Installation 3. Wiring
Do not connect terminal and RJ-45 connector with live wires.
Do not
It may cause electric shock, burns, device burn out, or fire.
It is recommended that a protection fuse be used for VT and the auxiliary power source.
Connect the CT secondary side signal correctly to the terminal for CT connection.
If the CT is not connected properly or if the secondary side of the CT is open, it may result
in high voltage on the secondary side of the CT, the insulation of the secondary winding
wire may be damaged, and burnout may be caused.
Connect the VT secondary side signal correctly to the terminal for VT connection.
If the VT is not connected properly or if the secondary side of the VT shorts, over current
may flow to the secondary side of the VT, which can burn out the secondary winding wire.
If the secondary winding wire burns out, it can damage the insulation of the primary
winding wire, resulting in a short between phases.
Electrical wires must be properly tightened to the connection terminal.
Otherwise, heat and measurement errors may be caused.
CAUTION
When the L side of CT circuit is common wire, it is necessary to short-circuit "C1","C2",
and "C3" terminal of this device.
Make sure that the electrical wires have the proper rating for current and voltage.
If inappropriate electrical wires are used, fire may be caused.
If the terminal wiring is pulled with a strong force, the input and output portion may detach.
(Tensile load: 39.2N or less)
If a pressure test is given to a high-pressure device, a ground must be used in order to
avoid damaging this measurement instrument. If a high voltage of AC2000V is applied for
over one minute to the measurement instrument, damage may occur.
Do not connect to Non-Connection (NC) terminals for the purpose of relay etc.
Use the proper voltage for the auxiliary power source terminal.
If an improper voltage is used, the instrument may be damaged or fire may be caused.
Do not work with live wires
insert and remove SD CRAD with live wires.
Do not open the secondary side of the CT circuit
Do not short the secondary side of the VT circuit
Make sure connections to the connection terminals are tight
Do not forget wiring of "C
Do not use improper electrical wires
Do not pull the connection wires with force
Do not apply an abnormal voltage.
Do not connect to Non-Connection (NC) terminal.
Use the proper voltage for the auxiliary power source.
