On Wiring:
Connections to the instrument should be made to the terminal
block. For assignment of the terminals, refer to section 6. The
recommended screwing torque is 0.8 to 1.0 Nm.
For lead wires, use a highly flexible stranded conductor. The
recommended nominal cross-section of the lead wire conductor
is 0.5 to 2.0 mm
2
.
The connection of the lead wire to the terminal block should be
made with the insulated crimp terminal attached to the end of the
wire. Without the insulation, short circuit or electric shock may
occur. The recommended thickness of the crimp terminal is 0.7
to 1.0 mm.
Note that only up to two (2) crimp terminals can be connected to
one (1) terminal screw. In this case, the thickness of the crimp
terminal should be not greater than 0.8 mm.

To Avoid Erroneous Measurements:
Avoid wiring the signal lines in the vicinity of equipment
generating magnetic fields or electromagnetic waves, such as
electric motors and large-scale transformers. If inevitable,
anti-noise measures such as employment of shielded wires are
indispensable.
At least 30 minutes of warm-up is required prior to operation.
Any sensor or equipment to be connected to the instrument
should be selected in consideration of the input/output
impedance of the same. (For detailed specifications, refer to
section 4 or the relevant product specification sheet that can be
downloaded from our website at https://www.mtt.co.jp.)
Special Notes for CE Marking:
The instrument is designed and manufactured to conform to the
following EMC Directive:
EMC Directive (2014/30/EU)
- Standard conformity: EN61326-1:2013 Class A
The instrument must be installed in a control panel.
When the instrument is installed in a control panel, the measures
to be taken for CE marking conformity may vary with the type of
devices connected, wiring to the instrument or structure of the
control panel. Therefore, you should check that the control panel
as an overall system conforms to the CE marking regulations.
