Curtis 1298 Manual, OS 11
You will need to take steps during the design and development of your
end product to ensure that its EMC performance complies with applicable
regulations; suggestions are presented in Appendix B.
The1234/36/38 controllers contain ESD-sensitive components. Use
appropriate precautions in connecting, disconnecting, and handling the con
-
troller. See installation suggestions in Appendix B for protecting the controller
from ESD damage.
2 — INSTALLATION & WIRING
Working on electrical systems is potentially dangerous. You should
protect yourself against uncontrolled operation, high current arcs, and
outgassing from lead acid batteries:
UNCONTROLLED TRACTION OPERATION — Some conditions could cause the
traction system to run out of control. Disconnect the traction motor or
jack up the vehicle and get the drive wheels off the ground before attempt
-
ing any work on the traction motor control circuitry.
UNCONTROLLED HYDRAULIC OPERATION — Some conditions could cause the
hydraulic system to run out of control. Disconnect the pump motor or
make sure the hydraulic system has enough room to operate before at
-
tempting any work on the pump motor control circuitry.
HIGH CURRENT ARCS — Batteries can supply very high power, and arcing can
occur if they are short circuited. Always open the battery circuit before
working on the motor control circuit. Wear safety glasses, and use properly
insulated tools to prevent shorts.
LEAD ACID BATTERIES — Charging or discharging generates hydrogen gas,
which can build up in and around the batteries. Follow the battery man
-
ufacturer’s safety recommendations. Wear safety glasses
