4.5 Wiring
POWER CONDUCTORS AND CONTROL WIRING MAY HAVE VOLT-
AGE PRESENT THAT CAN CAUSE SEVERE PERSONAL INJURY OR
DEATH. DE-ENERGIZE ALL POWER OR CONTROL CIRCUIT CONDUC-
TORS BEFORE BEGINNING TO PERFORM ANY WIRING ACTIVITY TO

CHECK THE ATS EQUIPMENT NAMEPLATE AND THE ATC-100 FOR
RATED VOLTAGE. IT SHOULD BE THE SAME AS THE UTILITY AND
GENERATOR LINE VOLTAGES. OPERATING THE EQUIPMENT ON
IMPROPER VOLTAGE CAN CAUSE EQUIPMENT DAMAGE.
4.6 Installation
In a typical installation for critical loads (see Figure 15), the ATS
(1) and the generator (2) are connected to the power supply. The
ATS (1) and emergency distribution panel (3) receive utility power
from a dedicated breaker in the utility service panel (4). The ATS
and emergency panel receive generator power from the generator
(2). Power from the utility feeds the utility panel.
