DANGER
RISK OF ELECTRIC SHOCK OR ELECTRIC
ENERGY-HIGH CURRENT LEVELS
Dangerous electric charge may be stored
in capacitor and associated circuitry.
Test before touching.
E
DANGER
RISK OF ELECTRIC SHOCK
Capacitors stay charged after power has
been shut off.
Accidental contact with live parts can
cause personal injury and death.
Turn off and lock out all power sources.
Wait at least five (5) minutes for power to
dissipate then check voltage before
servicing

Grounding Electrode
Terminal
H
The output ac circuit is considered as a
separately derived source. If local codes
require grounding of this circuit, use
terminal (identify terminal) for bonding
this circuit to the enclosure. Ground the
enclosure to a suitable grounding
electrode in accordance with local code
requirements.
