Wiring
The following procedure describes how to wire the
ATC. The ATC ports and buses are described in Figure 6.
CAUTION
Risk of Electric Shock
Disconnect the power supply before making electrical
connections to avoid electric shock.
ATTENTION
Risque de décharge électrique
Débrancher l'alimentation avant de réaliser tout rac-
cordement électrique afin d'éviter tout risque de
décharge électrique.
CAUTION
Risk of Property Damage
Do not apply power to the system before checking all
wiring connections. Short circuited or improperly con-
nected wires may result in permanent damage to the
equipment.
ATTENTION
Risque de dégâts matériels
Ne pas mettre le système sous tension avant d'avoir
vérifié tous les raccords de câblage. Des fils for-
mant un court-circuit ou connectés de façon incor-
recte risquent d'endommager irrémédiablement
l'équipement.
1. Wire the FC Bus Terminal Block. The ATC features
a blue, removable, 4-terminal FC Bus block that
fits into a board-mounted jack. Wire the FC bus as
shown in Figure 1.
Note:
Controllers can be daisy-chained by
inserting two wires into each connection.

2. Wire the SA Bus Terminal. The ATC features a
brown, removable, 4-terminal SA Bus block that
fits into a board-mounted jack. Wire the SA Bus as
shown in Figure 2.
Note:
- SA bus devices can be daisy-chained
by inserting two wires into each
connection.
- The SA BUS PWR terminal on the ATC
supplies 15 VDC, up to 210 mA. The
SA BUS PWR terminal can be used to
connect the 15 VDC power leads on
the SA Bus to power other devices
that are connected in a daisy chain
configuration. If a device has an SA
BUS PWR output, do not connect it to
the ATC SA BUS PWR output.
