Maintenance

Testing the 3-Phase Connection

➭

Turn the top

rotary selector switch

(S1) at

the test adapter to the Status C position

(system state: vehicle ready for

charging).

➭ Turn the bottom rotary selector switch

(S2) to each switch position*.

With the exclusion of the exceptions specified

in the following table, a protective conductor

resistance R

of less than 2



is permissible.

This is due to the design of the test adapter.

The PE connection between OUT1 and

OUT2 must also be tested (< 2



11.2.2 Testing Insulation Resistance

Testing is conducted in the respective switch

positions for Status B, C or E and in the

green ON position for 3-phase testing at

short-circuited L-N or L1-L2-L3-N contacts

(for earthing contact and CEE respectively)

• at mains connections N1 and N2

• at the power supply end of the test

object, ICCB-IN1

• at the output end of the test object, ICCB-

OUT1

in each case against PE.

The usual limit values apply.

11.2.3 Touch Current Measurement

Touch current measurement is conducted at

the screw connections of the IN sockets

(IN2, IN3 and IN4) with the standard limit val-

ues (I

<0,5mA).

11.3 Fuse Replacement

The test adapter may only be operated with

fuses in flawless condition. Damaged or

defective fuses must be replaced immedi-

ately.

All fuses for neutral and phase conductors

are accessible from the outside.

Attention!

Life endangering due to electric

shock!

The test adapter is operated with

electric power. Therefore there is a

general risk of electric shock which

can be fatal or cause severe injury.

– The test adapter must be voltage-

free both before and during changing

the fuse. Switch the test adapter off

and disconnect it from the mains

power supply.

– The test adapter may not be con-

nected to a measuring circuit before

and during cleaning.

Attention!

Only install fuses of a type that con-

forms to the details specified in the

Technical Data, see page 9.

No other fuses may not be used in

the test instrument.
