Transformerless central inverter
Prerequisites
Safety equipment available (see Chapter 2.7.2, page 19).
|
Grid voltage is within the prescribed limits (see Specifications,
|
page 87).
Before starting any work:
|
Disconnect the device and secure it against being switched back
|
on.
Ensure that the device is fully de-energised.
|
Ensure that the connections are fully de-energised.
|
Cover or shield any adjacent live components.
|
Please note:
The power source of photovoltaic systems is always active during
|
daylight.
Depending on the selected installation:
|
On a raised floor: Fitted base covers; device takes in air from below.
|
On a floor: All base covers are removed; the device takes in air from
|
the front and side, from the operating area.
Disassemble the transport rails and undo screws on the transport rails.
|
Cable leads for the connections in the operating area are provided on
|
site in the right length and size.
If there is damage, replace the cable leads.
Cable strain relief available.
|
Every central inverter has a cable mounting rail. Due to large bending
radii of the lines and cables, it can be necessary to use external cable
strain relief. The cable strain relief must only be provided with
appropriately approved components.
