The plug direction
[IN/OUT]
has to be observed. The protective device is plugged into the
relevant contact of the earthing bracket of the earthing frame at the contact leading side (PG
connection). Up to ten protective devices of the DRL 1 ... type can be tested at the same time
by means of the
EF 10 DRL
earthing frame. Test circuits 1 to 10 are switched on by means
of the test circuit selector switch. The relevant test programmes have to be performed for each
test circuit (see page 21).
2.3 If the Test button is briefly pressed, measurement is started. Finally, the measurement result
is saved automatically in the display and the test voltage is switched off. The results of all
measurements for a protective module have to be the
lower limit value (LLV [V])
and the
upper limit value (ULV [V])
(see the relevant evaluation table).
2.4 When measuring, test procedure/commissioning has to be observed (see page 30).
