ESAB Replacing Fan Assembly on the SVI 300i cvcc Power Source Assembly Instruction

Brand: ESAB

Model: Replacing Fan Assembly on the SVI 300i cvcc Power Source

Type: Assembly Instruction

The two Nidec A30322-10 fan assemblies used in the

SVI 300i cvcc power source were replaced by ebm

W2E142-BB01-01 fan assemblies starting with

MFI723195. If replacing the Nidec fan assemblies, pro-

ceed as follows:

Before replacing part, make sure all primary input

power to the power source is disconnected.

NOTE: The Nidec and ebm fans are interchangeable

so use the same mounting holes in the sheet

metal.

1. Remove cover.

2. Remove the four mounting screws from the rear

panel.

3. Cut tie wraps holding the wire harness to the rear

panel.

4. Disconnect Faston terminals with wires from fan ter-

minals. These terminals can be disconnected from

the fan through access holes in the sheet metal.

5. Pull the rear panel away from the machine (about 2

to 3 inches) to allow for fan access.

6. Remove the two screws holding each fan in place.

7. Remove both Nidec fans from the unit.

8. Cut off and discard the Faston terminals from the

black and white wires in the harness which were

connected to the fan. Strip .25 of the insulation

from these wires. Connect the provided mating ter-

minals to these wires using a crimping tool.

The Faston terminals of the wire harness should

not be connected directly to the fan terminals. If

this is done, the Faston terminals will come in con-

tact with the case of the SVI 300i. Although the

Faston terminals are insulated, the insulation is not

sufficient and failures may occur. The pigtails con-

nected to the fan terminals should be used for in-

stallation.

9. Mount the new ebm fans.

10.Connect Faston terminals from fan pigtails to the

mating terminals that were just connected to the

black and white fan wires.

11.Reassemble the rear panel.

12.Tie wrap the wire harness back onto the rear panel.

13.Reassemble the cover.
