4 Connect a jumper wire (the same wire gauge as the other AC wires) between the terminals labeled
“L1/L” and “L2/L”.
5 Connect the other hot wire, typically black, to the input terminal labeled “L2/N.
6 Connect a jumper wire (the same wire gauge as the other AC wires) between the terminals labeled
“L2/N” and “L3/N”.
Important Note: The neutral white, typically white, is not used in this wiring scheme.
Two individual single-phase circuits (120–264 VAC)
1 Follow your facility’s Lockout/Tagout procedures and verify that input AC power to the DC power
supply is physically locked out or disconnected.
2 Connect the safety ground (earth) wires from both circuit 1 and circuit 2, typically green, to the
input terminal labeled “GND”.
3 Connect the AC hot wire from circuit 1, typically black, to the input terminal labeled “L1/L”.
4 Connect the return (neutral) wire from circuit 1, typically white, to the input terminal labeled “L2/N”.
5 Connect the hot wire from circuit 2, typically black, to the input terminal labeled “L2/L”.
6 Connect the return (neutral) wire from circuit 2, typically white, to the input terminal labeled
Control connections
All control connections to F201 laser f201 lasers are made through the 15-pin User I/O connector on the
rear panel. The User I/O port receives power commands from NOVANTA’s UC-2000 Universal Laser
Controller or FH Series Marking Head and also serves as the connection point for auxiliary signals between
the laser and any parts handling, automation, or monitoring equipment.
UC-2000 Universal Laser Controller
NOVANTA recommends the use of a UC-2000 Universal Laser Controller to generate pulse width modu-
lated (PWM) Command signals that control the laser’s output power. To connect a UC-2000 Controller
(available separately), perform the steps described in the appropriate f201 laser section below:
Important Note: F -Series lasers can also be controlled from an alternate user-supplied
Command signal source. Refer to Controlling laser power in the Technical Reference chapter for
control signal descriptions and refer to User I/O connections, also in the Technical Reference chapter, for
signal specifications and connection details.
