3. RECEIVING AND

UNPAKING

WARNING : If any parts are damaged or missing.

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)

STORAGE AND

P;ANDLING

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

mm).

When the

mountinlg

surface is not horizontal , adjust with spacers.

(2) There are four mounting holes.

Use Ml0 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

in cross section.

(4) Do not mount the contactor with its front inclined downward.

This may result in

rnalfunction.

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

(6) When it is applied

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

OPERATlON

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:
