Electrical connections
The following procedures describe how to complete electrical connections to v30 lasers. OEM v30 DC
power cables are manufactured from #12 AWG wire and measure 1 meter (40 inches) in length.
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 to electrically isolate the laser when other equipment is grounded to
the laser’s DC power supply.
DC power supply
OEM v30 SAG/SWG lasers require a DC power supply capable of providing 30 VDC at 15 A minimum
(24 A peak for a minimum of 0.5 ms) while fan cooled (SFG) models require 30 VDC at 16 A (24 A peak
for a minimum of 0.5 ms). NOVANTA recommends our PS-2, a 30 V, 750 W DC power supply (shown in
Figure 1-6). AC input requirements for the PS-2 are 90–264 VAC (auto-ranging); single-phase (1Ø); 10 A
max; 47–440 Hz. To connect the PS-2 power supply, refer to Figure 1-6 and perform the following steps:

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 PS-2’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.
