2.5.1.5 CABINET
To assist customers in simplifying the wiring of current transformers (CTs) when using Sinexcel cabinets,
Sinexcel has introduced CT terminal blocks.
CAUTION
An open circuit of CT secondary side when there is load current exists
is forbidden.
NOTICE
Sinexcel module is support 3P3W and 3P4W at the same time,
according to circuit calculation, for 3P3W system only needs two CTs
connect at L1 and L3; For 3P4W system needs three CTs connect at
L1, L2 and L3.
NOTICE
Once external CT is installed at the power distribution, CT secondary
side terminal must be short-circuited and disconnected after CT
secondary side cable is connected to the corresponding terminal.
Users need to configure this short circuit device by themselves when
connecting CT. Make sure that all secondary side GND ends of
three-phase L1re short-circuited and connected to SVG PE line before
CT is connected to the system, so as to ensure the safety of operator.
NOTICE
The following procedures need to be taken when the device needs
maintenance:
1) Before drawing out the module, push gliding slab 3, 8 and 13 of CT
terminal to "connecting" state;
2) After installing the new module, push gliding slab 3, 8 and 13 of CT
terminal to "breaking" state.
