4.8 Preliminary Checks
After the ATS enclosure is installed and power cables are con-
nected to the equipment, thoroughly inspect the unit to ensure
that no tools were left inside and that the cabinet is free of debris.
If necessary, use a vacuum cleaner to remove any and all con-
struction or installation debris from the equipment.
Read and understand all labels on the equipment. Review and
understand the wiring diagrams supplied with the equipment.
Note any optional accessories that may have been furnished with
this unit and review their operation.
Verify that the phase-to-phase line voltages of both the utility and
generator power sources are the same and that they match the
rated voltage as indicated on the ATS ratings label.
4.9 Terminal Block Wire Installation and Removal
Proceed with the following steps and associated figures to install
or remove terminal block wiring.
Step 1:
Figure 20 shows two tension clamp terminal blocks.
There is a large one and small one, but the operation is the
same for both. A small tool, such as a blade screwdriver,
will be pushed into the square hole next to the wire hole
and a wire will be inserted into the larger circular hole on
the outer edge.
Figure 20. Tension Clamp Terminal Blocks.
Step 2:
Begin by inserting a small, blade screwdriver into the
square (tool) hole with the flat surface of the screwdriver
against the back wall of the hole (see Figure 21). With a
little bit of force, push the screwdriver in on a slight angle
toward the center of the clamp. Be sure to slide it in until
it clicks. You will then see the clamp open in the wire
hole.

Step 3:
Once the screwdriver is in place, obtain a stripped wire
(strip about 0.25 in.) and insert it into the larger circular
wire hole. Push the wire in until it can go no further (see
Figure 22).
