1. GENERAL DESCRIPTION

(1) Ambient condition

The type CV vacuum contactor is manufactured in accordance with IEC 60470(2000).
The vacuum contactor should be used in the following conditions.

Table 1
Normal service condition

－Altitude : Less than 1000m
－Ambient temperature : －5℃ min. to +40℃ max.

Its average over a period of 24h
does not exceed +35℃

－Relative humidity : 45% min. to 85% max.
－Vibbration : 20Hz －9.8m/s

2

or less

CAUTION : Do not use in condition other than those specified

above , please consult .

(2) Locative condition

The location where the contactor is to be installed should be free from dust.
Corrosive gas and moisture.
When it is be used in a chemical plant or in outdoor panels,
take necessary precautions against corrosion,
water seepage and condensation.
See page 2.

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.

6F9G0154

(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.
