2. Wire remote control cord directly to terminal strip

within unit according to Section B.

B. REMOTE Terminal Strip 3T Information And

Connections (Figures 4-2 And 4-4)

WARNING: ELECTRIC SHOCK can kill; UN- EXPECTED OUTPUT can cause serious in- jury.

•Do not touch live electrical parts.

•Stop engine, and disconnect negative (−) battery cable from battery before making any internal inspection or connections.

•Do not connect to REMOTE 9 receptacle and terminal strip at the same time.

Since the OUTPUT (CONTACTOR) can be en- ergized from either the receptacle or terminal strip, it is vital to use only one remote control method.

MOVING PARTS can cause serious injury.

•Keep away from moving parts such as fans, belts, and rotors.

Terminal strip 3T, mounted on the lower front panel (see Figure 4-2), is included in case the plug supplied on the remote control cord is not suitable for connections to the REMOTE 9 receptacle RC3.

To make connections, proceed as follows:

1.Remove existing plug from remote control cord.

2.Open and secure lower front door.

3.Locate strain reliefs provided on lower front panel (see Figure 4-2).

4.Insert leads from cord through strain relief.

5.For Remote Electrical Cutoff Switch, remove jumper link between terminals N and P.

6.Connect leads to terminal strip 3T using terminal information provided in Section C.

7.Secure the cord in the strain relief.

8.Close and secure door.

C. Socket/Terminal Information (Figure 4-4)

The following lists the functions of the sockets of RE- MOTE 9 receptacle RC3 (see Figure 4-3), and the termi- nals of strip 3T (see Figure 4-4). The following socket/ terminal information is provided in case it is necessary to wire the auxiliary equipment cord.

With Socket Locations

Socket A/Terminal A:

Contact closure to Socket B/Terminal B completes the 115 volts ac contactor con- trol circuit; protected by circuit breaker CB3.

Socket B/Terminal B:

Contactor closure to Socket A/Terminal A completes the 115 volts ac contactor con- trol circuit.

Socket H/Terminal J:

Command reference; +10 volts dc.

Socket F/Terminal G:

Control circuit common.

Socket G/Terminal H:

Input command signal from wiper of re- mote control potentiometer; 0 volts equals machine minimum; +10 volts equals ma- chine maximum.

Socket C/Terminal C:

115 volts ac circuit common; also con- nected to welding power source chassis.

Socket D/Terminal D:

Up to 10 amperes of 115 volts ac, 60 Hz, with respect to terminal C (circuit common).

Terminals L and M of 3T:

Terminals supply 30 amperes of 115 volts ac, 60 Hz, auxiliary power. Terminal L is circuit common.

Terminals E/Terminal E or F:

Weld Voltage Feedback. Polarity determined by connection at terminal E (+) or F (−).

Terminal N and P of 3T:

Closed circuit between terminals N and P is normal condition. Open circuit between terminals N and P is Remote Emergency Electrical Cutoff condition.

Terminal I/Terminal K:

Machine chassis (Equipment Ground).
