Step 5 Carefully insert the pins of the option card into the socket of the appropriate option card slot.
The mounting holes on the option board should line up with the standoffs on the base board. If they
do not, the connector is not properly aligned.
Press until the option card is completely seated.
Step 6 Place the custom end plate that came with the option card over the connector(s) of the option card.
Step 7 Plug the battery connector plug into the battery connector on the EC-BOS-6
AX
.
Step 8 Set the battery and bracket assembly back over the option card slots, with the mounting holes aligned
with the standoffs.
Step 9 Place the four screws through the battery bracket, end plates, and into the standoffs on the
EC-BOS-6
AX
base board. Hand tighten these screws.
Step 10 Replace the cover.
About Accessory Modules
The EC-BOS-6
AX
has a 20-pin, right-angle, Euro-DIN connector that accepts custom-built accessory modules.
The connector provides power and signal lines to any connected modules, and is located on the end of the
EC-BOS-6
AX
opposite to the option cards.
Warning • Power to the EC-BOS-6
AX
must be OFF when inserting or unplugging accessory modules. Wait
for all LED activity to stop (all LEDs to be off).
• Also, do not connect live voltages to the inputs or outputs of an I/O module (EC-Net
AX
IO-16 or
EC-Net
AX
IO-34) while it is in an “un-powered state” before plugging the module into an
EC-BOS-6
AX
.
• Otherwise, damage to the I/O module and/or the EC-BOS-6
AX
controller may result!
Each accessory module has a DIN-mount base, and provides two (2) 20-pin connectors that allow you to “chain”
multiple accessories (see Procedure 1 on page 5). Table 2 lists the currently available accessory modules.
