Electrical connections
(cont.)
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 rear (output) section and connect the black (–) DC power
cable from the v30 laser to the negative (–) output terminal.
3
Connect the red (+) DC power cable from the laser to the positive (+) 30 VDC output terminal.
4
On the supply’s front (input) section, connect the neutral wire from your AC voltage source, typically white, to the
terminal labeled “N” (AC Neutral).
5
Connect the hot wire from your AC voltage source, typically black, to the “L” (AC Line) terminal.
6
Connect the ground (earth) wire from the AC source, typically green, to the terminal labeled with the ground symbol.
Note:
Because AC input connections and requirements vary from country to country, customers must provide the appro-
priately sized AC power cable or wiring.
Control connections
Complete all control connections to the OEM v30 laser through the
Interface A
(DB-9) or
Interface B
(RJ45) connectors on
the v30’s rear panel. The interface connector receives tickle pulse and PWM Command signals and also serves as the con-
nection point for auxiliary signals between the laser and any parts handling, automation, or monitoring equipment. Refer to
the Technical Reference section for specific details about the OEM v30 user interface.
The OEM v30 control board differs from other Firestar v-Series models in that it does
not
incorporate a built-in tickle gen-
erator. If you are not using a SYNRAD UC-2000 Universal Laser Controller to operate the laser, you
must
provide
a 5 kHz, 1 µs tickle pulse between applied PWM signals.
Refer to the
Firestar v40 Operator’s Manual
and see
Controlling laser power
in the Technical Reference chapter for tickle signal
Warning
serious
personal
injury
Always use shielded cable when connecting your PWM Command signal source to the
PWM Positive
/
PWM Negative
connections. In electrically-noisy environments, long
lengths of unshielded wire act like an antenna and may generate enough voltage to
trigger uncommanded lasing.
