Checking the auxiliary
switch of the ready-for-
service indicator
802-9074.9 • INSTALLATION AND OPERATING INSTRUCTIONS • NXPLUS C Wind • Revision 05
You may only start installing the transport units when
• all transport damages have been repaired
• the base frame has been levelled (1 mm/m), see DIN 43661
• the SF
gas filling in the vessels has been checked (see page 67, "Checking the ready-for-
6
service indicator").
• the accessories and the required material are complete (see page 59, "Before installation").
Place the first (i.e. rearmost) transport unit as exactly as possible on its final location and
place the second one close to it, keeping a small distance so that the units can still be
aligned before bolting together.
Remove packing and transport materials from the place of installation.
Remove any dirt occurred during transport, as extreme cleanliness is required during
installation.
Now the transport units are in the correct order for assembly.

Checking the ready-for-service indicator

The panels are filled at a pressure of 1500 hPa. Before starting installation, check the ready-
for-service indicator. It is located on the right side of the control board.

Read the ready-for-service indicators.
If the pointers are in the green area, the gas filling is in order.
r
If the pointer is in the red area: Check the auxiliary switch of the ready-for-service indicator.
During transport, the auxiliary switch of the ready-for-service indicator can latch tight in the
red area due to extreme vibrations.
To put the ready-for-service indicator into operation again, the plastic part fixed at the
auxiliary switch must be brought to the initial position again by hand.
Remove the front plate of the switchgear. Push the plastic part
downwards with the index finger until the ready-for-service indicator jumps back to the
green area. When pushing the plastic part at the auxiliary switch down from the latched
position, you must overcome a mechanical resistance. In order to avoid damaging the
plastic part, it must be supported with one finger when being pushed down.
Then, the pointer must return to the green area automatically. If not, please stop the
r
installation and contact the regional Siemens representative.
