Preinstallation Guidelines and Installation Procedures
Utility
Requirements
The Innova 322C ion laser requires electrical power for the power
supply, as well as a supply of water to cool both the laser head and
the power supply.
Please have your plant engineer read this section carefully to ensure
the optimal working conditions for your new laser.
Electrical Service
The AC electrical service for the Innova 322C ion laser power
supply must meet the specifications listed in Table 1.
Attached to the power supply is a ten-foot power cable without a
connector attached to the free end. The cable is Type W - 4/4,
#4AWG, four wires. The green/yellow wire has to be connected to
the building ground. You must provide the hardware necessary to
connect this cable to your electrical service. Consult applicable electrical codes for your area to select this hardware. For safety reasons
as well as performance reasons, the electrical service has to be established such that all three phases are symmetric to building ground
(e.g., WYE connection with center tap to building ground). The
voltage measured between phases must be 215 VAC with a phase
balance of <3% between phases. The voltage between each phase
and building ground must be 124 VAC with a phase balance of <3%
between phases. Refer to Table 1 on page 2 for more information.
The service must have a main power disconnect switch located in
close proximity to the laser. It shall be clearly marked as the disconnecting device for the laser, and shall be within easy reach of the
operator.
The Innova 322C ion laser uses an input power cord which is
typically not approved for direct connection in Europe but is
however suitable for operation in other geographical areas. The
power cord is safe and does meet all requirements.
In order to achieve the laser's specified input voltage, European
installations normally use a Transformer. The Innova 322C ion
laser power cord is suitable for connection to a transformer, but
must not be directly connected to a AC mains circuit as distributed in Europe.
Do not directly connect a Innova 322C ion laser to the AC power
in an European installation, without first verifying that the voltages are correct and that the wiring used meets all of the local
regulatory requirements.

The laser system will operate properly within the line voltage tolerance provided that the voltage between each
pair of phases is within 3% of each other. Power companies almost always provide balanced 3-phase power,
but if a heavy load is connected asymmetrically, the line balance can be disturbed. This results in excessive
ripple current through the capacitors of the DC filter. This ripple current degrades the noise performance of the
laser and shortens the lifetime of the filter capacitors.
If the end user application is sensitive to momentary partial (output) interruptions (G.I.) or momentary total
(output) gain interruptions (Dropouts), the laser system must only be connected to a dedicated, balanced clean
power source or motor generator to minimize the occurrence of such events due to facility power related
anomalies.
Consult applicable electrical codes for your area to select appropriate electrical service hardware. Power
supply is fused at 80 amps.
Static pressure is the inlet pressure measured under conditions of zero flow.
Pressure Delta is the pressure differential between inlet and drain.
The cooling water of any Ion laser can condense moisture from the air when the temperature of the cooling
water is lower than the dew point of the air. The system must not operate under these conditions since it will
lead to catastrophic failure in the power supply. See “Selecting the Correct Cooling Water Temperature” on
page 3 for more details.
Coherent supplies a 60 micron water filter with the system.

Preinstallation Guidelines and Installation Procedures
Cooling Water
The Innova 322C ion laser requires a flow of cooling water for the
laser head as well as for electrical components inside the power
supply. Because properties of the cooling water are of critical importance to the performance of the laser, make certain that the cooling
water in your work area conforms to the specifications listed in
Table 1 at all times.
Check local and state regulations which may control use of city
water for cooling. For instance, some regulatory codes will not
allow the discharge of cooling water into the sewer system.
The cooling water temperature must not fall below the ambient
dew point. If this does occur, condensation will form inside the
power supply and may cause catastrophic damage. In some situations it may be necessary to provide humidity control for the
laser environment.
Selecting the
Correct Cooling
Water
Temperature
The cooling water of any Ion laser can condense moisture from the
air when the temperature of the cooling water is lower than the dew
point of the air. The system must not operate under these conditions
since it will lead to catastrophic failure in the power supply. Under
most conditions, it is recommended to select the inlet cooling water
temperature to 30°C (86°F). The following information provides
recommendations for operating conditions outside of the normal
temperature and humidity range.
The conditions that lead to a situation where there can be condensation are warm and humid weather combined with water that is cooler
than the surroundings. High risk conditions which will lead to
condensation are:
•
Operating the laser in a room that is not air conditioned in high
humidity conditions
•
Using cooling water that is not temperature controlled
•
Leaving the cooling water on when the laser is not operating
for extended time periods
The parameters required to determine if the cooling water temperature will lead to condensation is:
•
Room temperature
•
Relative humidity
3
Innova 322C Ion Laser Preinstallation Manual
Since the weather conditions change, these factors need to be periodically check especially in the spring and summer seasons. In environments that are air conditioned, we recommend setting the cooling
water temperature to 30°C (86°F). As explained below for conditions that are not air conditioned, we recommend that the cooling
water temperature be increased to the air temperature to avoid
condensation in humid climates.
The recommended minimum inlet cooling water temperature is
provided in Table 2 and Table 3 for the complete operating temperature range of the Innova 322C ion laser. Note that the first table is
for temperature on the Celsius scale and the second is for temperatures on the Fahrenheit scale. To use this chart, find the row with the
closest room temperature. Next read across until you find the
column with the nearest relative humidity for the room with the
laser. The number in the box is the recommended temperature for the
inlet cooling water. If a closed loop cooling system is being used
then select this temperature as the temperature set point. As an
example, if the current room temperature is 28°C and the relative
humidity is 68%, then the recommended inlet cooling water temperature is 35°C and the nearest relative humidity is 70%.

The minimum inlet cooling water temperature should account for variations in cooling water temperature with the
thermal load, temperature stability of the cooling water system, and seasonal variations in cooling water temperature.
Selecting the cooling water temperature must also take into account
changes in the cooling water temperature. For a closed loop cooling
water system, there can be variations in the water temperature due to
changes in the thermal load and the response time of temperature

The minimum inlet cooling water temperature should account for variations in cooling water temperature with the
thermal load, temperature stability of the cooling water system, and seasonal variations in cooling water temperature.
controller. The number given by the table will be the minimum water
temperature that must be observed for the current room temperature
and humidity conditions.
In many climates, the cooling water temperature must be changed
due to seasonal variations in the ambient conditions. For example in
times of high relative humidity and high room temperatures, the
cooling water temperature will have to be increased to avoid problems with condensation. Under extreme conditions of temperature
and humidity, the laser must not be operated as noted in Table 2 and
Table 3. This can be solved by air conditioning the room with the
laser to reduce both the room temperature and the humidity.
When using tap water as cooling source, seasonal variations in the
water temperature often can lead to conditions that will produce
condensation. In this case, mixing some hot water with the inlet
cooling water will be required to eliminate condensation or alternatively reducing the room temperature and humidity with an air
conditioning system.
Closed-Loop
Cooling System
If your cooling water does not meet specifications, you must install
a closed-loop heat exchanger to obtain optimum performance from
your laser. A fully integrative and recommended heat exchanger,
Coherent part number 1117614, is available to meet these requirements.
5
Innova 322C Ion Laser Preinstallation Manual
If your application demands critical beam pointing stability, power
stability, or frequency stability, the use of pressure and temperature
regulators on the facility cooling water system may also be advantageous.
Environmental
Requirements
Ambient
Temperature
The room in which your laser is located must be maintained at a
temperature of 10 to 30°C (50 to 86°F).
Relative humidity
The humidity of the room must fall within the range of 10 to 90%
and be non-condensing. Refer to Table 2 and Table 3 to determine
the acceptable temperature / humidity relation.
Altitude
The maximum operational altitude for the Innova 322C ion laser is
2,000 meters maximum.
Site Preparation
Planning the
Workspace
To assist you in planning sufficient workspace for your Innova 322C
ion laser, dimensions of the laser system are given in Figure 1 and
Figure 2. Enough space must be left around the laser head so that the
components inside can be reached easily for alignment and maintenance.
Umbilical Cord
The laser head and power supply are connected through an
eight-foot umbilical cord. This cord must not be crimped or bent
sharply. To avoid crimping, use a bend radius of at least 30 cm
(12 in.) for the umbilical cord. The umbilical cord may be configured to exit the laser head either horizontally on the table surface or
vertically straight downward at the table edge.

Work Surface
The Innova 322C ion laser is a precision instrument whose performance depends on its environment. Vibrations can be transmitted to
the laser head from the surface on which it rests, causing beam
pointing instability and beam amplitude fluctuations. To minimize
vibrations, the laser head must be placed on a stabilized optical table
and isolated from mechanical contact with other equipment.
Unpacking
the System
The Innova 322C ion laser is shipped in two crates: one contains the
power supply, the other the laser head. Accessories, including the
remote control module, are packed in separate boxes. A packing list,
which details all the ordered items, is included in the shipment.
Please check items received against this packing list.
Please advise your receiving department to perform the damage
inspection procedure prior to signing the bill of lading.
8
Preinstallation Guidelines and Installation Procedures
Damage
Inspection
Carefully inspect each crate and note any damage. All Innova 322C
ion laser crates are shipped with rough handling indicators affixed to
their front and back. Examine these indicators upon receipt. If the
indicator bar is red, the crate has received handling which may have
damaged the contents. Indicate any such signs on the bill of lading.
Report any damage immediately to the shipping carrier and to the
Coherent Order Administration Department, 800-438-6323.
Uncrating
To minimize the risk of functional or cosmetic damage to your laser
system, uncrate the laser head and power supply at the installation
site.
To prevent serious damage, care must be taken when cutting
wrapping materials from any of the items contained in the
crates, particularly around the laser head and the umbilical
cord. This warning also applies to opening accessory boxes and
the unpacking of their contents.

Preinstallation Guidelines and Installation Procedures
Only the magnet water jacket is connected to ground. No part of
the tube or reservoir can touch the case.
External Interlock
7.
Use a 1/8 in. Allen wrench to remove the two screws from the
power supply and the two screws from the umbilical support
bracket which will hold the umbilical connections cover in
place.
8.
Slide the umbilical connections cover over the umbilical
holder and bracket so that the screw holes on either side of the
center opening are aligned with those on either side of the
umbilical holder. Secure this assembly using two of the shorter
screws provided.
9.
Secure the top of the umbilical connections cover to the power
supply using the four screws removed above.
10.
Connect the power supply power cord to the facility power.
The external interlock is located on the rear panel of the Innova
power supply, as shown in Figure 3. Terminals, 5 and 6, of terminal
strip TB1 must be connected for the laser to operate. The factory
installed jumper may be replaced with an external interlock circuit.
The External Interlock circuit may be wired to a door switch to
shut off the laser when a person enters a designated restricted
area.
The external interlock has an open circuit voltage of 20 to 28 VDC
and a short circuit current of ≤12.0 mA. Under no circumstances will
an external voltage or current source be connected to this circuit.If
the external resistance connected between the terminals is less than
10Ω, the laser is functional and will operate from the remote or
external computer control. If the resistance is greater than 100,000Ω,
the laser is disabled and will not operate. To assure proper functioning of your laser system, design your external interlock circuit to
have a resistance less than 10Ω when closed and a resistance greater
than 100,000Ω when open. External interlock circuitry must be
isolated from all other electrical circuits or grounds.
If the external interlock is open (jumper not installed or restricted
area door open), the laser will not operate. The remote control
module display will read: External Interlock.

Innova 322C Ion Laser Preinstallation Manual
External Switch
There are two external switches available on TB1 on the rear panel
of the Innova power supply. One switch, between terminals TB1-1
and TB1-3, is normally open when the laser is off. The other switch,
between terminals TB1-2 and TB1-3, is normally closed when the
laser is off. Once the main contactor engages, the switch between
TB1-1/3 closes and the switch between TB1-2/3 opens. (The main
contactor closes 25 seconds after pressing the ON button and
remains closed until the plasma tube is de-ionized.) The external
switches may be used, for example, to turn on warning lights outside
of the lab indicating that the system is ionized and possibly lasing.
This switch is isolated from all other laser circuits. It is rated for
30 VAC, 12 Amps (maximum). It is not internally protected by fuses
or other overcurrent protection devices.
Refer to Figure 3 for TB1 pin-outs.
Heat Exchanger
Control (option)
On the rear panel of the Innova power supply is a plug labeled TO
HEAT EXCHANGER(Figure 3, Item 15). An interconnect cable
(15 ft., 4.6 m) attaches this plug to a similar plug, J17 on the
Coherent Small Frame Heat Exchanger. This provides operating
power to the heat exchanger and water level feedback to the power
supply. A cable strain relief is provided on each end with an attached
bracket and Phillips head screws.
Remote Control
Module
Connection
The remote control module cable has a phone jack connector which
plugs into the receptacle labeled REMOTE on the rear panel of the
power supply (Figure 3, Item 8). Plug in the jack and make sure the
connection is secure.
Rotating the
Umbilical on the
Laser Head
To allow versatility in the location of the laser head, the umbilical
assembly can be rotated from its normal position so that it hangs
straight down from the end of the laser head. To make this change
proceed as follows:
1.
Shut down the laser and disconnect power.
2.
Position the rear of the laser head so that at least six inches
protrudes over the edge of the table.
3.
Loosen the four screws which retain the umbilical mount to the
rear bezel of the laser head.
4.
Pull out slightly on the umbilical assembly to release it from
its mount, and then push the umbilical downwards.
16

5.
Rotate the bracket to align the four clearance holes on the
bottom of the head.
6.
Push the assembly firmly upwards until it seats in the new
location (Figure 5) and tighten the four retaining screws.
7.
Restart the system.

Rack Mount
Installation
Before commencing this procedure, switch off the laser system and
disconnect power at the source. Detach the umbilical connections at
the rear of the power supply.
1.
Remove the handles on the sides of the power supply by
removing the four socket head cap screws (two per handle
accessed from outside the power supply) with a 3/16 inch
Allen screwdriver.
2.
Each Rack Mount slide bracket assembly is made up of three
components: the chassis bracket (smallest), the sliding bracket
(the one in the middle), and the rack bracket (the largest).
Disassemble the sliding bracket and rack bracket as a unit from
the chassis bracket by depressing the lever exposed as the
chassis bracket is pulled out from the other two brackets. The
chassis bracket, has five mounting holes that match five holes
with threaded inserts on each side of the power supply chassis.
3.
Using the hardware already installed on the power supply,
mount one chassis bracket on each side of the power supply
chassis. Mount them so the sliding brackets can be slid onto
them and the spring lever is towards the rear of the chassis.
Slide the sliding brackets onto the chassis brackets until they
lock in place, extended from the rear of the power supply.
4.
Mount the rack brackets (Coherent Part Number: 1403-0337)
with the extensions (Coherent Part Number: 1403-0338) if
needed, onto the equipment rack using the mounting hardware
kit (Coherent Part Number: 1403-0340) as shown in Figure 6.
5.
Align the power supply and sliding brackets to the rack
brackets and slide the unit in as far as it will go. Push in on the
spring lever locking mechanisms on the sliding brackets so the
unit can be slid all the way in place.
The handles provided for the rack mount option are not
intended to be used to carry the power supply if the unit is
removed from the rack.
6.
Mount the handles to the angles using the #8-32 x 5/8 in. flat
head screws.
7.
Remove the side screws in the front from the top cover of the
power supply. Mount the angles to both front sides of the
power supply using the #10-32 x 1/2 in screws so that the
handles face forward.

Preinstallation Guidelines and Installation Procedures
Output Mode
Measurements
When your system is installed, you may verify that the output mode
meets specifications.
If an application demands routine examination of the laser mode,
several options are available which differ widely in cost and accuracy of measurement. The simplest and most inexpensive device is
a mode cup, a short focal length lens or mirror which can be used to
project the beam onto a wall or screen for visual inspection.
Use extreme caution when projecting an expanded laser beam
with a mode cup. The expanded beam is sufficiently intense to
cause severe eye damage.
For more precise measurements, a beam scanner, spectrum analyzer
or M2 meter such as the Coherent ModeMaster™ Beam Propagation
Analyzer can be used. Contact Coherent Technical Support at
800-367-7890 for more information on how this equipment can be
used with your Innova 322C ion laser.
