Laser connections
Important Note: DC Voltage Sense Cable is only included with the purchase of the Novanta PS- 401
DC power supply. When using a power supply other than the PS-401, fabricate a DC voltage sense
cable to match your supply’s DC sense connections. In either case, attach the sense cable as described below.
1 1 Locate DC Power Cables and DC Voltage Sense Cable in the i401 and PS-401 ship kits.
2 Remove the two 6–32 cap screws and acrylic shield covering the +48V POWER terminal block on
the rear of the laser.
3 Remove the M10 bolt, flat washer, and external star washer from the +48V POWER terminal
block.
4 Remove the M10 hex nut, flat washer, and external star washer from –VDC GND terminal on the
rear of the laser.
5 Slide the black (negative) DC power cable over the –VDC GND terminal followed by the M10
external star washer, flat washer, and hex nut (see Figure 1-11).
6 Tighten the M10 hex nut to a torque of 20 N m (15 ft lb.) maximum using two wrenches. While
tightening the outer nut, hold the inner nut, the one against the laser’s rear plate, so that it does
not move.
7 Place the black (negative) DC voltage sense lead on the end of the –VDC GND terminal and
fasten using an M4 cap screw and flat washer. Carefully tighten the M4 screw to a torque value of
1.8 N m (16 in lb.) maximum.
8 Fasten the red (positive) DC power cable and red DC sense lead to the +48V POWER terminal on
the rear of the laser using the M10 bolt, flat washer, and star washer as shown in Figure 1-11.
Carefully tighten the M10 bolt to a torque of 7.4 N m (65 in lb.) maximum.
9 Replace the acrylic cover on the +48V POWER terminal block and fasten it in place using two 6–
32 cap screws.
Important Note: Do not overtighten the M10 fastener into +48V POWER terminal on the laser
because this may damage the threads.
DC power supply connections
If using another type of DC power supply, connect DC sense cables per the manufacturer’s
recommendations.
1 Verify that input AC voltage to the DC power supply is physically locked out or disconnected.
2 Attach the black (negative) DC power cable to the –VDC Ground Bus Bar on the PS- 401 power
supply using M6 (or 1/4 inch) fasteners (Figure 1-10).
3 Attach the red (positive) DC power cable to the +48 VDC Output Bus Bar on the PS- 401 power
supply using M6 (or 1/4 inch) fasteners.
