HAZARD OF ELECTRIC SHOCK
EA33/40KTLSI Grid-connected PV inverter must be installed, operated,
serviced and maintained only by trained electrically qualified persons.
Never touch live components in PV system during operating of the inverter.
Follow all safety instructions in this manual.
WARNING
WARNING! Damage to inverter
Input DC voltage must be less than 1000 V, as excessive high voltage may
result in equipment damage.
Inverter should be correctly transported, stored, assembled, installed, operated and maintained.
All operations and wiring should be performed by professional electrical or mechanical engineers so as to ensure
that all electrical installation is in accordance with relevant standard. And in order to ensure safe operation, it is
required to provide correct earthing and necessary short-circuit protection.
Ensure no electricity at DC and AC side before inspection or maintenance.
PV arrays should be covered with lightproof material when they are installed in daytime, otherwise PV arrays will
cause high voltage under sunlight.
After finishing installation or maintenance, firstly close up the AC circuit breaker, and then switch DC power. When
switching DC power, please close up the inverter DC input switch first.
