Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your IA240.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Be careful when handling the IA240. When plugged in, the IA240’s internal components generate heat, and
consequently the outer casing may feel hot to the touch.
You should also observe the following common wiring guidelines:
•
Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE:
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•
You can use the type of signal transmitted through a wire to determine which wires should be kept separate.
The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
•
Keep input wiring and output wiring separate.
•
When necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting the Power
Connect the 12 to 48 VDC power line to the IA240’s terminal block. If the power is properly supplied, the Power
LED will light up. The Ready LED will glow a solid green color when the operating system is ready (it may take
30 to 60 seconds for the operating system to boot up).
ATTENTION
This device is intended to be applied by a Power Supply, rated 12 to 48 VDC, 510 mA minimum requirements,
and it cannot disassemble by operators or service people.
