Terminal block connection diagram
Tighten the terminal screws (M4 x 10) to a torque
of approximately 1.5 Nm (15 kgf·cm) <11ft-lb> so
that the wires will not loosen.
After connection, fasten the cover until it does
not turn.
When using an external Field indicator
For direct connection to an external
fi
eld indi-
cator, connect the “+” and “–” sides of the
fi
eld
indicator to CK+ and CK– of the transmitter as
shown below.
Use an external
fi
eld indicator with internal resis-
tance of 12
Ω
or less.
7.1 Wiring procedure :
Sealing of conduit connection
Use sealing tape, if using metal pipe screw coupling or rubber gasket and fastening gland in
the case of cable to ensure airtightness of the connection box.
1. If the connection box is located above the transmitter when using a
protective tube for the wiring, then moisture may enter the protective
tube and have an adverse effect on the transmitter. So maintaining
airtightness of the connection box is an important practice.
2. The thread of conduit tube should meet the selected size and a seal
fi
xture should be used.
