Wiring Details
See Figure 2 on page 7 to locate connectors and other components on the EC-BOS-6
AX
controller.
Make connections to the EC-BOS
AX
in the following order.
1.
Install any option boards (LON, RS-485, or modem) in option slots 1 and 2. See “Mounting Option
Cards,” page 8 for a general procedure. For complete details, refer to the specific mounting and wiring
guide that shipped with the option board.
2.
Connect supplied earth grounding wires (with spade connector) from the earth ground lug on the
EC-BOS-6
AX
and any accessory modules (if used) to a nearby earth grounding point. See “Grounding”
below for details.
3.
Prepare power wiring (leave the unit powered off). See “Power Wiring” for details.
4.
Connect communications cables. See “Communications Wiring,” page 14 for ports available on the
EC-BOS-6
AX
base unit. For ports on any installed option board (LON, RS-485, modem) see the specific
mounting and wiring guide for any additional details.
5.
If I/O accessory modules are installed, connect I/O wiring. Refer to the appropriate mounting and wiring
guide for complete details.
6.
Connect the backup battery to the EC-BOS-6
AX
battery connector, and apply power to the unit. See
“Power Up and Initial Checkout,” page 16.
Grounding
An earth ground spade lug (0.187") is provided on the base of the EC-BOS-6
AX
for connection to earth ground.
For maximum protection from electrostatic discharge or other forms of EMI, connect the supplied earth
grounding wire to this lug and a nearby earth ground (see
Figure 3 on page 13). Keep this wire as short as
possible.
Power is provided for EC-BOS-6
AX
plug-in accessory modules through the 20-pin accessory connectors.
However, you should also connect the earth ground spade lug of each accessory module to ground in the same
manner.
Power Wiring
The EC-BOS-6
AX
must be powered by an approved 15 Vdc power source. This can be either
1
an external wall
mount AC adapter (EC-WPM- XX ) or the DIN-mount power module (EC-NPB-PWR/-UN). The EC-BOS-6
AX
controller does not include an on/off switch. To apply power, plug in the power connector to either the
EC-BOS-6
AX
(if EC-WPM- XX ) or the EC-NPB-PWR/-UN.
The EC-BOS-6
AX
controller does not include an on/off switch. To apply power, you either:
•
if EC-WPM-XX, plug in the power connector to the EC-BOS-6
AX
.
•
if EC-NPB-PWR, plug in its 2-position power connector.
•
if EC-NPB-PWR-UN, energize the AC circuit (90-263Vac) wired to that module.
1. In some markets, a fourth power option is available: an EC-Net
AX
IO-34 accessory module, which is a combination of
the EC-NPB-PWR module and two EC-Net
AX
IO-16 modules (plus two extra relays). Please refer to its mounting and
wiring instructions document for more details. For general information on accessory modules, see “About Accessory
Modules,” page 9.
