Safety <strong>Instruction</strong>s<br />
Precautions Concerning Compliance with UL and CUL Standards<br />
(Standards to be met: UL508C and CSA C22.2 No. 14-05)<br />
The <strong>SJ700</strong> series inverter is an open-type AC inverter with 3-phase input and output, intended for use in<br />
an enclosure. The inverter supplies both voltage and frequency, both of which are adjustable, to an AC<br />
motor. The inverter can automatically maintain a constant volts/Hz ratio to enhance the motor capability<br />
throughout its entire speed range.<br />
1. Only 75C CU or equivalent wires must be used for wiring.<br />
2. Inverter models with the suffix "L" (200 V class models) are suited to circuits that transmit current not<br />
exceeding 100k rms symmetrical amperes and with voltage of no more than 240 V.<br />
3. Inverter models with the suffix "H" (400 V class models) are suited to circuits that transmit current not<br />
exceeding 100k rms symmetrical amperes and with voltage of no more than 480 V.<br />
4. Suitable for use on a circuit capable of delivering not more than 100 k rms symmetrical amperes, 480 V<br />
maximum”. For models with suffix H.<br />
5. “Install device in pollution degree 2 environment”.<br />
6. “Maximum Surrounding Air Temperature 50°C”<br />
7. “CAUTION- Risk of Electric Shock- Capacitor discharge time is at least 10 min.” “Use 75C CU wire<br />
only”<br />
8. “Solid state motor overload protection is provided in each model”<br />
9. Tightening torque and wire range for field wiring terminals in the table below:<br />
