Safety Notes

WARNING! To avoid damage to property and equipment, injury and loss of life, adhere to applicable  electrical codes and standard wiring practices when installing and operating this product. Failure to doso could result in damage, injury and death.
WARNING! All service including inspection, installation, wiring, maintenance, troubleshooting, fuse or other user-serviceable component replacement must be performed only by properly qualified personnel. Service personnel must read this manual before proceeding with work. While service is being performed, other, unqualified personnel should not work on the unit or be allowed in the immediate vicinity.
WARNING! When in use, the power controller is connected to dangerous voltages. Do not remove the protective covers without first disconnecting and preventing power from being restored while servicing the unit.
WARNING! Electric Shock Hazard: when the power controller has been energized, after shutting off the power, wait at least one minute for internal capacitors to discharge before commencing work that brings you in to contact with power connections or internal components.
WARNING: The installation must be protected by fuses. Semiconductor fuses are classified for UL®  as supplementary protection for semiconductor devices. They are not approved for branch circuit protection.
NOTE! The nominal current is specified for ambient temperatures at or below 50°C. Ensure the application design allows for adequate cooling of each power controller. The power controller must be mounted vertically. The cooling design must prevent air heated by one power controller from causing power controllers mounted above to exceed the ambient operating temperature limit. When power controllers are mounted side by side allow a minimum spacing of 15mm between them.
NOTE! Use only copper cables and wires rated for use at 75°C or greater.
