2.3  Handling the units as far as  
 

the installation site

2.3.1 General warnings and cautions

 

DANGER 

Only carry out loading operations when it has been 
ensured that all precautionary measures to protect 
personnel and materials have been taken

 

CAUTION 

The switchgear units should usually be handled in 
an upright position. Take the high centre of gravity 
into account. Tilting or overturning must be 
avoided. If necessary, single units can be carried 
horizontally, for example, because of a low 
doorway. In such cases, the unit must be supported 
over a wide area

2.3.2 Instructions
Transport units
The transport units consist of individual units or 
small groups of units. The lifting hooks are suitable 
for all UniSec units (375 mm, 500 mm, 600 mm and 
750 mm).

Handling instructions
The units must be handled in the upright position 
using a manual forklift or a forklift truck or, 
exceptionally, using special rolling tubes (at least 
four).

 

CAUTION 

The packages should be placed on a level surface.

Lifting instructions
Use the following tools for lifting:
•  Crane
•  Fork-lift truck and/or.
