Progressive Industries EMS-LCHW50 - Manual (Page 6)

6. Strip back all conductors 3/8 inches and attach ring terminals to
green ground wires. (See Picture A) If this wire is solid wire, do
not use ring terminals. Loop the wire around the ground screw.
7. Remove the lid from the EMS. Remove the digital display and
pack of screws and then back off the six set screws from top of
contactor. (L1, L2, etc.)
8. Take the jumper cable and connect it to the input side by sliding
through the wire restraint on the end of the EMS control box and
then connect black to L1; white to L2; red to L3; green to ground
screw. (See Picture B) Torque down set screws and ground nut to
secure connections.
9. The cable that came from the transfer box connects to the output
side of the EMS control box in the same manner. Next slide the
black wire through the current sensor containing the green tape and
connect to T1, then connect the white wire to T2. Now slide the
red wire through the other current sensor and attach to T3. The
arrow that is on the sensor needs to face T1 and T3. Next, attach
the green ground wire to the ground screw on side of box. (See
Picture B)
Make sure that the conductor’s colors match up across
from each other. Torque down the set screws and ground nut to
secure connections.
10. Connect the loose end of the jumper cable to the transfer switch.
See wiring diagram on transfer switch if needed.
11. Double check all connections to ensure they are secure.
12. Secure cable ends by tightening down strain reliefs over the input
and output wires. Do not over tighten as this could bite through
insulation and cause a short.
13. Set time delay jumper on the circuit board. Factory setting is for
15 seconds. Remove jumper to change setting to 136 seconds
(02:16). See Features Section on time delay to determine which to
use. (See Picture B)
14. Plug in display. (See Picture C)
15. Attach lid with the six black machine screws provided and attach
transfer switch lid.
16. Mount the EMS control box.
17. Installation is complete. Next, plug in and follow operating
instructions.
