The responsibilities of the consignee when the switchgear arrives at site include, but are not limited
to, the following:
• Checking the consignment for completeness and lack of any damage (e.g. also for moisture and its
detrimental effects). In case of doubt, the packing must be opened and then properly resealed,
putting in new drying agent bags, when intermediate storage is necessary;
• If any quantities are short, or defects or transport damage are noted, these must be:
- documented on the respective shipping document;
- notified to the relevant carrier or forwarding agent immediately in accordance with the relative
liability regulations.
Note
Always take photographs to document any major damage.
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 60694;
• 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 by damaged.

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 and circular slings 1 (figure 30). The slings must
be inserted according to the lifting symbols marked on the crate.
Weight and lifting opening angle must be taken into account when choosing the circular slings.
