An electrical power source must be within 2 m (7 ft) of the system. Power supplied to the system should be from dedicated, uninterrupted sources. Power must be free of voltage dropouts, transient spikes, frequency shifts, and other line disturbances that impair reliable performance. Each wall outlet you use must be equipped with a 3-wire line: live, neutral, and ground.
If you suspect power quality problems at your site, or if your system will be installed in a heavy industrial environment, we recommend a power quality audit before installation. Contact us or your local electrical authority for more information.
Avoid shock hazard.
To assure a good ground connection and avoid shock hazard, do not use an outlet that is connected to a conduit ground. The ground must be a non-current-carrying wire connected to earth ground at the main distribution box.
Note Some accessories require their own separate power connections.
Note Your instrument was specially designed to meet the requirements of standard IEC 61000-4-4.
Power line conditioning accessories
Uninterruptible power supplies (UPS) are available from us. A UPS reduces the probability of a system shutdown if power is lost elsewhere in the building. Power line conditioners (which ensure that your service is free from sags, surges or other line disturbances) also are available in the U.S.A. from us for 120-volt operation. Line conditioners for 220-volt operation can be purchased locally. Contact technical support for information about power conditioners and UPS.
Electrical service specifications
The following table lists the specifications for electrical service. Contact our service representative in your area if you have questions about the requirements. If you are not sure that
your power lines meet these requirements, contact technical support for information about power audits.
|Input current||3.2 A|
|Input voltage||100 to 240 VAC|
|Line frequency||47 to 63 Hz|
|Line disturbances||Sags, surges or other line disturbances must not exceed 10% of input voltage (even for a half cycle).|
|Noise||less than 2 V (common mode)
less than 20 V (normal mode)
Generally, 50% more power should be available than the entire system (including accessories) typically uses. Maximum power consumption and heat dissipation specifications for the
microscope and accessories are shown below. The values are approximate.
|Item||Power Consumption||Max. Heat Dissipation|
|FTIR Microscope||130 W||443 Btu/hr|
|Standard computer and monitor*||460 W||1,570 Btu/hr|
|* Values shown are estimates. See the power specifications on the rear panels or undersides of these units.|
Each wall outlet you use must be equipped with a 3-wire line: live, neutral, and ground. The ground must be a non-current carrying wire connected to earth ground at the main distribution box. To assure a good ground connection and avoid shock hazard, do not use an outlet that has ground connected to a conduit ground.
Be sure to use an appropriate power cord for the electrical service. The power cord supplied with accessories is a 3-wire, grounded power cord, appropriate for use in the country listed as the shipping destination for the microscope. To prevent electrical hazards, do not remove or defeat the ground prong on the power cord. If you use an extension cord, it must have a protective conductor.
If the power cord becomes damaged, replace it. Contact us if you need additional information about replacement cord or extension cord specifications.
