FIELD INSTALLED OPTIONS

For installation of compatible field installed options (see the ACCESSORIES section of this manual and refer to the instructions included with those options.

REQUIRED EQUIPMENT-CONTROL CABLE CONNECTIONS

Follow the instructions below which are appropriate for the wire feeder that will be used.

LN-7 to CV-300

a)Turn the CV-300 Power switch to the "OFF" posi- tion.

b)Connect the LN-7 control cable to the wire feeder receptacle on the CV-300.

c)See OUTPUT CONNECTIONS for connection of work and electrode cables.

LN-25 to CV-300

a)Turn the CV-300 Power switch to the "OFF" posi- tion.

b)Plug a K484 jumper plug into the CV-300 wire feeder receptacle.

c)See OUTPUT CONNECTIONS for connection of work and electrode cables.

WARNING

The output terminals are energized at all times when the K484 is plugged in.

------------------------------------------------------------------------

LN-742 to CV-300

a)Turn the CV-300 Power switch to the "OFF" posi- tion.

b)Connect the LN-742 control cable to the wire feeder receptacle on the CV-300.

c)See OUTPUT CONNECTIONS for connection of work and electrode cables.

Connection of Remote Control (K857)

NOTE: The K864 Remote Control Adapter is required to install the K857.

Plug the K864 Remote Control Adapter into the power source's 14-pin receptacle. Plug the K857 Remote Control into the 6-pin receptacle of the K864 adapter. If possible, tape the Remote cable to the heavy output leads, so they can protect the smaller Remote cable from damage and abuse.

OUTPUT CONNECTIONS

Output cables must have Magnum Twist-Mate™ plugs for connection to the CV-300. Order K852-95 for con- necting 2/0-3/0 (70-95 mm2) cables. Refer to S18737 for instructions on installing these plugs.

Use the shortest possible cable lengths. See Table A.1 for recommended cable sizes based on length.

Connect the positive output lead to the terminal marked "+". The negative output lead can be hooked to either the low inductance terminal (marked " ") or the high inductance terminal (marked

" ").
