
Lethal voltages 1000 V DC. Keep out.
 No user serviceable parts inside. Only trained
service personnel are allowed access.

Both AC and DC voltage sources are
terminated inside this equipment. Each circuit
must be disconnected before servicing.
 When the photovoltaic array is exposed to light,
it supplies DC voltage to this equipment.
 The DC conductors of this photovoltaic system
are ungrounded and may be energized.
 The DC conductors of this photovoltaic system
are normally ungrounded but will become
intermittently grounded without indication
when the SUN2000 measures the PV array
isolation.
Do not touch a running SUN2000 because it
generates high temperatures on the shell.
