ELECTRICAL CONNECTIONS
Important Note: The negative (–) side of the DC input to the laser is internally connected so that
the laser chassis serves as DC power ground. You should isolate the laser's DC power supply so
that the only grounded connection is at the laser. Alternatively, you can mount the laser chassis on an
insulating pad or film in order to electrically isolate the laser when other equipment is grounded to the
laser's DC power supply.
120 VAC input operation
1. Verify that input AC power to the DC power supply is physically locked out or disconnected.
2. Locate the 30 VDC output terminals on the power supply's output section and connect the black
(–) DC power cable from the laser to the negative (–) output terminal.
3. Connect the red (+) DC power cable from the laser to the positive (+) 30 VDC output terminal.
4. Locate the 5-pin terminal strip on the power supply's input section, under the protective Snap-On
cover.
5. Connect a jumper wire (16 AWG or heavier) between terminals 1 and 2.
Important Note: Because AC input connections and requirements vary from facility to facility,
customers must provide the AC power cable or wiring.
6. Connect the neutral wire, typically white, from your voltage source to terminal "N" (AC Neutral).
7. Connect the AC hot wire, typically black, from your 120 VAC source to the terminal labeled "L"
(AC Line).
8. Connect the ground (earth) wire, typically green, from your AC voltage source to the terminal
labeled with the ground symbol.
240 VAC input operation
1. Verify that input AC power to the DC power supply is physically locked out or disconnected.
2. Locate the 30 VDC output terminals on the power supply's output section and connect the black
(–) DC power cable from the laser to the negative (–) output terminal.
3. Connect the red (+) DC power cable from the laser to the positive (+) 30 VDC output terminal.
4. Locate the 5-pin terminal strip on the power supply's input section, under the protective snap on
cover.
Important Note: Because AC input connections and requirements vary from facility to facility,
customers must provide the AC power cable or wiring.
5. Connect one of the two AC hot wires, typically black, from your 240 VAC source to the terminal
labeled "L" (AC Line).
