintenance is recommended in certain
applications.
• Remove power by disconnecting the battery, starting with battery
positive.
• Discharge the capacitors in the controller by connecting a load (such as a
contactor coil, resistor or a horn) across the controller’s B+ and B-
terminals.
• Remove any dirt or corrosion from the bus bar area. The
controller should be wiped with a moist rag. Be sure it is dry before
reconnecting the battery.
•
Make sure the connections to the bus bars are tight. Use two wrenches
for this task in order to avoid stressing the bus bars; the wrenches should
be well insulated.
