WARNING
ELECTRIC SHOCK HAZARD
Do not remove cover. No user serviceable parts inside.
Refer servicing to qualified service personnel.
This is a transformerless device. The DC conductors of this photovoltaic system are
normally ungrounded but will become intermittently grounded without indication
when the inverter measures the PV array isolation.
When the photovoltaic array is exposed to light, it supplies a DC voltage to this
equipment. Disconnect AC and DC individually and wait 5 minutes before servicing.
Hazardous voltage remains for 5 minutes after disconnecting main power supply.
Do not touch terminals. All terminals may be energized in the open position.
Hot surfaces – To reduce the risk of burns, do not touch.
Contains FCC ID: SVF-KP20 Contains IC: 9440A-KP20
This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
