·
CAUTION
For safety's sake and to protect the functionality of the product, don't draw out its body from the case. If it needs to be drawn out for
replacement or repair, contact our sales agent.
c
Cut a hole for mounting the controller in the panel by referring to the cutout drawing in Section 3-3.
d
The panel thickness should be 1.0 - 4.0 mm.
e
As the instrument is provided with pawls for fixing, just press it firmly from the front of the panel. The case is fixed to the panel by
means of the pawls.
f
The FP93 is designed as a panel-mounting model. Never use it without mounting on the panel.

3-4. Wiring
In wiring operation, close attention should be paid to the following:
·
CAUTION
z
Make sure to disconnect this instrument from any power source during wiring operation to prevent an electric shock.
z
Be certain that the protective conductor terminal (
Ã
) is properly grounded. Otherwise, an electric shock may result.
z
To prevent an electric shock, don't touch wired terminals and other charged elements while they are being energized.
c
In wiring operation, follow the terminal layout shown in Section 3-5 and the terminal arrangement in Section 3-6 and make sure to carry
out the correct wiring.
d
Use press-fit terminal which fits an M3.5 screw and has a width of 7 mm or less.
e
In case of thermocouple input, use a compensating cable compatible with the selected type of thermocouple.
f
In the case of R.T.D. input, the resistance of a single lead wire must be 5
or less and the three wires must have the same resistance.
g
The input signal wire must not be accommodated with a high-voltage power cable in the same conduit or duct.
h
Shield wiring (single point grounding) is effective against static induction noise.
i
Twisting the input wires at short and equal intervals is effective against electromagnetic induction noise.
j
In wiring for power supply, use a wire or cable whose performance is equal to or higher than the 600V vinyl insulated wire having a
sectional area of 1 mm
2
or larger.
k
The wire for grounding must have a sectional area of 2 mm
2
or larger and must be grounded at a grounding resistance of 100
or less.
l
Clamp the screws of terminals firmly. Clamping torque: 1.0 N • m (10kgf • cm)
ջ
If the instrument appears to be easily affected by power supply noise, use a noise filter to prevent malfunctioning.
ռ
Mount the noise filter on the grounded panel and make wire connection between the noise filter output and the power line terminals of
the controller as short as possible.
