RECEIVING & HANDLING Page 7

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

RECEIVING
Upon receipt of the equipment, make an immediate inspection for any damages which may have occurred

during shipment. When the contactor is received it should be unpacked sufficiently to inspect for concealed
damage and to determine that the shipment is complete and correct. If any damage is found it should be
noted prior to accepting the shipment if possible.
Check for things such as, damage to the container, water seepage or moisture on the contactor. Check the
nameplate to confirm that the ratings meet the intended application.

If any parts are damaged or missing, file a claim immediately with the carrier and notify the Toshiba sales
office. Try to give as much information as possible when filing a claim.

HANDLING & STORAGE
Vacuum contactors should be handled with care to avoid damage. Contactors should be kept in an upright

position and moved with suitable equipment.
If the contactor is to be stored over any length of time, the packing material should be restored for protection

during that period. Where conditions permit, the packing should be left intact until the contactor is ready for
installation. Store the contactor in a dry and dust free area. It should not be left outdoors or in adverse
conditions. If unprotected, corrosion, rust and insulation deterioration will occur.

APPLICATION PRECAUTIONS

1) Verify that the voltage and current applied is within the specified ratings. (See application
table, page 5).

2) When the contactor is used with an induction heater facility, the switching life of the vacuum
interrupter is approximately 250,000 operations. The vacuum interrupter should be replaced
after 250,000 operations.

3) When the contactor is applied to a capacitor load, be sure to use a space heater to keep
the temperature above the dew point and prevent condensation. Be sure to use a heater
adequately sized for the compartment in which the contactor is installed. The contactor
should always be applied with a protective power fuse.

INSTALLATION
During installation, protect the contactor from dust and falling debris.
The following precautions should be taken,

1) The mounting surface should be horizontal (level: ±1 mm). If the mounting surface is not
level, adjust with spacers or shims.

2) The contactor base has four (4) mounting holes. Use M8 or 5/16 bolts to securely mount
the contactor.

3) In wiring the main circuit, wires should be gi ven sufficient length to be flexible for service.
The ground wires should be #10 AWG or larger.

4) Avoid touching the surface of the vacuum interrupter with soiled hands. You can damage
the silicon finish on the interrupter. If the interrupter becomes dirty, simply clean it with a
non-tracking cleaner such as rubbing alcohol.

CONTROLS
The drive unit for the closing coil assembly is installed in a cavity in the molded frame housing. The

closing circuit can be operated by applying either AC or DC to this 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 control voltage (factory preset) is 120V AC. To operate at other ratings see the

selection chart below.

Fig. 2 Control Voltage Selection for Closing Coils

The following is a list of the available trip coil voltages for a latched type contactor:
24 V DC 32 V DC 48 V DC

125 V DC 250 V DC

TRIAL OPERATION
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 the trip lever to verify proper operation. For latch kit adjustment and
maintenance please refer to manual no. 6F9G0132 - Installation Instructions of Latch Kits
for HCV-5HA.
