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
