Pv String Protection; Esd Protection; Grounding Requirements - Soleil SRT 75K User Manual

1.1.2 PV String Protection

When install PV string in daytime, it necessary to cover the PV string by light-proof material, or the
PV string will generate high voltage under sunlight. If touching PV string accidently, it may cause
electric shock or human injury!
Dangerous voltage between the positive and negative of PV string is present!
When installing the device, make sure that the connection between inverter and PV string has been
disconnected completely. Set warning mark in the disconnected position to avoid reconnecting.

1.1.3 ESD Protection

To prevent damaging of sensitive components (such as circuit board) due to human electrostatic
charge, make sure that you wear anti-static wrist strap before touching sensitive components, and that
the other end is well grounded.

1.1.4 Grounding Requirements

High leakage risk! The inverter must be grounded before wiring. The grounding terminal must be
connected to ground, or there will be the risk of electric shock when touching the inverter.
When installing, the inverter must be grounded first.
When dismantling, the grounding wire must be removed at last.
Don't damage the grounding conductor.
The inverter must be connected to protection grounding permanently.
Before operation, check the electrical connection to ensure the inverter is grounded reliably.
