Step 2
Select
nominal differential current I
∆
N
as follows:
q
Press the
SELECT
key, last set nominal differential current starts to blink.
q
Select appropriate value using the
▲
and
▼
keys. The following values are
available: 10mA, 30mA, 100mA, 300mA, 500mA or 1000mA. The value ×5 is
not available, if nominal current I
∆
N=1000mA.
Step 3

SELECT
key after setting nominal differential current, last set
multiplier starts to blink.
q
Select appropriate value by using the
▲
and
▼
keys. The following values are
available to be selected: ×1/2, ×1, ×2, ×5. The value ×5 is not available, if
