3. RECEIVING AND UNPACKING

WARNING : If any parts are damaged or missing.
Do not install that has been damaged.

Make the following checks after unpacking :

(1) Check if there is any damage , foreign matter trapped , or water seepage

into the contactor.

(2) Check the nameplate to see if the specifications on the plate are correct.

(3) Check the contact wear gauge and control cable.

(4) Check the tripping rod (Latched type).

4．STORAGE AND HANDLING

When the contactor is to be stored over a long period , the storage area
should be dry and dust free area.
If the contactor is left outdoors or in adverse conditions , corrosion
from gas , rust or insulation deterioration may result.

CAUTION : In handling , do not throw or drop contactor.
The contactor may break.

5．INSTALLATION

When installing , protect from dust. Particularly when the contactor
is installed while the building is under construction , shield it from
cement dust and other foreign matter.

The following precautions should be taken.

(1) The mounting surface must be horizontal (level : less than ±1mm).

When the mounting surface is not horizontal , adjust with spacers.

(2) There are four mounting holes.

Use M10 bolts to securely mount the contactor.

(3) In wiring the main circuit terminals , ground terminals and control
circuit , wires should be given sufficient length to be flexible.
The ground wires should be more than 5.5mm

2

in cross section.

(4) Do not mount the contactor with its front inclined downward.
This may result in malfunction.

(5) Do not touch the vacuum interrupter surface with soiled hands.

(6) When it is applied to a capacitor load , be sure to used a space heater
to keep humidity low.

CAUTION : Do not install on energize contactor that has been bad condition.

９．OPERATION

The drive unit for the electromagnet is installed in the bottom frame.
Molded and wired on the printed circuit.
The closing circuit can be operated using either in AC or DC by the drive unit.
The optional latch trip circuit uses DC as standard.
When a latched contactor is operated using AC power, it is recommended that a
Capacitor trip device be used.

The standard operating voltage is as follows:

Non-latched type(normally energized) : 100－240 V AC /100－220V DC
Latched type :100－240V AC /100－250V DC closing voltage
:100－110V DC tripping voltage

NOTE：● Electrical trip－free circuit must be prepared outside the contactor.

● A stable DC power source such as battery is recommended for the
control circuit.
If DC power source is not available, employ a AC closing and a
Capacitor trip.

● Be sure to use the control connector between No.3 and No.13

10．Trial operation

Warning : Make sure main power is OFF.

After mounting and wiring of the vacuum contactor, make the following inspections.

1) Check for any loose connections.

2) Check for any wiring errors. Perform this test with only the control circuit energized.
confirm that the operation is correct. For the latched type contactor, check that the
latch correctly engages and trips when the close/trip signals are applied. Also,
manually trip the contactor using trip lever to verify proper operation.

11．INSPECTION AND MAINTENANCE

To maintain the function and performance of the vacuum contactor for a long period
of time, the following inspections and maintenance procedures are recommended.

The intervals between inspections may vary depending on the conditions of use and
the environment under which the contactor is used. The initial inspection should be
carried out within one year of the start of equipment operation, and the succeeding
check intervals should be determined according to the result of the initial inspection.
See Section 2 for use under special environment as in outdoor cubicles.

(1) Patrol Inspection(every 1－6 months)

With the cubicle energized, visually check from out side the cubicle according to
the check list of Table 4,5.

WARNING : When opening the door of the cubicle, do not come close
to danger area.

12．CRITERIA FOR DURABILITY

(1) Electrical service life
The electrical service life of the vacuum interrupter is defined by the electrode wear the
number of open/close operations (mechanical life).
To determine the electrode wear, measure the gap between the lever and washer
(dimension A) in a closed start , as shown in Figure8. With the vacuum interrupter
closed, if a contact wear gauge or a 1.0mm thickness gauge cannot be inserted ,
this means the end of life is reached.
For the components listed below, replacement or detailed inspection and cleaning
are recommended after the indicated number of operations.

Table 8 Electrical service life

Parts . name Electrical service life
Vacuum interrupter 100,000 operations or 15 years

Auxiliary switch 100,000 operations or 10 years
Drive unit 100,000 operations or 10 years
Movable conductor 100,000 operations or 15 years

Hence, parts should be replaced around electrical service life operations.

(3) Service life of capacitor

Opening and closing of the capacitor produces sever conditions for contactors,
such as high frequency inrush current and interpole recovery voltage more than
twice the normal voltage.

The criteria of the maximum number of the capacitor current switching operations
is shown in the graph below. The vacuum interrupter should be replaced when the
number of switching operations in the graph is reached.
