ATC-300/900 Breaker Based Transfer Switch
Figure 39. Horizontal Power Panel
Step 3:
Turn the generator OFF at the generator control panel.
This will prevent unexpected activation of the generator.
Step 4:
Connect the Engine Generator Start wires as shown in
Section 4.7. This contact is CLOSED whenever the
engine generator is needed, and should be connected to a
generator controller.
NEVER
connect directly to a starter
solenoid or ignition system. See the Genset manufacturer
instruction leaflet for recommended wire sizes and loca-
tion procedures.
Step 5:
Apply Utility (Source 1) power. If the switch is properly
applied for the system voltage ordered, the display should
work and the Source 1 Available white LED should light
(Figure 40). Using a voltmeter, check for proper system
voltage on Source 1 and load terminals. Check all phases
on a 3-phase switch. Voltage measurements should be
taken phase to phase and phase to neutral.
