STEP 5. Applying Power to the Controller
5.1 Pull all field wiring into the controller
1.
Pull all the field wiring into the controller cabinet, using conduit and the supplied knock-outs
taking care to
not pinch or strain wiring.
2.
Leave enough extra wire to make a service loop
.
3.
Also, pull the LAN cable into the cabinet for the CPU connection.
!
IMPORTANT:
Do not run low-voltage wiring in the same bundle or conduit with high-voltage
wires.
Running data (Reader Data and LAN) wires near high frequency wires can cause severe
communication interference and results in equipment or system failure.
5.2 Connecting Back-up Battery and Power Transformer to the Power Supply
CAUTION:
OBSERVE POLARITY WHEN CONNECTING THE BATTERY
.
CAUTION:
Risk of Electric Shock, Electrical Arcs, Fire or Burns if battery is not properly wired.
Reversing polarity can cause electrical shock and result in serious bodily injury.
1.
Attach the backup battery
(12 V / 8 A-hr or equivalent)
to the power supply
at the terminals marked
“ + BAT – ”
. The battery sits inside the cabinet in front of the power supply.
2. Wire the power transformer to the controller power supply (min. 18 gauge) at the terminals
marked “AC”
Example: Altronix 12 VDC Power Supply. Observe Terminal Markings & polarity of the Power Supply you purchased.
3. Plug the power transformer into the 115 AC 50 Hz wall outlet (power source).
4. Check DC volts output of the power supply inside the controller (should see 13.8 VDC).
5. CONNECT THE CPU POWER CONNECTOR TO THE CPU BOARD – POWER LED = SOLID/ON.
