WARNING: DC-powered switches are intended for installation only in a
restricted access location.

CAUTION: Before you connect power to the switch, a licensed electrician
must attach a cable lug to the grounding and power cables that you supply.
A cable with an incorrectly attached lug can damage the switch (for example,
by causing a short circuit).
To meet safety and electromagnetic interference (EMI) requirements and
