11.7 Testing Extension Cables for VDE 0701, Part 1, and VDE 0702

(option: EL1 adapter) 

Extension Cables up to 5 m Long

Protective conductor resistance between the earthing contact at the 
mains plug and all exposed metal parts may not exceed 0.3

Ω 

for safety 

class I devices. This value may not exceed 1

Ω

 for permanently 

connected data processing systems (DIN VDE 0701, part 240).

Extension and Connector Cables Longer than 5 m

Per DIN VDE 0702, an additional cable resistance of 0.1

Ω

, however, not 

more than 1

Ω

, is allowable as of a length of 5 m for each additional 

7.5 m.

Resistance testing for cables longer than 5 m is thus advisable (see also 
limit values on page 17).

Note

☞

The EL1 accessory adapter is required for testing for short-
circuiting and interruption of single-phase extension cables.

Connecting the Extension Cable or the Multiple Outlet

Note

☞

The keys in the adapter’s handle have no function.

Performing the Test

➭

Connect the extension cable to the EL1 adapter as shown in the figure 
above.

➭

Select the “Ext. Cable” test from the initial menu with the cursor and 
acknowledge with the 

 

key: Ext. Cable 

x

 WITH EL1.

➭

Select “Start Test” with the 

 

key.

➭

Start the measurement sequence with the 

 

key.

➭

First perform and acknowledge visual inspection of the extension cable.

➭

Enter the length of the cable with the 

 

and 

 

keys. Acknowledge with 

the

 

 

key.
