Wiring must conform to National Electric Code
(NEC) safety standards, as well as locally applicable codes. Failure to do so could result in death or
personal injury.
Wiring examples show L2 in 240VÅ (ac) or 480Å
(ac) configuration. In 120VÅ (ac) or 277VÅ (ac)
applications, L2 is neutral and must not be fused
or switched. Failure to follow this guideline could
result in death or personal injury.
Installation and service by qualified personnel
only. Failure to do so could result in death or
personal injury.
Hot surface, do not touch heat sink. Failure to follow this guideline could result in personal injury.
