4.5: Wiring the Monitored Inputs - Currents
The cables to the current inputs shall be rated for a minimum of 600 V AC and 10 A
(14 AWG copper cable, cross sectional area of 2.08mm
2
).
Mount the current transformers (CTs) as close as possible to the MP200 unit’s meters.
The following table illustrates the maximum recommended distances for various CT
sizes, assuming the connection is via 14 AWG copper cable.
WARNING! DO NOT leave the secondary of the CT open
when primary current is flowing.
This may cause high volt-
age, which will overheat the CT. If the CT is not connected, pro-
vide a shorting block on the secondary of the CT.
AVERTISSEMENT! NE PAS laisser le transformateur de courant secondaire
ouvert lorsque le courant primaire est fluent.
Cela peut provoquer une haute ten-
sion qui surchauffera le transformateur de courant. Si ce dernier n'est pas branché,
fournir un court-circuit sur le transformateur de courant secondaire.
