2. Equipment Preparation:
a). Check nameplate to assure switch system voltage and amperage is correct. Any discrepancy
should be immediately reported to a Zenith representative.
b). Lock open breakers to normal and emergency lines.
3. Cabinet Preparation:
a). A small amount of cabinet work is required before the cables are connected. Cover the
switch and the controls to avoid metal fragments from entering mechanical and electrical
components.
b). Standard cable entry is through the top or side of the cabinet. Fig. 2 below shows one
suggested knockout order. For a guide to assist in the hole layout, refer to Appendix A,
page 17.
4. Cable and Wire Connections:
a). To remove possible oxide, clean cable conductor with a wire brush and apply a contact
oxide inhibitor. (On aluminum cables use a stainless steel wire brush). Insert cables into
appropriate lugs.
'·b).
Connect all auxiliary wires for external electrical operation. Example:; E-start, remote
alarm lights or buzzers, motor control contacts, etc. Allow enough slack in wires to
allow movement of the ATS (approx. 1ft.).
5. Prior to the unit's energization:
a). Remove any debris incurred due to shipment or installation.
b). Inspect the unit, especially the cable and wire connections.
