1. UL standard
UL standard is the general standard of motor control devices in the United
States. Safety standard for devices, equipments, materials are established to
protect human life and property from fire, electric shock, and other accidents.
The FR-BU2 is considered as part of power converter and subject to
UL508C(Power Conversion Equipment) .
2. Necessity of UL qualification
Laws in the U.S.A are divided into federal laws and municipal laws of states
and cities. The fedederal government stipulates minimum regulations only
and local governments set specific rules. UL standard is not therefore
enforced by a federal law. However, some local governemnts specify the
necessity of product safety certification by the UL or other testing agency
and even some local governments without regulations require that products
should satisfy minimum standard which meets "safety products" set by a
federal law.
