INSTALLATION (continued)
1--2

De–energize the conductors before making

any line or auxiliary circuitry connections.

Be sure that Normal and Emergency line

connections are in proper phase rotation.

Place engine generator starting control in the

OFF position. Make sure engine generator is not

in operation.

Power connections
AWiring Diagram is furnishedwith the Series 200
ATSE.All wiri ng must be made in accordance with the
local codes.
Do notrun cables in front of the transfer switching
device. Conductors can be bundled ont he right side of
the transfer switching device. Maintain proper electrical
clearancebetween the live metal parts and grounded
metal: 13 mm minimum.
It is not necessary to remove the barriers from the
transferswitching device to install the conductors.If
you do remove them, however, be sure to reinstall the
barrierscarefully.
Connect main source and load cond uctors to clearly
marked power terminals on the transfer switching
device. Be careful when stripping insulation from the
conductors;avoid nicking or ringing the conductor.
Removesurface oxide s fromconductors by cleaning
with a wire brush. Followconductor manufacturer’s
instructionswhen aluminum conductoris used. Apply
joint compound to conductor,then carefully wipe away
excesscompound. Tighten the terminals to the torque
specifiedon the label on the transfer switchingdevice.
Three conductor spacers are included with 150, 200,
and230 ampere transfer switching devices. When
installing power conductors, run them through the
conductor spacers as shown in Figure 1–4. Positionthe
spacers within 38 mm of the power terminals.
NOTICE

Three conductorspacers must be located as

shown for 150, 200, and 230 ampere transfer

switching devices.

Engine Starting Contacts
The engine control contact connections (if used) are
locatedon the transfer switching device. Connect signal
wiresto appropriate terminals as specified in TableA
and shown in Figure 1–5.
