ELECTRICAL CONNECTIONS

• To allow proper heat dissipation, the shroud must be open at the front to allow cooling air to flow
away from the laser.
• Allow 3–4" (76–102 mm) of clearance between the front of the cooling fan and the rear of the
laser.
• To provide proper airflow, the cooling fan should have a diameter of approximately 4.5–5" (114–
127 mm) and must supply an airflow of at least 300 CFM distributed evenly over the length and
width of the laser's cooling fins.
Electrical connections
The following procedures describe how to complete electrical connections to both Keyswitch and OEM
v40 lasers.
DC power supply
v40 lasers require a DC power supply that provides 30 VDC at 24 A maximum. We recommend the
NOVANTA DC-5 DC power supply that supplies 30 VDC at 33 A. AC input requirements for the DC-5 are
90–132 VAC (low range) or 175–264 VAC (high range), single phase (1ø), 15 A max, 47–440 Hz.
To connect the DC-5 power supply for 120 VAC (low range) input, refer to Figure 1-7 and follow the
steps listed in the 120 VAC input operation section. If you are connecting the DC-5 for 240 VAC (high
range) input, refer to Figure 1-7 and follow the steps listed in the 240 VAC input operation section.
Do not reverse polarity when connecting DC power cables to your DC power source. Reversed DC
polarity will damage the laser's internal RF power supply. Carefully follow the directions below to
ensure that DC cable leads are properly connected to the correct DC output terminals.
Caution: Possible Equipment Damage
