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
OR WITHIN THE ATS EQUIPMENT.
CHECK THE ATS EQUIPMENT NAMEPLATE 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 13), 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.
