3. EXTERNAL WIRING
WARNING
●
To avoid the risk of an electric shock, turn off the
power supply and use a tester or similar device to
ensure that no power is supplied to a cable to be
connected, before carrying out wiring work.
●
Do not operate the product in the presence of
flammable or explosive gases or vapors. To do so is
highly dangerous.
●
Use of the product ignoring the specifications may
cause overheating or damage. Before turning on
the power, ensure the following:
•
Power supply voltage and input signal value
applied to the product should meet the required
specifications.
•
The external wiring to the terminals and wiring to
ground are as specifications.
Note:When power of VJP8 is turned on/off, one pulse may be counted by the
pulse input device which connects to the VJP8.
Wiring should be connected to the terminals on the socket
of the product. The terminals for external connections are of
M3 screws. Use crimp-on terminal lugs for connections to the
terminals.
•
Recommended cables: A nominal cross-sectional area of
0.5 mm
2
or thicker for signal cables, and that of 1.25 mm
2
or
thicker for power cables.

CAUTION
●
Do not use output-2 for the isolated single-output
type.
●
The power line and input/output signal lines should
be installed away from noise-generating sources.
Other wise accuracy cannot be guaranteed.
●
Make sure to earth ground the ground terminal
through minimum resistance. The length and
thickness of the grounding cable should be as
short and thick as possible. Directly connect the
lead from the ground terminal (terminal no. 8) of
the product to the ground. Do not carry out daisy-
chained inter-ground terminal wiring.
●
The product is sensitive to static electricity;
exercise care in operating it. Before you operate
the product, touch a nearby metal part to discharge
static electricity.
●
If the ambient temperature is 50 °C or more, please
use the cable that the rated temperature is 70 °C or
more.
