4.3.- Starting the analyzer up
Before connecting the instrument to the mains, please consider following points:
5) Supply voltage: 100 V a.c. – 240 V a.c. , 50... 60 Hz.
The instrument must be energized by a supply circuit with protection earth terminal.
6) Maximum input voltage at the voltage measuring circuit:
500 V a.c. phase-neutral (CAT III)
Use always the voltage leads factory-shipped with the instrument.
7) Burden: 15 VA.
8) Operation conditions:
- Operation temperature: 0 ºC to 40 ºC.
- Operation humidity: 80% for temperatures up to 31ºC decreasing
linearly to 50% relative humidity at 40ºC.
9) Safety : Designed to meet protection category III 600V as per EN 61010.
10) Current measuring range: according to the current clamp used
Current clamps Measuring range
CP-2000-200 clamp 10 to 2000 A a.c. (scale 2000 A)
1 to 200 A a.c. (scale 200 A)
CPR-1000 clamp 5 to 1000 A a.c.
CPR-500 clamp 2,5 to 500 A a.c.
CP-100 (M1-U) clamp 0´5 to 100 A a.c.
CP-5 clamp 25 mA to 5 A a.c.
Flexible clamp Measuring range
C-FLEX 200-2000-20000 100 to 20000 A a.c. (scale 20000 A)
10 to 2000 A a.c. (scale 2000 A)
1 to 200 A a.c. (scale 200 A)
NOTE: It is always advisable to take measurements at the high range of the
scale to obtain a better accuracy.
To start measurement works with the analyzer:
11) Connect to the main with the factory-shipped cables. Also connect the protection
earth terminal to avoid possible disturbances over the analyzer.
12) Connect the voltage leads at each phase of the monitored system, as well as the
neutral when it exists.
13) Connect the Current clamps at each phase conductor. Each current phase must
coincide with its voltage phase.
14) Respect the connection modes shown at each diagram to correctly achieve
powers, PF and energies readouts.
