GETTING STARTED PAGE |12
E-mail: [e-mail]
web: www.Novanta.com
Getting Started
Use information in this section to prepare your i401 laser for operation. The or-der of information
presented in this section is the same as the order of tasks that you will need to perform. The best way to
get your laser ready for operation is to start at unpacking and work your way through connecting.
This section contains the following information:
Introduction – introduces the i401 laser, lists important features, and describes i401 nomenclature.
Unpacking – provides important information about unpacking your i401 laser.
Inventory – displays and describes all components shipped with your i401 laser.
Mounting – describes how to attach your i401 laser to a mounting surface.
Connecting – explains how to connect cooling tubing, power, and control cabling.
Introduction
The Introduction section includes subsections:
•I401 nomenclature
•Model numbers
The i401 laser is a new addition to Novanta i401 series of high-power lasers. This single tube 400 W laser
features an integrated RF power supply with no external RF cables. The compact, single- tube design
mounts easily to flatbed cutters, robotic arms, or gantry systems making integration into your
production line simple and fast.
i401 features include:
•Built-in electromechanical shutter
•Built-in gas purge port
•TCP/IP web-based Internet interface
•Color-coded LEDs mirror user output status
•Field-replaceable integrated RF modules
•“Industrial-strength” ±5 V to 24 VDC I/O
•Built-in internal humidity sensor
•Beam output pre-aligned to within ±1.0 mm
•Duty cycles from 1% to 100% (CW)
•Low 6 kW heat load

UNPACKING PAGE |13
i401 nomenclature
i401 lasers are divided into two distinct functional categories: Key switch and OEM models. OEM lasers,
like the i401, do not incorporate key switch or shutter functions required by CDRH and EN 60825- 1
regulations because they are designed as components for integration into larger processing systems by
the Original Equipment Manufacturer (OEM) or System Integrator who bears full responsibility for
meeting the appropriate laser safety requirements for systems incorporating Class 4 lasers.
Although i401 lasers are available only as OEM lasers, they do include a built-in electromechanical shutter
assembly.
Model numbers
The last three characters in the i401 model number serve to designate the functional category, cooling
method, and model version. The functional category is indicated by either a “K” for Key switch or “S”
(Switch-less) for OEM models. The next letter indicates the cooling method: “W” for water-cooled units,
“F” for fan-cooled units, and “A” for air-cooled lasers (the cooling method, the “W,” is omitted on all i401
lasers since they are all water-cooled lasers). The last letter in the model number indicates the current
model version beginning with “B.”
Unpacking
The Unpacking section includes subsections:
•Incoming inspection
•Packaging guidelines
•Unpacking the i401
•Removing the lifting handles
Incoming inspection
Upon arrival, inspect all shipping containers for signs of damage. If you discover shipping damage,
document the damage (photographically if possible), then immediately notify the shipping carrier and
Novanta, Inc.
The shipping carrier is responsible for any damage occurring during transportation from Novanta, Inc. to
your receiving dock.

UNPACKING PAGE |14
Packaging guidelines
•To prevent equipment damage or loss of small components, use care when removing packaging
materials.
•After unpacking, review the Inventory section and verify that all components are on hand.
•Do not lift or support the laser using the cooling fittings; lift the laser by the lifting handles or
base plate only.
•Save all shipping containers and packaging materials, including covers and plugs. Use these
specialized packing materials when shipping the laser to another location.
•When packing a laser for shipment, be sure to remove all accessory items not originally attached
to the laser including beam delivery components, cooling tubing, etc.
•Refer to packaging instructions drawings in the Technical Reference section for details on
packaging i401 lasers using Novanta supplied shipping materials.
•When storing or shipping water-cooled lasers, remember to drain all cooling water from the laser
and then cap the open fittings to prevent debris from entering the coolant path.
•i401 lasers are heavy and awkward to move. Use appropriate lifting techniques, additional
personnel, and/or hoisting equipment to prevent a risk of injury when rigging this equipment.
Warning: Serious Personal Injury
Lifting or moving the i401 laser poses a potential for injury. Use appropriate lifting techniques
and/or equipment to prevent a risk of injury. In some cases, you may require assistance from
additional personnel to safely unpack and move this equipment.

dynamically in multiple axes) using the factory-installed mounting feet. To use a four-point mount, the
variation in mounting surface flatness must not exceed 1.02 mm (0.040").
To install a i401 (with feet) using the four-point mounting method, perform the following steps:
1Determine whether you will use metric (ISO) or inch (SAE) fasteners to mount the laser. Four M10
(metric) cap screws and M10 flat/split washers are included in the ship kit.
2Refer to the i401 outline and mounting drawing (Sheet 1 of 2) for Option ‘A’ mounting dimensions,
then drill and tap four M10 × 1.5 or four 3/8" (UNC or UNF) holes into your mounting surface.
These holes should correspond with the holes labeled “A” shown in following figure.
3Carefully place the i401 laser on the mounting surface so the holes in the mounting feet line up
over the threaded holes in the mounting surface.
4Place a split washer and flat washer on each cap screw and insert the fasteners through the feet
into the mounting surface. Turn the screws by hand until the threads fully engage.
5Evenly tighten all four fasteners to a torque of 40 N m (29 ft lb.).
Important Note: Each mounting foot also contains a 9.65 mm (0.380") dowel pin guide (labeled
“B” in the following) for applications that require precision positioning for alignment purposes.
Caution: Possible Equipment Damage
Novanta does not recommend mounting lasers in a vertical “head-down” or “tail-down” orientation.
If you must mount your laser in this manner, please contact the factory for limitations as a vertical
orientation increases the risk of damage to the laser’s output optic.

Important Note: After the laser is fastened into position, remove the lifting handles if necessary
Four-point mount without feet
Use this scheme to mount the laser to a horizontal or vertical surface (or to a surface that will move dy-
namically in multiple axes) by fastening directly into the laser’s base plate. To use a four-point mount, the
variation in mounting surface flatness must not exceed 1.02 mm (0.040").
To install a i401 (without feet) using the four-point mounting method, perform the following steps:
1Raise the i401 laser and place support blocks under the base plate.
2Unscrew the four M10 cap screws fastening the feet to the bottom of the i401 laser and remove
the factory-installed mounting feet.
3Refer to the i401 outline and mounting drawing (Sheet 2 of 2) for Option ‘B’ mounting
dimensions, then drill four 10.6 mm (close fit) or 11.2 mm (normal fit) thru holes in your mounting
Caution: Possible Equipment Damage
When removing the mounting feet, raise the laser by placing support blocks under the base plate.
Do not lay or place the i401 laser on its side or top, even temporarily, because the sheet metal
covers are not designed to support the weight of the laser. Always support and mount the laser
using the mounting feet or base plate to avoid damaging the laser.
