(b) Current input of 5 A a.c. ( maximum current of 6 A a.c. ).
(Overload current of 100 A for half a second).
(c) Frequency : 45 ... 65 Hz
(d) Instrument burden : 0,5 VA
(e) Operation conditions :
- Operating temperature : 0º C / +50º C
- Humidity : 25 to 75 % R.H. noncondensing
(f) Safety : Designed to meet protection class II as per EN 61010.
Mounting:
Instrument is to be mounted onto a DIN rail.
All connections keep inside the cabinet.
Note that with the instrument powered on, the terminals could be dangerous to
touching and cover opening actions or elements removal may allow accessing
dangerous parts. Therefore, the instrument must not be used until this is completely
installed.
The instrument must be connected to a power supply circuit protected with gl type
(IEC 269 ) or M type fuses rated between 0.5 and 2 A. This circuit should be
provided with an automatic switch ( ON / OFF ) or any equivalent element to
disconnect the instrument from the power supply network. The supply and measuring
voltage circuits will be both connected through a wire with a minimum cross-section
of 1 mm
2
. The line of the current transformer secondary will have a minimum cross-
section of 2,5 mm
2
.
