4.7 Installation
In a typical installation (see Figure 11), the generator (2) and utility
power connect to the ATS (1). Power from the utility or the gnera-
tor (2) is fed to the main circuit breaker panel from the ATS (1). The
circuit breaker in the ATS is the service entrance disconnect for the
installation.
When the utility power fails, the ATS will sense the failure, the gen-
erator will start, and when sufficient generator voltage is available,
the ATS will switch. All loads will receive power from the generator.
When utility power returns, the ATS will switch all power back to
the utility source and the generator will shut down after its defined
cooled down period.
4.7 Generator Start Connection
The generator start contact connection terminal blocks are located
on the RTC100 controller.
N ote: Prior to making the generator start connection to the aTS, set the generator
control selector switch to the OFF position to prevent an unwanted generator start.
Control wiring, such as the generator start wires, must be run in a separate conduit
from the power cables.
A normally open and normally closed contact as well as a common
from the RTC-100 control board are wired out to this set of terminal
blocks. The RTC-100 controller initiates the start
by closing or opening these contacts. The start signal requirements
of the generator will determine which contact is used to control the
start up. Use the proper wire size as listed by the
(Genset) manufacturer
4.8 Preliminary Checks
After the ATS enclosure is installed and power cables are connected
to the equipment, thoroughly inspect the unit to ensure that no
tools were left inside and that the cabinet is free of debris. If nec-
essary, use a vacuum cleaner to remove any and all construction 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.

For Catalogue #EgSC100aSE, EgSCa100aSE, EgSC200aSE and
EgSCa200aSE
This switch is equipped with integral over-current protection.
Continuous load current not to exceed 80 percent of switch rating.
This Transfer Switch is rated for use on a circuit capable of deliver-
ing not more than 10,000 rms symmetrical amperes, 240 volts maxi-
mum.

5.1 Preliminary Checks
Step 1: Check all loads connected to the ATS to ensure that they are
ready to be energized.
5.2 Energize the Switch
Step 1: With the service entrance barrier removed use a voltmeter to
measure the line-to-line and the line-to-neutral voltages on the
line side of the circuit breaker. Confirm the utility voltage is cor-
rect then replace the service entrance barrier.
Step 2: Ensure the generator control selector switch located on the
standby generator is set to the OFF position. If so equiped,
remove the control fuse from the generator control panel to
ensure the generator does not iniate a start during this phase of
the preliminary check. Open the generator power source circuit
breaker located on the generator assembly.
Step 3: Close the service entrance disconnect circuit breaker in the
switch to connect the ATS to the utility power source voltage.
If the ATS unit is not already in the UTILITY position, and the
voltage is acceptable, the solenoid will engage and the contac-
tor will automatically switch to the UTILITY position.

Step 4: Replace the control fuse in the generator control panel removed
in Step 2 of Section 5.2. Position the generator control selector
switch, located on the standby generator, to the AUTOSTART
position. (It may also be labeled REMOTE START or AUTO.).
Close the generator power source circuit breaker opened in
Step 2 of Section 5.2.
