16.1.1 Extension cable
 Only use approved extension cables, see chapter Safety.
 Find the necessary stranded conductor cross-section of the extension cable in the following table:
Example: An IRflex58/120/5 is to be mounted onto an FUflex4/120 and this unit extended with an
extension cable measuring 20 m. According to the table, given a supply voltage of 120 V 1~, the
extension cable must have a stranded conductor cross-section of at least 2.5 mm².
WARNING
Electrical voltage.
Injury from electric shock.
 Check power cable and extension cable for damage.
 Only use extension cables whose grounded conductor is connected to the plug and
coupling (only for machines of class rating I, see chapter Technical data).
NOTICE
Find the model designation and voltage of the machine on the nameplate or using the item
no. in the chapter Technical data.
