Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your CN2510.
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 CN2510. When plugged in, CN2510’s internal components generate
heat, and consequently the board may feel hot to the touch.
You should also observe the following common wiring rules:
y 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.
y 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.
y Keep input wiring and output wiring separate.
y Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting CN2510-8/16’s Power
Connect CN2510’s 100-240 VAC power line to its AC connector. If the power is properly
supplied, the “Ready” LED will show a solid red color until the system is ready, at which time the
color changes to green.
Connecting CN2510-8/16-48V’s Power
To connect CN2510-8/16-48V’s power cord to its terminal block, follow the steps given below:
V+ V-
ON OFF
1. Loosen the screws on the V+ and V- terminals of CN2510-8/16-48V’s terminal
block.
2. Connect the power cord’s 48 VDC or -48 VDC wire to the terminal block’s V+
terminal, and the power cord’s DC Power Ground wire to the terminal block’s
V-
terminal, and then tighten the terminal block screws.
(Note: CN2510-8/16-48V will still operate properly if the 48V/-48V and DC
Power Ground wires are reversed.)
If the power is properly supplied, the “Ready” LED will show a solid red color until the system is
ready, at which time the color changes to green.
