■EMC(Electro-magnetic compatibility)
The EMC of each VM-5 Series monitor is evaluated by various noise tests.
However, its characteristics may vary with on environmental conditions such as the magnitude of noise,
ambient temperature, humidity and the arrangement of equipment.
For the above reason, when operating the monitor, please observe the following CAUTION.
CAUTION
The unit should be operated by specialists or personnel who have
knowledge of it.
When a shielded cable is used, the length of the unshielded cable section
should be less than 100mm. (3.937in REF.).
For each relay used near this unit, devices related to this unit or signal
cables connecting the unit and these devices, install a surge killer.
Firmly tighten each screw used for mounting each unit. In additional,
always close the face plate for the unit, then fix it with knurled screws.
In order to prevent the system from its malfunction when the unit fails,
provide the systematic interlock function.
Do not wire input signal cables in parallel with control and power cables.
It is recommended that separated wire ducts be used for these cables.
Do not use any radio equipment near the unit.
■Noise filter
Noise transmitted through each cable may be rejected to some extent by inserting a ferrite core in the cable
(note 1).
If the cable passes through noisy surroundings, it is recommended that such a noise prevention device is used.

1. GENERAL INFORMATION VM-5P3
-1-
1-1 OVERVIEW
The VM-5P3 Phase Marker Unit combined with the VM-5H3 or VM-5W1 Instrument Rack
conducts waveform shaping of the phase marker signal and also monitors the OK alarm contact
output and abnormal internal power supply voltage for each rack. In addition, the abnormal phase
marker signal input can be detected by its setting to be able to be output as the OK signal.
• Also carefully read the instruction manuals for the VM-5H3, VM-5W1 Instrument
Racks, and for the respective transducer used.
• Test of cables using megger (insulation test):
Before conducting an insulation test of cables using a megger, always disconnect
these cables from the instrument. Also when connecting them to the instrument
after the test, always short these cables once to discharge charged electrons, then
connect them to the instrument. The instrument may be damaged if connected with
the cables charged with electrons.
• This unit is not intended for use as a single unit and, therefore, does not match the
VM-5G Single Unit Instrument Rack.
• This unit is not provided with the communication function.
