Maintenance

11 Maintenance

11.1 Cleaning of Housing

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 cleaning.

Switch the test adapter off and dis-

connect it from the mains power

supply.

– The test adapter may not be con-

nected to a measuring circuit before

and during cleaning.

– Never immerse the test adapter in

water or other liquids.

– Never touch the test adapter to

with wet or moist hands.

No special maintenance is required. Keep

outside surfaces clean and dry.

Attention!

Unsuitable cleaning agents such as

aggressive or abrasive cleansers re-

sult in damage to the test adapter.

– Use a cloth for cleaning which has

been slightly dampened with water.

– Avoid the use of cleansers, abra-

sives or solvents.

11.2 Technical Safety Inspections

Testing per DGUV Regulation 3

Subject your test adapter to technical safety

inspections at regular intervals.

The test adapter is designed in accordance

with IEC 61010 as a protection category I

and II test instrument.

Testing of the protective conductor, insula-

tion resistance and touch current is

described in the following subsections.

11.2.1 Testing of Protective Conductor Resis-

tance R

Test Adapter Contacting,

Single-Phase (230 V)

Protective conductor resistance is tested

between the PE contact at the mains plug

(inlet plug N1) and PE contacts ICCB IN1

through IN4.

Testing the Single-Phase Connection

➭

Turn the top rotary selector switch

(S1) at

the test adapter to the Status C position

(system state: vehicle ready for

charging).

With the exclusion of the exceptions speci-

fied in the following table, a protective con-

ductor resistance R

of less than 2  is

permissible. This is due to the design of the

test adapter.

Test Adapter Contacting, 3-Phase (400 V)

Protective conductor resistance is tested

between the PE contact at mains connec-

tion N2 and the PE contact at ICCB-IN1

(parallel to IN2, IN3 and IN4).
