4.5 Intermediate storage
Optimum intermediate storage, where this is
necessary, without any negative consequences
depends on compliance with a number of minimum
conditions for the panels and assembly materials.
1. Panels with basic packing or without packing:
•
A dry well-ventilated store room with a climate
in accordance with IEC 62271-1
•
The room temperature must not fall below -5 °C
•
There must not be any other negative
environmental influences
•
Store the panels upright
•
Do not stack panels
•
Panels with basic packing
•
Open the packing, at least partially
•
Panels without packing:
-
Loosely cover with protective sheeting
-
Ensure that there is sufficient air circulation
•
Check regularly for any condensation until
installation is started
2. Panels with seaworthy or similar packing with
internal protective sheeting:
•
Store the transport units
•
Protected from the weather
•
In a dry place
•
Safe from any damage
•
Check the packing for damage
•
Check the drying agent (also see section 4.2):
-
On arrival of the consignment
-
Subsequently at regular intervals
•
When the maximum storage period, starting
from the date of packing, has been exceeded:
-
The protective function of the packing can
no longer be guaranteed
-
Take suitable action if intermediate storage
is to continue
Warning
Do not walk on the roof of the panels
(rupture points in pressure relief devices!).
The pressure relief devices and/or Ith
Limiters could be damaged.
4.6 Handling
4.6.1 Switchgear
The switchgear sections are usually fixed to
wooden pallets. Handling should be carried out
by means of bridge or mobile cranes. Otherwise,
use rollers or fork lift trucks.
Weights and dimensions of each section are listed
in the shipping documents and in the plant
drawings.
4.6.1.1 Handling with bridge crane or mobile
crane and unpacking
Handling the switchgear in the wood packing.
The switchgear must be lifted by means of a crane

Weight and lifting opening angle must be taken
into account when choosing the circular slings.
