3.7 Power Connection
CAUTION
Risk of electric shock and fire caused by high leakage current!
Before connecting the device to the supply circuit, establish a ground
connection by means of the labeled ground stud!
The power connection has to be connected with a 5 wire cable. For security reasons, protective
conductor PE must be connected in any case.
The power supply line must be equipped with an appropriate line protection. More information re-
garding the power connection you will find in Chapter 7 the Technical Data under 7.1
.
Reducing factors must be taken into account if circuit breakers are connected in series. Always
observe the following standards:
DIN VDE 0298-4 Types of cable placement and current-carrying capacity
DIN VDE 0100; Part 430 Protective measures: protection of cable and cords against
over current
DIN VDE 0100; Part 410 Protective measures: protection against electric shock
Also observe the following requirements specified by the local network operator:
• Pertinent technical and special rules and regulations
• The installation approval must be submitted.
CAUTION
Before connecting the LSPV inverter to the AC network, isolate the power
connection, verify that the system is de-energized, and protect the circuit
breaker against reactivation.
• Check the line voltage, which may not exceed 265 V (phase against neutral conductor).
If the line voltage is higher than 265 V, contact your local network operator.
• Apply the power cable to the supplied connector as illustrated, connect the power cable
to the LSPV inverter and fasten the connector.
