Connecting
4
Connect a jumper wire (the same wire gauge as the other AC wires) between the termi-
nals 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 termi-
nals labeled “L2/N” and “L3/N”.
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 “L3/N”.
Control connections
All control connections to Firestar f-Series lasers are made through the 15-pin User I/O connector on
the rear panel. The User I/O port receives power commands from SYNRAD’s UC-2000 Universal Laser
Controller or FH Series Marking Head and also serves as the connection point for auxiliary signals be-
tween the laser and any parts handling, automation, or monitoring equipment.
Important Note: Because Firestar f200/f400 lasers are dual-tube lasers, all control connections (inputs,
outputs, and PWM Command signals) must be connected in parallel between both
User I/O connectors. This assures that both tubes are driven equally and that input
and output control signals are able to enable or disable both laser tubes simultane-
ously. See Figure 3-17 in the Technical Reference chapter for an example circuit.
UC-2000 Universal Laser Controller
SYNRAD 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 f100/f201 lasers or f200/f400 lasers
section below:
Note: Firestar 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
specications and connection details.
