Auxiliary Input Power Connection
Instructions
Use the appropriate size leads, at least 14AWG – 2wire
with ground
1.
Remove two Phillips Head screws on right side of
front panel of hinged door to access terminal strip.
2.
Remove a plug button and install a box connector to
provide strain relief for the input power leads.
3.
Strip off 1/4"(6.4mm) of insulation from the leads
and route them through the strain relief.
4.
Locate the 4-terminal blocks, numbered #48, #49,
and #50. These are to be used to bring in auxiliary
power. Terminal block #50 is used for the input
ground connection. This termi- nal block is color-
coded green and yellow for easy identifica- tion.
Terminal blocks #48 and #49 are to be used to
connect the input power circuit. (See Figure #3).
5.
Using a flat-head screwdriver with a blade
dimension of 0.137"(3.5mm) x 0.020"(.51mm), insert
the screwdriver into the square hole next to the
mounting hole to be used on the ter- minal strip. The
screwdriver should be inserted until it bottoms out.
This opens the screwless cage clamping style wire
inser- tion port. With the cage clamp opened insert
the wire into the round port until it bottoms out.
While holding the lead securely, remove the
screwdriver from the terminal block. This closes the
cage clamp onto the lead holding it securely. Any
open port on blocks #48, #49, and #50 may be
used.
Terminal blocks 48 and 49 are shipped connected to the
contacts of CR2 and CR3 by leads 531 and 532. These
relay contacts are also connected to the 4-pin Travel
connector and the 3-pin Flux connector located on the
bottom of the MAXsa™ 10 Controller. CR1 is available
for a separate customer connection, but it will turn ON
and OFF with CR2. Therefore, if Lincoln auxiliary
equipment is to be used, connecting 115VAC to the
terminal strip is all that is required to power the devices.
NOTE: The contacts of CR1 are not connected to
terminals #48 and #49 when shipped. Applying power
the #48 and #49 terminals will not transfer voltage to the
CR1 relay. Connect leads from the #48 terminal to the
#4 terminal and from the #49 terminal to the #3 terminal
to supply power to the common contacts of the relay.
Once input power is applied to the terminal strip, this
voltage is always on terminal strip blocks #3, #4 (if
connected), #11, #17, and #18. These are the inputs to
the solid state relay contacts. Input voltage is also
present on terminal strip blocks #7, #8 (if connected),
#15, #21, and #22 due to the N.C. contacts on the
relays. When the CR1 relay is energized, input power is
transferred to terminal strip blocks #5 and #6 (if
connected). When the CR2 relay is energized, input
power is transferred to terminal strip block #13. When
the CR3 relay is energized, input power is transferred to
terminal strip blocks #19 and #20. CR1 and CR2 will be
turned ON and OFF at the same time.
