General Description
The AtmosPure Re-Gen Gas Purifier consists of three distinct systems:
A. Circulation System B. Purifier System C. Regeneration Control
Circulation System
The circulation blower continually circulates the inert gas inside the glove box through the Gas Purifier to remove oxygen and moisture. As the blower circulates the glove box inert atmosphere through the purifier column, water molecules are adsorbed by the molecular sieve. Molecular sieve is a synthetic zeolite that adsorbs all molecules less than 10 angstroms in size. Oxygen molecules are removed from the inert gas by reacting with the copper catalyst and forming copper oxide.
Purifier System
A six inch diameter stainless steel column contains 5 lbs of molecular sieve for H2O removal and 5 lbs of a reactant copper catalyst material for O removal. The purifier is equipped with components necessary for regeneration of the molecular sieve and copper scavenging media.
Attached to the column are:
Two isolation valves (manually operated). These valves are kept
open during circulation of the glove box gas through the purifier and MUST BE CLOSED during the regeneration procedure.
Three solenoid valves for connecting 4% hydrogen/inert gas mixture,
exhaust vent, and vacuum. These are located at the back of unit.
A flow meter for 10-25 CFH regulation of the 4% hydrogen/inert gas
mixture during regeneration.
A 180 watt electric heating coil imbedded in the purifier media. The
heating coil is used in regeneration of the catalysts.
Ceramic fiber, high temperature insulation. An exterior metal case to protect all the components.

Regeneration Control
Regeneration is controlled by a microprocessor which automatically sequences the solenoid valves during the regeneration cycle. The regeneration cycle restores the molecular sieve and copper catalyst. It is programmed for the following time functions:
Initial 2 minute purge to allow adjustment of 4% hydrogen/inert gas
mixture flow rate to 10-25 CFH. (10 CFH Helium/4% Hydrogen, 20 CFH Nitrogen/4% Hydrogen, 25 CFH Argon/4% Hydrogen).
Heat cycle – 3 hours. Purge cycle – 2 hour – 4% hydrogen/inert gas mixture flows through
purifier (heat also remains on).
Vacuum cycle – 8 hours minimum (continues until manually shut-off
and red LED flashes).
The control panel contains push button switches for automatic cycling (H2 SET, HEAT, H2 PURGE, VACUUM). The lighted display shows which stage the regeneration process is in.
NOTE: Refer to Chapter 3, Chapter 4 and Chapter 5 for more detailed descriptions of performance features, control functions, operating instructions, and safety features.

Support Requirements
In the preparation of installing the Gas Purifier at the glove box site, please consider the following:
A bench or stand that rests on the floor or fixed to the wall, but not both,
may be appropriate. 35" to 40" (889mm to 1,016mm) is typical for standing height (Labconco stands offered in Chapter 7 vary from 33" to 40" or 838mm to 1,016mm). The stands Labconco offers include a convenient place on the right side shelf to support the AtmosPure Re­Gen Gas Purifier. See Figure 1-1 in Chapter 1.
Exhaust Requirements for the Regeneration Vent Valve
The vent valve exhausts 4% hydrogen/inert gas during the regeneration process and must be vented safely to the outside or exhausted to a fume hood. The regeneration vent valve is exhausted through the gas flow regulator. An open compression fitting is attached to the gas flow regulator and can be used to connect the exhaust hose from the Regeneration Plumbing Kit. Refer to Chapter 7 to purchase the Regeneration Plumbing Kit and Chapter 3 for start up.
Electrical Requirements
Electrical receptacles should be located nearby for connecting the Gas Purifier and the controlled atmosphere glove box. The Gas Purifier is rated 100-115V, 10A or 230V, 5A. One exterior outlet for a vacuum pump connection is located on the rear of the Gas Purifier and is rated for 100-115V, 8A or 230V, 4.5A. A single shared vacuum pump can be used for glove boxes configured with auto pressure control, please see Chapter 7: Accessories to order the AtmosPure C.A. COM Cable (6-pin). Accessory oxygen or moisture monitors can be programmed to provide automatic control of the Gas Purifier’s blower. Please see Chapter 7: Accessories to order the AtmosPure Oxygen/Moisture Monitor Cable (9-pin), Oxygen or Moisture Monitor, and Sealed Electrical 9-pin Pass­Through. Chapter 3 details all the connections for proper start-up. Figure 3-8 shows a typical connection diagram for electrical connections.

Connecting the Circulation Plumbing
The circulation plumbing continuously circulates the inert gas atmosphere from the controlled atmosphere glove box and purifies it by removing oxygen and moisture. The connections from the 3/4" inlet/outlet compression fittings must be made to the glove box. Depending on the neoprene lined tubing kit or stainless steel tubing kit selected, route one line from the inlet of the Gas Purifier to the outlet of the glove box. Refer to Figures 3-1, 3-2, and 3-8. Next, route the outlet of the Gas Purifier to the inlet of the glove box. A continuous tubing loop for Gas Purifier circulation is now established. Be
sure to properly tighten all the 3/4" compression fittings at least 1-1/4 turns past finger tight as leaks will affect Gas Purifier performance. The
orientation of all the compression fittings must be properly set per Figure 3-3. Should your glove box have 3/8" compression fittings (such as Labconco polyethylene glove boxes), use the 3/4" to 3/8" adapter kits to route the circulated air through the neoprene lined hose kit. Refer to Chapter 7 to order all circulation kits and adapter kits.
Note: The Gas Purifier ships fully regenerated and ready to use. Keep the isolation valves (manually operated) closed until ready to use. The isolation valves (Figure 3-4) must be closed until the glove box inert gas atmosphere is below 5000 ppm. Opening the isolation valves before the Gas Purifier and glove box are ready for operation will cause a loss in oxygen and moisture removal capacity.

Connecting the Regeneration Plumbing
The Regeneration Plumbing allows the copper catalyst and molecular sieve to be regenerated as needed. The regeneration process takes 13 hours and may be completed overnight. Refer to Figures 3-1, 3-3, and 3-8.
First, locate the tank of 4% hydrogen/inert gas mixture. Using the AtmosPure Regeneration Tubing Kit, route the tubing from the 4% hydrogen gas mixture pressure regulator to the valve inlet per Figures 3-1 and 3-8. The 4% hydrogen mixture provides the gas to restore the copper catalyst. Be sure to orient the ferrules properly and install the tube insert into the flexible line on both ends per Figure 3-3. Tighten the compression fittings on both ends 1-1/4 turns past finger tight.
Second, locate the vacuum pump and route the vacuum line from the vacuum pump to the vacuum solenoid valve located on the back of the AtmosPure Re-Gen Gas Purifier per Figure 3-1. The vacuum line connection tubing is included in the Gas Purifier Regeneration Tubing Kit. Again, be sure to orient the ferrules properly, install the tube inserts, and tighten the compression fittings 1-1/4 turns past finger tight. An alternate view for connection to the vacuum solenoid valve is provided in Figure 3-5. If one shared vacuum pump will be used and shared between the controlled atmosphere glove box and the Gas Purifier, then the AtmosPure C.A. COM cable (6-pin) must be connected between the Gas Purifier and the back of the glove box Auto Pressure Control (refer to Figures 3-1, 3-6, and 3-8). If shared with the controlled atmosphere glove box (only with auto pressure control), then plug the vacuum pump into the back of the glove box (refer to Figure 3-6). If a dedicated vacuum pump will be used for the Gas Purifier, plug the vacuum pump into the electrical outlet on the back of the AtmosPure Re-Gen Gas Purifier (Figure 3-1).
Third, the vent valve is exhausted through the 10-25 CFH flow control valve as viewed in Figure 3-1. The vent line must be exhausted to the outside or to a fume hood. From the Regeneration Tubing Kit, install the exhaust line to the flow control valve and route the tubing to the outside or to a fume hood. Again, properly install the tubing per Figure 3-3.

Initial Start-up of the Gas Purifier for Removal of Oxygen and Moisture
Do not open the isolation valves (Figure 3-4) until the inert atmosphere in the controlled atmosphere glove box main chamber has been reduced below 5000 ppm for both oxygen and moisture. The Gas Purifier arrives fully regenerated and ready for use. Usually 5000 ppm can be attained through 200 evacuation and fill cycles of inert gas into the glove box. Once 5000 ppm or less is achieved, the Gas Purifier isolation valves may be opened and the blower turned on. Simply turn the blower ON as identified on the control panel per Figure 3-7. Once turned ON, the blower circulates inert gas air from the glove box through the Gas Purifier column; oxygen and moisture will start to drop immediately. The button switches the Gas Purifier blower between ON, OFF, and AUTO. ON operates the blower continuously, OFF shuts the blower down, and AUTO turns the blower on and off if an oxygen or moisture monitor control range is desired. If AUTO is chosen, the oxygen or moisture monitor (available from Chapter 7) must be programmed and the monitor automatically controls the blower function.
The oxygen or moisture monitor should be placed inside the glove box for best results. The accessory Oxygen/Moisture Monitor Cable (9-pin) and Electrical 9-pin Sealed Pass-Through must be installed between the monitor (oxygen or moisture) and the Gas Purifier. Please refer to Figure 3-1, Figure 3-8 and Chapter 7 for accessories and connections for AUTO mode control of the sealed circulation blower inside the Gas Purifier.
CAUTION: Some chemicals used in a glove box will
“poison” the copper catalyst inside the Gas Purifier and
reduce the oxygen removal capability. These chemicals
should not be used in the glove box in order to avoid
replacing the copper catalyst and molecular sieve.

Regenerating the Gas Purifier Catalysts
The AtmosPure Re-Gen Gas Purifier is initially shipped with the copper catalyst and molecular sieve fully regenerated and ready to use. The copper catalyst can last 1-3 months with normal use. The performance levels and frequency of regeneration are dependent on several influencing factors including:
Purity of inert gas being used and the amount of O2/H2O removal
by evacuation and filling during initial glove box operation with the inert gas.
Permeation rate of the glove box rubber gloves. Oxygen and moisture content of materials introduced into the
glove box.
Glove box liner material and its permeation rate. Frequency of use and applications that introduce oxygen and
moisture into the inert atmosphere.
The regeneration procedure requires 13 hours and may be done overnight. Refer to Figure 3-7 for control panel features.
WARNING: Before starting the regeneration procedure, make sure that the Gas Purifier exhaust vent is connected, to safely discharge vapors from the regeneration process to the outside or to a fume hood. The exhaust vent is attached to the flow control valve per Figure 3-1.
Regeneration Mode (isolation valves must be closed):
The regeneration process consists of a H2 Set cycle, a Heat cycle, a H2 Purge cycle (using 4% hydrogen/inert gas mixture), and a Vacuum cycle that takes 13 hours and can be done overnight. Moisture is driven from the molecular sieve by the heat. Oxygen is removed from the heated copper catalyst by the hydrogen combining with the copper oxide, which forms H2O. After the heat and purge cycles, the vacuum cycle removes the residual gas and moisture from the purifier. The H2 set cycle allows the operator to set the 4% hydrogen/inert gas mixture flow rate with the flow control valve (Figures 3-1 and 3-7) as follows:
4% hydrogen/ 96% helium, 10 CFH 4% hydrogen/ 96% nitrogen, 20 CFH 4% hydrogen/ 96% argon, 25 CFH

Regeneration Steps: Step 1 – Check to see that the 4% hydrogen/inert gas mixture tank valve is
open and its pressure regulator is set between 10-14 psi. At least ½ a tank of 4% hydrogen/inert gas must be available. Also, be sure that the vacuum pump electrical power cord is plugged in.
Step 2 – Close both isolation valves.
CAUTION: Both isolation valves must remain closed until the entire regeneration cycle is completed and vacuum is released.
Step 3 – Push the automatic START/STOP button on the AtmosPure control
panel (see Figure 3-7) to begin automatic regeneration.
Step 4 Adjust the Hydrogen Purge Flow Rate Knob to provide CFH reading as specified on the back of the Gas Purifier and listed in this instruction manual on the previous page. If proper flow cannot be set within the two minute period, push Start/Stop switch to cancel program. Return to Step 3 when you are ready. Regeneration will begin with the heat cycle after the two minute flow adjustment period. After the 3 hour initial heat cycle, the 2 hour H2 purge cycle will begin automatically.
Step 5 With the vacuum pump on and properly connected, the vacuum pump will run for at least eight hours after completion of the heat and H2 purge cycles.
Step 6 After a minimum 8 hour vacuum cycle, push the START/STOP button to end regeneration.
Step 7 Turn off the vacuum pump then push the VAC. REL. button for one second or less. Note: An optional method releases the vacuum through the inert gas inside the glove box and enhances oxygen removal capacity.
Step 8 Optional Do not push the VAC. REL. button. Instead partially open both isolation valves. The isolation valves must be opened partially to slowly replace the vacuum inside the Gas Purifier with inert gas from the glove box. As the glove box pressure drops due to the Gas Purifier vacuum, refill the glove box with inert gas from the inert gas tank directly or use the Auto Pressure Control of the glove box. Hold the glove box pressure between +1" w.g. to +4" w.g. Once the vacuum is fully released, open the isolation valves 100%. This method fully preserves the regenerated copper catalyst and molecular sieve.

Labconco has engineered the Gas Purifier to meet the ISO 10648-2 Class 1 atmosphere leak specification when used with Labconco controlled atmosphere glove boxes. The information that follows details performance features so you can get the most out of your Gas Purifier. Refer to Figure 4-1.
Gas Purifier Performance Features
1.) Capacity to remove up to 5 liters of oxygen (13,500 ppm) and 660
grams of moisture (18 million ppm) with normal oxygen and moisture permeation rates below 0.16 ppm/min. The adsorption column contains 5 lbs of copper catalyst to remove oxygen and 5 lbs of molecular sieve to remove moisture. Depending on the application and use, the Gas Purifier may operate for 1-3 months before initiating the required 13 hour regeneration process to restore the catalysts.
2.) Ability to reduce oxygen to 1 ppm in less than 2 hours starting
from 1000 ppm. See Appendix D.
3.) Ability to reduce moisture below 15 ppm in 2 hours starting from
1000 ppm. The Gas Purifier can further reduce moisture below 10 ppm in 6 hours, below 5 ppm in 16 hours, below 2-3 ppm in 2 days, and as low as 1 ppm in 3-6 days. See Appendix D.
4.) Internal stainless steel tubing has low permeation rates below 0.10
ppm/min for both oxygen and moisture.
5.) The sealed blower and circulation system assures leak tight
operation for optimized performance.
6.) The Gas Purifier has been tested on all three Labconco glove box liner
materials: stainless steel, fiberglass (FRP), and polyethylene. All three liners meet ISO 10648-2 test methods for oxygen permeation rates below 1.67 ppm/min when tested at -4 inches of water gauge. The lowest attainable oxygen levels are 0.2 ppm for stainless steel, 0.4 ppm for FRP, and 3.5 ppm for polyethylene. The lowest attainable moisture
Product Service 1-800-522-7658
Chapter 4: Features and Safety Precautions
26
levels are 1 ppm for stainless steel, 2 ppm for FRP, and 5 ppm for moisture.
7.) The vacuum pump outlet on the back is rated at 115V, 8A or
230V, 4.5A.
8.) Three solenoid valves control the regeneration of the copper catalyst
and molecular sieve. All are located on the back of the Gas Purifier for easy connection to the 4% hydrogen/inert gas mixture, vacuum pump, and vent exhaust. A flow control valve regulates the 4% hydrogen/inert gas mixture between 10-25 CFH. Two 3/4" diameter isolation valves are closed during the regeneration process, isolating the catalysts from the glove box environment. After the 13 hour regeneration process is complete, the isolation valves are slowly opened up to relieve the vacuum in the column and return the Gas Purifier back to normal circulation mode.
9.) Control Panel features include: a.) Blower button controls the Gas Purifier blower between on, off,
and auto. In the ON position the blower runs continuously, OFF shuts the blower off, and AUTO controls blower with pre­programmed auto mode which can be adjusted using control settings on the Labconco oxygen/moisture monitors. An accessory Oxygen/Moisture Monitor Cable (9-pin) must be used to control the Gas Purifier to high or low limit settings of the oxygen/ moisture monitors.
b.) Flashing indicator lights show proper positioning of the 3/4"
manually operated isolation valves.
c.) Start/Stop Regeneration button starts the programmed 13 hour
regeneration process. The isolation valves must be closed. Indicator lights show each step of the regeneration process. Once the regeneration process is complete, the red indicator light will flash indicating successful program completion. The Start/Stop button is pushed to end the process.
d.) The Vacuum Release button can be used to momentarily release the
vacuum in the purifier column after regeneration is complete. However, Labconco recommends operators should release the column vacuum through the glove box chamber by slowly opening the isolation valves and allowing the auto pressure controller to compensate for the vacuum with inert gas. Set the glove box main chamber pressure between +1" w.g. to +4" w.g. for this preferred method. This method is preferred because it maximizes the capacity of the Gas Purifier and does not allow atmospheric air to deplete the Gas Purifier column. Note: Atmospheric air contains
21% oxygen (210,000 ppm). 40% relative humidity air contains 11,250 ppm moisture.
e.) Main power switch turns the inlet power to the Gas Purifier on
and off.
10.) The optimized regeneration process is completed in 13 hours and may be completed overnight while unattended.
Product Service 1-800-522-7658
Chapter 4: Features and Safety Precautions
27
11.) The Gas Purifier automatically compensates for power outages and
restarts the regeneration process if interrupted for 10 minutes or longer. This feature assures complete regeneration of the copper catalyst and molecular sieve as the system would cool and not regenerate properly.
12.) Leak tight. Each Gas Purifier has been factory tested with a helium
mass spectrometer and found to have no detectable leaks greater than 1 x 10-6 cc/sec.
13.) Each Gas Purifier ships fully regenerated and is ready to use. The
Gas Purifier has the capacity to remove 13,500 ppm oxygen and 18 million ppm moisture.
14.) The Gas Purifier may be programmed by selecting auto mode and
connecting it to an accessory oxygen or moisture monitor. The back of the Gas Purifier has an Auto Mode Moisture/Oxygen Connector (9-pin) for connection to the oxygen or moisture monitor relays. Refer to Labconco accessories for oxygen monitors, moisture monitors, and the Oxygen/Moisture Monitor Cable (9-pin).
15.) The Gas Purifier inlet/outlet connections are 3/4" compression
fittings. Connection accessory kits are available with either neoprene lined flexible hose or hard plumbed stainless steel tubing. All glove boxes were tested with the neoprene lined hose. An accessory 3/4" to 3/8" adapter kit is also available for connection to polyethylene glove boxes and pre-2011 fiberglass/stainless steel glove boxes.
16.) The Gas Purifier’s compact design easily rests beneath the glove box
on Labconco’s base stands. Dimensions are 14.9"W x 21.9"H x
31.8"D.
17.) The Gas Purifier can be connected to one vacuum pump, shared
with the glove box and powered by the glove box vacuum pump outlet receptacle. A controlled atmosphere communications port (C.A. COM 6-pin) on the back of the Gas Purifier allows for shared access of the vacuum pump when used with Controlled Atmosphere glove boxes with Auto Pressure Control. A separate accessory C.A. COM. Cable with 6-pin connectors is available for communication between the Gas Purifier and the Auto Pressure Controller of the glove box. The cable must be used to share the one vacuum pump.

Now that the installation of your Gas Purifier and glove box is completed, you are ready to use it.
Read this chapter to learn about:
Routine Daily Work Procedures. Hazardous Use with Chemicals. Prohibited Materials Use.
Routine Daily Work Procedures
Planning
Thoroughly understand procedures and equipment required before
beginning work. Work from a written plan.
Consult your Safety Officer for personal protective equipment
recommendations and operating pressure confirmation.
Start-up
Basic start-up procedure includes: turning on the vacuum pump,
opening the inert gas valve on the gas supply tank, turning on the glove box light and turning on the blower to the Gas Purifier once an inert atmosphere below 5000 ppm is established.
Loading Materials and Gas Purifier Set-Up
Load only the materials and equipment required for the procedure.
Do not overload the glove box. When loading, ensure the inner door is closed before opening the outer door. Then close the outer door.
Product Service 1-800-522-7658
Chapter 5: Using Your Gas Purifier
32
Perform evacuation and fill cycle on the transfer chamber of the glove
box using the vacuum outlet and gas inlet valves. Depending on the vacuum level achieved, it takes 1-5 cycles to reduce oxygen and moisture levels below 1%. Porous materials being transferred may require longer sustained vacuum evacuations to remove the oxygen and moisture trapped in the materials.
In order to achieve the lowest oxygen and moisture levels in a glove
box, perform the required evacuation and fill cycles on the main chamber using the vacuum outlet and gas inlet valves. To automate the evacuation and fill cycles (1-499) for both glove box chambers, the addition of the Automatic Pressure Controller (5238600 or
5238601) is recommended (see Chapter 7) or use a Protector Controlled Atmosphere Glove Box with Auto Pressure Control. Normally 75-100 evacuation and fill cycles will reduce moisture and oxygen levels below 1%. An additional 100 cycles will reduce moisture and oxygen levels below 0.3% or 3,000 ppm. The AtmosPure Gas Purifier blower can now be turned on. The use of
external glove port covers will expedite the evacuation and fill cycle time and help maintain low moisture and oxygen levels when the glove box is not in use.
Maintaining a -1" to +1" water gauge pressure difference can help to
preserve the glove box atmosphere.
The AtmosPure Re-Gen Gas Purifier is required to maintain oxygen
and moisture levels below 0.3%-0.5%. Turn the Gas Purifier blower on to start circulation and reduce oxygen and moisture. Labconco
AtmosPure Re-Gen Gas Purifiers can maintain oxygen levels below 1 ppm and moisture levels below 1 ppm depending on liner material and applications.
Monitoring moisture and oxygen levels inside the glove box is
recommended by using accessory monitors (see Chapter 7).
The Gas Purifier catalysts will last for 1-3 months before requiring
regeneration. See Chapter 3 for instructions to start regeneration.
Work Techniques
Maintain work at a slightly negative pressure if working with
hazardous compounds.
Continuously run the Gas Purifier blower to preserve the inert
atmosphere if so desired.
Product Service 1-800-522-7658
Chapter 5: Using Your Gas Purifier
33
Transferring Materials to the Outside
All open chemical weigh vessels or containers must be sealed before
removing materials from the glove box main chamber.
Objects in contact with previously contaminated internal atmospheres
must be surface decontaminated or bagged before removal from the glove box through the transfer chamber.
After placing materials to be removed in the transfer chamber and
locking the internal door, the transfer chamber must be evacuated and filled approximately 1-5 times depending on vacuum level achieved. This ensures the removal of any remaining airborne contaminants before the outer door is opened. Never apply a high vacuum purge below 2" mercury pressure on sensitive electronic moisture and oxygen monitors. The exact number of cycles should be determined by your Safety Officer.
Shutdown
To help preserve the controlled atmosphere, leave the glove box main
chamber under -1" to +1" water gauge pressure and continuously run the Gas Purifier blower. The use of the accessory external glove port covers can assist in preserving the inert atmosphere by reducing permeation through the gloves.
Keep the outer door closed when not in use.
Hazardous Use with Chemicals
Hazardous chemicals may be used safely only when the glove box vacuum pump is properly vented and/or filtered to the outside. Consult
your Safety Officer for proper venting and filtering of the vacuum pump exhaust.
Prohibited Materials Use
Due to stainless steel components, the Gas Purifier and glove box interior must not be exposed to mineral acid. The Gas Purifier and glove box life spans will be limited with use of mineral acids. Additionally, materials referenced in Chapter 3 cannot be used (such as alcohols, halides, halogens, hydrazine, heavy metals, mercury, arsine, phosphene, and sulfur containing compounds) because they will poison the Gas Purifier catalysts and reduce their effectivity and lifespan.
NOTE: Should the catalysts inside the Gas Purifier become ineffective after two regeneration cycles, the two catalysts can be replaced. See Chapter 6: Maintenance and Appendix A: Replacement Parts for replacement.

This Appendix contains technical information about all the Gas Purifiers including electrical specifications and environmental operating conditions.
10 Amps, 100-115V or 5 Amps, 230V, 50/60 Hz AtmosPure Re-Gen
Gas Purifier.
Environmental Conditions
Indoor use only. Maximum altitude: 12,000 feet (3,657 meters). Ambient temperature range: 41° to 104°F (5° to 40°C). Maximum relative humidity: 80% for temperatures up to 88°F (31°C),
decreasing linearly to 50% relative humidity at 104°F (40°C).
Main supply voltage fluctuations not to exceed ±10% of the nominal
voltage.
Transient over-voltages according to Installation Categories II (Over-
voltage Categories per IEC 1010). Temporary voltage spikes on the AC input line that may be as high as 1500V for 100-115V models and 2500V for 230V models are allowed.
Used in an environment of Pollution degrees 2 (i.e., where normally
only non-conductive atmospheres are present). Occasionally, however, a temporary conductivity caused by condensation must be expected, in accordance with IEC 664.
