Warning Markings
GENERAL:
These devices are open type and/or Enclosed Type 1 (when employing accessory Type 1 Chassis Kit) AC Inverters with
three phase input and three phase output. They are intended to be used in an enclosure. They are used to provide
both an adjustable voltage and adjustable frequency to the ac motor. The inverter automatically maintains the
required volts-Hz ration allowing the capability through the motor speed range.
(1) “Use 60/75

C CU wire only” or equivalent.
For models SJ700D-055H, SJ700D-075H, SJ700D-110H.
(2) “Use 75

C CU wire only” or equivalent.
For models SJ700D series except for SJ700D-055H, SJ700D-075H, SJ700D-110H.
(3) “Suitable for use on a circuit capable of delivering not more than 100,000rms symmetrical amperes,
240V maximum”. For models with suffix L.
(4) “Suitable for use on a circuit capable of delivering not more than 100,000rms symmetrical amperes,
480V maximum”. For models with suffix H.
(5) “Install device in pollution degree 2 environment”
(6) “Maximum Surrounding Air Temperature 45

C (only for Models SJ700D-550L VT Amps) or 50

C (for Models
SJ700D series without SJ700D-550L VT Amps)” for without Type 1 kits or “Maximum Ambient Temperature 45

C
(only for Models SJ700D-550L VT Amps) or 50

C (for Models SJ700D series without SJ700D-550L VT Amps)” for
with Type 1 kits or equivalent.
(7) “CAUTION - Risk of Electric Shock - Capacitor discharge time is at least 10 min.”
(8) ”Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the NEC and any additional local codes”
(9) “Solid State motor overload protection reacts with max. 120% of FLA”.
