45 to 65 Hz
On request:
500 V a.c. phase-to-neutral / 866 V a.c. phase-to-phase
110 V a.c. phase-to-neutral / 190 V a.c. phase-to-phase
c.- Maximum allowable current : Current Transformer of In / 5 A a.c.
d.- Operation conditions :
- Operation temperature range: -10 to +50 ºC
- Humidity : 5 to 95 % R.H. non-condensing
e.- Safety : Designed to meet protection class III- 300 V a.c. as (EN 61010).
Mounting:
Instrument is to be mounted on panel (cut-out 92
+0.8
x 92
+0.8
mm, as per DIN
43 700). 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 a circuit breaker or any equivalent element to connect (ON) or
disconnect (OFF) 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
.
