Auxiliary Input Power Connection Instructions
Use the appropriate size leads, at least 14 AWG – 2 wire 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 A.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 CON-
TROLLER. 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 to 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 trans-
ferred 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 trans-
ferred to terminal strip blocks #19 and #20. CR1 and CR2 will be
turned ON and OFF at the same time.
