Connection of the Transmitter to the Terminal Box
Connect the Transmitter to the Terminal Box in accordancewith the following procedure.
Measure of strip cables (Fig. 1)
1. Strip outer sheathes of cable.
2. Strip insulations of cores.
Fastening position of cable (Fig. 2)
Make sure that outer sheath of cable is positioned insideof the Terminal Box properly in tightening cable.

CoresInsulations

10mm50mm（ﬁg.1）
Body

Mounting of Cable <ﬁg. 3>
Put a cap and sealing ring on cable, then insert the cableto the body.
Put a cap on the Cable Gland and tighten it with aspanner. ( Spanner caliber : 17mm )Applicable cable diameter : 5.0...8.0mm
Tightening torque : 6Nm
The cap can be shut up tightly to the body.
Replace the sealing rings of Cable Glands when you
change Transmitter in maintenance to avoid decline of its
watertight quality.
Sealing ring Code : 991995008
Type number : KBC-F2/E150P8
Connecting to Terminal block
Press the button with slotted screw driver (width of edge : 2.6mm)
and connect the core.
Insert core to reach terminal suﬃciently.
( If a core was inserted insuﬃciently, core may come out or cause shortwith adjoining cable. If a core was inserted exceedingly, the core cannot
be connected suﬃciently because of terminal catching insulations.)

InstallFix the Terminal Box with three M5 Allen screws(length : longer than 20mm).
Put on the lid on the Terminal Box horizontally and screw in the lid carefuly or damaged thread of the lid,then insert and fasten it tightly.

Unused connectors should be protected by blank plugs which supplied with box.

In using angle connectors, use a connector which a projection is positioned
indicated in the right ﬁgure.
If you use diﬀerent type connectors, connectors interfere each other and otherconnectors cannot connect into the contacts.

*Use this type connector.
