2. Electrical Installation
2.1.
Voltage Considerations
Check the specification table or system drawings for proper line input voltage and supported relay
voltages. If there are any questions, contact Magnetek before applying power to the system.
WARNING
THE UNIT MUST BE WIRED TO THE CORRECT VOLTAGE. FAILURE TO DO SO MAY DAMAGE THE
SYSTEM.
NOTE:
The collision avoidance system should not be connected to lines containing excessive power up
transients or continuous commutator noise. A line conditioner may be necessary in some installations.
2.2.
Wiring Considerations
1. Do not connect or disconnect wiring or perform circuit checks while the power is turned on.
2. Power supply wiring shall be in a metal conduit and separate from any motor wiring.
3. Control wiring shall be in separate conduit and shall be kept as short as possible.
4. Please observe National Electric Code (NEC) when wiring electrical devices.
5. When cutting holes in the cabinet, take care to prevent metal filings from shorting the circuitry.
Remove any metal screws, metal filings, and wire clippings from inside of the unit.
6. Inspect to make sure no exposed wire has contact with any other wiring or terminals.
7. Suppressors are strongly recommended on all contactors.
2.3.
Wiring Instructions
1. Connect power to the power supply (85-264 VAC or 120-
370 VDC) terminals “+” and “-“.
2. Wire both relays according to Figure 4 and 5. The acceptable wire size is 24 to 14 AWG.
Please observe National Electrical Code (NEC) guidelines when wiring electrical devices.
3. Connect a ground wire to the dedicated ground terminal block.
4. Turn on the power and verify the green LED on the laser sensor is on continuously after a few
seconds. If that does not occur, turn the power off and recheck all wiring.
