DC-655

								N.A. Welding cables must be of proper capacity for the current and
								duty cycle of immediate and future applications.
								N.B. Extend lead #21 from control cable with terminal strip connectors
+21 - 21 41	4	2	31	32	75	76	77	or from 14-pin receptacle using #14 AWG or larger insulated wire
								physically suitable for the installation. An S16586-[LENGTH]
								remote voltage sensing work lead may be ordered for this purpose.
							C	Connect it directly to the work piece keeping it electrically
N.F.								separate from the welding work lead circuit and connection. For
							B
							A	convenience, this extended #21 lead should be taped to the
							32	welding work lead. (If the length of work lead circuit is
							31	short, and connections can be expected to be reliable, then
							2
							4	control cable lead #21 does not need to be extended and can be
N.B. & N.C.							GND	directly connected to terminal #21 on the terminal strip. Note
								that this is not the preferred connection because it adds error
NEGATIVE				POSITIVE			N.D.	to the NA-5/-5R voltmeter reading.)
							21	N.C. Tape up bolted connection if lead #21 is extended.
								N.D. Connect the control cable ground lead to the frame terminal
	N.H.							marked	near the power source terminal strip. The power
								source grounding terminal (marked		and located near the power
							BOLT TO CABLES FROM NA-5/-5R	source input power connections) must be properly connected to
							WIRE CONTACT AS'BLY	electrical ground per the power source operating manual.
		N.A.						N.E. The jumpers on the NA-5/-5R voltage board must be connected as follows:
							N.D. & N.F.	Connect red jumper to pin "S".
								Connect white jumper to pin "B".
								When using NA-5/-5R controls above Code 8300, the NA-5/-5R Inch Down
							TO WORK	button will not operate unless a jumper is connected between the two
								tab terminals, labeled "AUTO", located above the transformer on the
								NA-5/-5R Voltage P.C. board. This jumper, however, will disable the
						REMOTE VOLTAGE SENSING LEAD		Cold Starting/Auto-Stop/Touching-Work feature of the NA-5/-5R,
								permitting only Hot Starting techniques to be used.

DIAGRAMS

bove diagram shows electrode connected positive. To change polarity, power off, reverse the electrode and work leads at the power source.

efer to NA-5 or NA-5R Operating Manual for required NA-5 or NA-5R control box polarity connections. Also refer to note N.F.

FOR ADDITIONAL INSTALLATION INSTRUCTIONS, SEE NA-5 OR NA-5R OPERATING MANUAL.

For proper setting of switches on power source, see power source operating manual.

N.F. If lead #21 is to be connected to the terminal strip, connect to the #21 terminal that matches work polarity. This connection must be changed

whenever the electrode polarity is changed.

N.G. For proper NA-5/-5R operation, the electrode cables must be snugged under the clamp bar on the left side of the NA-5/-5R control box.

N.H. Illustration does not necessarily represent actual position of appropriate output studs. Refer to power source operating manual

for more information.
