O & M Manual for the CHGENLC Automatic

Transfer Switch with ATC-100 Control

7.4.1.4 Ground Bar

Note:

The 100 A ground and neutral bars are the same. Refer to

Figure 35 for the correct location.

Step 1:

Turn the utility (Source 1) power off and turn the genera-

tor (Source 2) control selector switch to the “OFF” posi-

tion before attempting to replace the ground bar

Step 2:

Disconnect all wire cables from the ground bar.

Step 3:

Remove the 1.5 in. long screw at the top of the ground

bar (see Figure 31) using a Phillips screwdriver.

Figure 31. Replacing the Ground Bar.
Step 4:

Remove the screw in the black base using a blade screw-

driver or 0.25 in. socket or nut driver (see

Figure 31). Remove the ground bar.

Step 5:

Secure the new ground bar to the base plate using the

hardware supplied.

Step 6:

Insert the 1.5 in. long screw into the top of the ground

bar. Use the hardware supplied if necessary.

Step 7:

Reconnect all wire cables to the ground bar.

Step 8:

Apply utility (Source 1) power and place the generator

control selector switch in the “AUTO” position after the

ground bar has been replaced. Test the system for proper

functionality.

7.4.1.5. Replacing the Contactor

Figure 32. Replacing the Contactor.

Note:

If you are replacing the contactor in a 100 A or 200 A SE ATS, the

service entrance breaker must be removed first. Also jumpers between the

generator breaker (inside the ATS) and the E1, E2 terminals on the genera-

tor (Source 2) side of the contactor must be removed. Follow Steps 1

through 4 in Section 7.4.1.9 (for 100A & 200A Service Entrance breaker)

and Steps 3 & 4 in Section 7.4.1.10 (for 100A & 200A generator breaker).

Step 1:

Turn the utility (Source 1) power off and turn the genera-

tor (Source 2) control selector switch to the “OFF” posi-

tion before attempting to replace the contactor.

Step 2:

Note their location then disconnect the twelve (12) red

wires from the contactor (see Figure 32).

Note:

All wires connected to the contactor are labeled to ease

identification.

Step 3:

Remove the four (4) screws securing the contactor to the

base plate using a blade screwdriver or 0.25 in. socket or

nut driver. Remove the contactor.

Step 4:

Following the replacement steps for the 100 A or 200 A

lugs (see Sections 7.4.1.7 and 7.4.1.8), remove the lugs

from the old contactor then install the lugs on the new

contactor.

Step 5:

Secure the contactor onto the base plate using the hard-

ware supplied.

Step 6:

Reattach the twelve (12) red wires to the contactor.

Examine each wire to find the name then refer to Figure

32 for the correct connection point.

Step 7:

Reconnect all wire cables to the contactor as per their

original connections.
