Precautions Concerning Compliance with UL and cUL Standards
(Standards to be met: UL508C and CSA C22.2 No. 14-05)
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 SJ700B series except for
SJ700B-110L,SJ700B-150L;SJ700B-075H,SJ700B-110H and SJ700B-150H.
2. “Use 75 C CU wire only” or equivalent. For models SJ700B series except for
SJ700B-110L,SJ700B-150L;SJ700B-075H,SJ700B-110H and SJ700B-150H.
3. “Suitable for use on a circuit capable of delivering not more than 100 k rms symmetrical amperes,
240 V maximum”. For models with suffix L.
4. “Suitable for use on a circuit capable of delivering not more than 100 k rms symmetrical amperes,
480 V maximum”. For models with suffix H.
5. “Install device in pollution degree 2 environment” or equivalent.
6. “Maximum Surrounding Air Temperature 45 or 50°C” or equivalent.
7. “CAUTION- Risk of Electric Shock- Capacitor discharge time is at least 10 min.” or equivalent.
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.” or equivalent.
9. “Solid state motor overload protection is provided in each model” or equivalent.
10. Tightening torque and wire range for field wiring terminals are marked adjacent to the terminal or on
the wiring diagram or instruction manual.
