■Safe use
WARNING
Make sure to ground.
May cause electric shock or malfunction.
Make sure to turn the power off before any wiring work.
Will cause electric shock.
CAUTION
Make sure that the power supply connected to the power supply input
terminals has the specified voltage and frequency.
Will cause damage and malfunction of the instrument.
A printed circuit board and electronic products may receive damage with
the static electricity of a human body.
Touch the metal part once and discharge your static electricity before
dealing with it.
Will cause damage and malfunction of the instrument.
Do not touch parts and soldered surfaces of the instrument rack.
Will cause damage and malfunction of the instrument.
The instrument rack is a precision instrument.
Take care not to expose it to excessive shock or vibration.
Do not change the parameter settings during operation.
May cause unexpected alarm output.
Do not measure insulation resistance and dielectric strength other than
those at places specified.
Will cause damage to the instrument.
Do not touch the surface of the instrument rack in the case of the high
environment temperature use, since the surface temperature of the rack
may be higher than the environment temperature by 10 to 20°C.
Do not remodel this monitor unit without permission.
Otherwise the guarantee can not be made.

■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.
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 in 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.

series monitor (except VM-5P Communication / Phase Marker Unit), 4-opint relay, SPDT(DAN.1,
DAN.2, ALE.1, ALE.2) and OK relay.
FEATURES
• Conforms to API St’d 670.
• Contact output (Danger / Alert alarm).
• Contact output (Input abnormal alarm).
• Can use variable voltage and frequency (85 to 264VAC / 48 to 64Hz) as power supply.
• Single unit independent type
• Carefully read both this manual and the manual for the VM-5 Series monitor unit to
be mounted in this rack.
• For INTERCONNECTION and MAINTENANCE proceed as described in the
instruction manuals for the VM-5 Monitor Unit used in combination with this
instrument rack.
•If megger test is made on the signal cable between transducer and monitor,
disconnect the cable from transducer and monitor.
Be sure to discharge the charged electric load before connecting the cable to the
transducer and monitor.
If this caution is not adhered to, the transducer and monitor could be damaged.

Note) Ventilation holes are drilled through the top, bottom and side faces of the instrument rack for natural
cooling. When mounting the instrument rack within the panel, do not close these ventilation holes. I
f
closed, the temperature in the rack may rise to shorten the service life of electronic parts used.
Do not place anything which interrupts ventilation within 200 mm from top and bottom faces of th
e
instrument rack.
Do not place the apparatus which generates heat under the instrument rack.
Be careful when installing the instrument rack in a bad-ventilated closed box (instrument panel).
It may cause shortening the life time of electronic parts because of marked rising in temperature of th
e
instrument rack in a bad-ventilated closed box which keeps the heat in.
Cool down inside the box with a cooling fan or the like.
Especially when installing in a small closed box, use the forced-air cooling apparatus like an electronic ai
r

4-1 POWER SUPPLY WIRING
•Beware of electric shock from high-voltage parts.
• When using a DC power source, make especially sure not to reverse the polarities
as this will cause serious damage.
• Make sure to confirm that the power supply voltage matches that of the equipment.
• Use cables with AWG No.14 to No.18 gage (0.75 - 2mm2) stranded conductors for
wiring of the power supply input terminals.
•Make sure to ground the GND terminal.
•Make sure to ground the GND terminal.

• Beware of electric shock from high-voltage parts.
• Sequence function
Short between the SEQ and COM terminals to activate the sequence function.
• Reset function
Short between the RES and COM terminals to release any alarm under hold.
• Power sequence function sequence
Short between the P-S (power sequence) and COM terminals to cut off the
secondary (internal) power supply.
• Filter sequence function.
Short between the FLT and COM terminals to activate the seismic filter function.
• It is necessary to keep short circuit of the terminals for more than one (1) second to
operate these functions.
• Power sequence function should be applied only for short time (less than one (1)
minute) and emergency use such as the case of pulling out and inserting the monitor
unit.
If this function is used for long time over one (1) minute, monitor damage will result.

• Make sure to insulate the buffer output against earth.
If not insulated, a 2-point earth system results, which may cause noise interference.
• In the case that VM-5G is used with VM-5C eccentricity monitor unit, the connection
wiring of the recorder output and buffer output shall be as the following table.
And in the case that VM-5G is used with the monitor unit with the one (1) recorder
output, the recorder output shall be output from the CH1 recorder output terminal.

• Ventilation holes are drilled through the top, bottom and side faces of the instrument
rack for natural cooling. When mounting the instrument rack within the panel, do not
close these ventilation holes. If closed, the temperature in the rack may rise to
shorten the service life of electronic parts used.
Do not place anything which interrupts ventilation within 200 mm from top and
bottom faces of the instrument rack.
Do not place the apparatus which generates heat under the instrument rack.
• Be careful when installing the instrument rack in a bad-ventilated closed box
(instrument panel).
It may cause shortening the life time of electronic parts because of marked rising in
temperature of the instrument rack in a bad-ventilated closed box which keeps the
heat in.
Cool down inside the box with a cooling fan or the like.
Especially when installing in a small closed box, use the forced-air cooling apparatus
like an electronic air conditioner.
(1) Insert the instrument rack from the front of the instrument panel.
(2) Insert 1 into the holes at the top and bottom of the instrument rack and slide it toward the
instrument panel.
(3) Insert 2 into the rear holes at the top and bottom of the instrument rack.
(4) Screw 3 into 2 and push 1 into the instrument panel.
• Avoid applying excessive force to the screws as this may deform the mounting
bracket.
