The Cautions, Warnings, and instructions in this section summarize the procedures necessary to
ensure an inverter installation complies with Underwriters Laboratories
The SJ700 series inverter family is an open-type and/or Enclosed Type 1 (when employing
2
accessory Type 1 Chassis Kit) AC inverter with 3-phase input and 3-phase output. The inverter
are intended for use in an enclosure. The inverter supplies adjustable voltage and adjustable
frequency to an AC motor. The inverter can automatically maintain a constant volts/Hz ratio to
enhance the motor capability throughout its entire speed range.
WARNING: Use 65/75°C Cu wire only or equivalent. For SJ700 series except SJ700-300Lxx
and SJ700-370Lxx.
WARNING: Use 75°C Cu wire only or equivalent. For SJ700-300Lxx and SJ700-370Lxx.
WARNING: Suitable for use on a circuit capable of delivering not more than 100,000 rms
symmetrical amperes with 240 V maximum. For models with suffix L (200V class).
WARNING: Suitable for use on a circuit capable of delivering not more than 100,000 rms
symmetrical amperes with 480 V maximum. For models with suffix H (400V class).
WARNING: The inverter must be installed in an environment that is rated for at least Pollution
Degree 2 or equivalent.
WARNING: The ambient temperature must not exceed 50°C.
WARNING: The capacitor discharge time is 10 minutes or more. (Caution: Care must be taken
to avoid the risk of electric shock.)
WARNING: Each model of the inverter has a solid-state overload protection circuit or an
equivalent feature for the motor.
