WARNING!
The inverter cover must be opened only after switching the inverter ON/OFF/P
switch located at the bottom of the inverter to OFF. This disables the DC voltage
inside the inverter. Wait five minutes before opening the cover. Otherwise, there
is a risk of electric shock from energy stored in the capacitors.
WARNING!
Before operating the inverter, ensure that the inverter AC power cable and wall
outlet are grounded properly. This product must be connected to a grounded,
metal, permanent wiring system, or an equipment-grounding conductor must
be run with the circuit conductors and connected to the equipment grounding
terminal or lead on the product.
WARNING!
Opening the inverter and repairing or testing under power must be performed
only by qualified service personnel familiar with this inverter.
WARNING!
The inverter input and output circuits are isolated from the enclosure. This
system does not include an isolation transformer and should be installed with
an ungrounded PV array in accordance with the requirements of NEC Articles
690.35 and 690.43 National Electric Code, ANSI/NFPA 70, 2011 (and Canadian
Electrical Code, Part I, for installations in Canada).
Equipment grounding is the responsibility of the installer and must be
performed in accordance with all applicable Local and National Codes.
WARNING!
Do not touch the PV panels or any rail system connected when the inverter
switch is ON, unless grounded.
WARNING!
SafeDC complies with IEC60947-3 when installing the system with a worst case
SafeDC voltage (under fault conditions) < 120V.
The worst case voltage is defined as: Voc,max+ (String Length-1)*1V, where:
Voc,max = Maximum Voc (at lowest temperature) of the PV modules in the
string (for a string with multiple modules, use the max value)
String Length = number of power optimizers in the string
