IDENTIFYING THE DRIVE BY PART NUMBER —
Each AC drive can be identified by its assembly number. See
Fig. 36. This number appears on the shipping label and on the
drive’s nameplate. LiquiFlo 2.0 AC drives comprise an input
components section and a power module section.
Each LiquiFlo™ 2.0 AC power module can be identified by
its model number. See Fig. 36. This number appears on the
shipping label and on the power module’s nameplate. Power
ratings are provided in Table 10.

WARNING
DC bus capacitors retain hazardous voltage after input
power has been disconnected. After disconnecting input
power, wait 5 minutes for the DC bus capacitors to dis-
charge and then check the voltage with a voltmeter to
ensure the DC capacitors are completely discharged before
touching any internal components. Failure to observe this
precaution could result in severe bodily injury or loss of
life.
WARNING
The drive can operate at and maintain zero speed. The user
is responsible for assuring safe conditions for operating
personnel by providing suitable guards, audible or visual
alarms, or other devices to indicate that the drive is operat-
ing or may operate at zero speed. Failure to observe this
precaution could result in severe bodily injury or loss of
life.
CAUTION
The drive contains ESD (Electrostatic Discharge) sensitive
parts and assemblies. Static control precautions are
required when installing, testing, servicing, or repairing the
drive. Erratic machine operation and damage to, or destruc-
tion of equipment can result if this procedure is not
followed.
