,& WARNING ShockHazard. I nstallinglowand highvoltage
wire in sameconduitcouldresult in deathor serious
injury.
Donot run low andhigh voltage wire in the sameconduitunless
the insulationratingon ALL wiringis ratedfor 600V.SeeNEC
for moreinformation.
All wiring must be the proper size, properly supported
and protected by conduit. All wiring should be done per
applicable federal, state and local codes, standards and
regulations. Obey wire type and torque specifications printed
on the terminal blocks and neutral/ground connector.
Approved for copper and aluminum conductors.
Complete the following connections between the transfer
switch, main distribution panel, utility power and generator.
Use installer-supplied 300VAC or greater wire that complies
with Table 310.16 in the National Electric Code. Apply the
necessary correction factors and wire size calculations.
NOTICE improper installation can cause damage to the
circuit boards and shorten their life. Installing circuit
boards in live circuits will damagethe board and is not
covered by warranty. ALWAYSdisconnect ALL sources of
power prior to servicing.
° Removeall power prior to installing this equipment.
Failureto do so could cause internal damageto the board
when making electrical connections.
° Turn generator to OFFposition.
° Turn off utility power to the standby g_nerator and
Assure grounding electrode conductor is connected and
bonded per applicable federal, state and local codes,
standards and regulations.
9. Connect feeder conductors from transfer switch
breaker "GENERATOR CONNECTION" t erminals to
generator circuit breaker LINE1 and LINE2 terminals.
Each conductor must pass through hob of current
transformer before making connection.
10. Hug current transformer leads into "CTI" and "CT2"
terminals on transfer switch control board.
11. Connect conductor from transfer switch neutral
terminal to generator NEUTRALterminal.
Observe generator control panel labeling for
terminal identification.
