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

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 5.5mm2in 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
