WARNING: Under certain conditions, the motor may automatically restart after a fault has
stopped it. Make sure power to the drive has been disconnected before approaching or servicing
the equipment. Otherwise, serious injury may occur.
CAUTION: Use caution when applying power to the main input terminals of the unit. If the drive
is programmed to allow automatic restarts, the drive will initialize in AUTO mode and the motor
load may start as soon as the drive is energized.
CAUTION: The AC motor load must be connected directly to the output terminals of the drive.
Do not install relays, disconnect switches, or wire nuts between the drive and the motor load.
CAUTION: Before the motor is connected to the output terminals, check all output lines for line-
to-ground faults using a megger. There is a direct path through the drive circuitry for ground fault
currents that can be triggered when power is applied to the input terminals, even though the
output switches are not activated. These currents can cause serious damage to drive circuitry
and are not covered under warranty.
CAUTION: Before touching any printed circuit board, place a hand on a bare metal surface of
the unit to discharge any static electricity. Electrostatic discharge (ESD) can damage printed
circuits and their components.
CAUTION: When the parameter, 1.2.1 ENABLE RESTARTS, is set to YES, the drive will
energize in AUTO mode. The motor load may automatically run as soon as the drive is
energized. To stop the motor, push the STOP/OFF key until the display indicates MANUAL or
OFF, or open AUX1 or AUX2. The RUN and STOP keys only work when in MAN mode. Refer
to the section on Keypad and Display for instructions on operating the keypad.
CAUTION: Operating the system in MANUAL mode on the keypad overrides remote signals
from any remote controls. Operating the system in this mode may lead to dangerous pressures
in closed plumbing systems.
