CAUTION:
Motor Thermal Overload protection
must be provided, either bv motor thermoswitch,
external motor overload relav, or inverter electronic
thermal overload.
CAUTION:
Because the ambient temperature
affects inverter life and
do not install
the inverter in anv location that exceeds the allowable
temperature. Leave the ventilation cover attached for
temperatures of 40 deqrees C or below, and remove
the cover for temperatures between and dearees
C. If the cover needs to be removed, another
of enclosure
be required for
purposes.
The inverter should not be operated when the
ambient temperature is above 50 dearees C.
CAUTION:
Do not connect a phase advance
in the output wires. The
and
inverter will overheat and be
due to har-
monics.
CAUTION:
The control circuit terminal wirinn should
be kept as far awav as possible from the main power
wirinq to prevent operational error due to noise inter-
ference. Never install both
of
in the same
duct or conduit. (A separation distance of
centi-
meters 14 inches1 or more is recommended.) If the
control circuit wiring must cross the main power
inn, it should cross at a
(see Fiaure
CAUTION:
Use shielded or twisted wire for the
control circuit wirina
should be as short as
possible, i.e. 20 meters
feet1 or less). (Connect
outer
of the shielded wires to the inverter
around terminal and leave the other end uncon-
nected, but taped.)
CAUTION:
Install a suppressor in parallel with any
relavs or solenoid
coils, etc. that mav be close to
the inverter or used with the inverter.
NOTE: Always read the complete instructions prior to
applyingpoweror troubleshooting
equipmentand
follow al/procedures step by step.
NOTE: The motor chassis should be grounded to
earth ground through a separate ground lead from all
other equipment ground leads to prevent noise coupling.
NOTE: Readandheedall WARNING, CAUTION, and
NOTE labels posted on the equipment.
