wire. On the other end of the wire, combine with the short lead from VR53 and attach a
connector (wire and lead in the same terminal).
– Attach the single-conductor end of the white wire to the
neutral
terminal on the ac input
filter FL51. Connect the other end (with the VR53 lead) to the neutral terminal on the ac
power connector. The neutral input of the filter is the terminal post on the “Line” end
farthest away from the side of the chassis.
– Using the primary ac wire included in the AC Power Connector Hardware package,
prepare a 6-inch piece of #16 black stranded wire. Attach a connector to one end of the
wire. On the other end, combine with the free lead from VR53 and attach a connector
(wire and lead in the same terminal).
– Attach the single-conductor end of the black wire to the
hot
terminal on ac line filter
FL51. The hot terminal is the one on the “Line” end closest to the side of the chassis.
Attach the other end of the black wire (with the VR53 lead) to the terminal of circuit
breaker CB51 closest to the chassis deck.
– Using the primary ac wire included in the AC Power Connector Hardware package,
prepare a 4-inch piece of #16
black
stranded wire. Attach a connector to each end of the
wire.
– Attach one end of the black wire to the
line
terminal on the ac power connector. Attach the
other end of the black wire to the available terminal of circuit breaker CB51.
Set the ac power cord aside for now. It will be connected only after all preliminary tests have
been completed. Note that while the connectors of the power cord receptacle are recessed, it is
nonetheless possible to make contact with hot connectors if the socket is probed.
Never let
children play with the power cord.
– Prepare a 7-inch long #16 black stranded wire. Attach quick-disconnect terminals on each
end of the wire.
– Attach one end of the wire prepared in the previous step to the
Hot-2
post on the right
channel PWB. Attach the other end of the wire to the
RYL51
NO
post. Note that the
terminal legend for the relay is given on the top side of the device. Insert the connector
