3.3.4 Safety Guidelines During Surge Testing
• Do not work alone.
• Do not use the equipment in conditions other than reasonable laboratory conditions. There
should be no condensing humidity or water standing on the floor or work surfaces; there
should not be significant dust or other contamination.
• Ensure that no one is touching the equipment under test (EUT) during the test or
immediately after the test until AC power to the EUT has been turned off.
• Ensure that there is a barrier to act as protection in case the equipment under test
explodes. The barrier should be interlocked to prevent surging and to disconnect all AC if
the barrier is removed.
• The equipment under test must be surrounded by sufficient insulating material to withstand
twice the surge voltage. Consider distance to the floor or table and walls if air is the
insulating material.
• Ensure that the proper supply mains voltages are applied to both Com-Power equipment
and to the equipment under test, and that the AC branch circuit is capable of supplying
the current.
• The ground (protective earth), neutral and phase lines of the AC supply to the equipment
under test (EUT) and Com-Power equipment must be connected properly. Do not defeat
the protective earth connection.
• When surging a powered EUT, the mains supply to the equipment under test must be
capable of handling the potential AC fault current (e.g. do not use a UPS to power the
EUT).
• Never surge an AC mains line other than through the EUT output connector or compatible
Com-Power single-phase or three-phase coupler.
• Use only equipment which is designed to be safe for the test being performed.
• Do not test in a potentially explosive atmosphere (e.g. where there are gas fumes).
• Never use equipment that is operating in a strange manner, or that shows clear indication
of abuse.
• If probes are in use, be sure they are differential probes which have no ground connection
to the surged ground or to the equipment under test.
3.3.5 Safety Concerns During Surge Testing
Surge testing is hazardous. The equipment under test (EUT) can ignite, possibly explosively.
Noxious, toxic and sometimes fatal fumes can be generated by the burning equipment.
Accumulated gases may ignite explosively (i.e., flashover).
In an environment where surge testing takes place, it is absolutely crucial that these
minimum safety precautions be taken:
• Surge testing should be performed only by properly trained test personnel who are
experienced in conducting such tests, or be observed and supervised by such
experienced personnel. No person subject to heart or neurological conditions should be
allowed to conduct surge tests. Persons with pacemakers should not be allowed in or near
the area where testing is conducted.
• Never leave a procedure or a test setup unattended.
• All personnel working in the area must be shielded with appropriate eye protection, body
protection and electrical protection. They should not be allowed to work in a direct line of
a possible explosion of the equipment under test.
• The test area should be a clear and unobstructed environment dedicated to such tests.
• The test area should be equipped with ventilating hoods and blowers to remove gases hat
may be caused by exploding or burning components.
• The test area should have nonflammable walls and floors plus shielding to contain
exploding parts and flames.
• There must be fire extinguishers certified for use in electrical and chemical fires readily
available at the test site. DO NOT USE WATER TO EXTINGUISH AN ELECTRICAL FIRE.
• All flammable materials and debris must be outside the test area, and the area must be
well marked, preferably by physical barriers, to prevent accidental intervention by non-test
personnel while a test is in progress.

When the SGTEL-168 is NOT under software control, the EUT
power state is controlled via the front and rear panel EUT
POWER switches. If the EUT power input port is connected to an
active source, power is available at the EUT POWER OUTPUT
port when both the rear panel and front panel switches are
turned on.
The SGTEL-168 surge generator will automatically check the EUT
power status at the start of any test or test sequence which
includes surges applied to its internal CDN output terminals.
If the EUT power is not enabled on the SGTEL-168 front panel,
the following message will be displayed:
If the SGTEL-168 uses an power frequency phase detection
circuit to determine whether AC power is present at the EUT
power port. If AC power is not detected, and EUT power is
enabled on the front panel, the following message will be
displayed:
If it is your intention to run the test without the presence of AC
power, as would typically be the case during waveform
verification, for instance; choose the CONTINUE option by
pressing the button, and the test will begin.
Otherwise, choose the ABORT option by pressing the button
to abort the test. After correcting the problem, restart the test.

4.1.2.2 Turning ON/OFF EUT Power – REMOTE Control
When the SGTEL-168 is under remote control using the
TransWare™ software, the EUT power state is controlled via the
front and rear panel EUT POWER switches, in addition to the EUT
POWER function located on the Control Panel within the
TransWare™ software. When the SGTEL-168 front panel EUT
POWER switch is turned on, the EUT power status in the
TransWare™ Control Panel will change from “OFF” to “READY”.
At this point, the EUT power output can be turned on by
pressing the TransWare™ EUT POWER button.
The SGTEL-168 surge generator will automatically check the EUT
power status at the start of any test or test sequence which
includes surges applied to its internal CDN output terminals.
If the EUT power is not enabled on the SGTEL-168 front panel,
the following message will be displayed:
If the SGTEL-168 uses an power frequency phase detection
circuit to determine whether AC power is present at the EUT
power port. If AC power is not detected, and EUT power is
enabled on the front panel, the following message will be

power, as would typically be the case during waveform
verification, for instance; choose the CONTINUE option by
pressing the button, and the test will begin.
Otherwise, choose the ABORT option by pressing the button

4.2 Input/Output Ports
4.2.1 Safety Interlock Port
The safety interlock port (left) can (optionally) be
used to disable the surge generator output for
safety reasons using an external switch, such as the
door contacts of the test chamber, for instance. In
cases where no interlock switch is used, simply
connect the safety interlock key (right) to this port
to enable the generator.
For those cases where use of an external switch as the safety interlock is
desired, simply wire your switch contacts to pins 2 and 3 of the supplied,
spare 7mm push-pull connector as shown in Figure 6. Remove the
interlock key from the SGTEL-168 interlock port, and plug in the switch
assembly, and the generator will now be enabled/disabled with the
opening/closing of the switch contacts.

4.2.2 Fiber Optic Port
The SGTEL-168 surge generator can optionally be
remotely controlled by a computer via the fiber optic
remote interface, using Com-Power’s TransWare™
software.
4.2.2.1 Setting up the Remote Interface
As shown in Figure 7, connect the supplied fiber optic cable
into the fiber optic port on the front of the SGTEL-168. Connect
the opposite end of the fiber optic cable into the powered
OTA-232 Optical Transreceiver Adapter. Finally, connect the
OTA-232 Adapter to a computer with the Com-Power
TransWare™ software installed.

4.2 Monitor Ports
The monitor ports provide a convenient method for
verification various surge waveform parameters, and
triggering of oscilloscope measurements.
4.3.1 Sync Output Port (Sync. O/P)
The SYNC OUTPUT port is provided as an alternative method of
triggering the oscilloscope measurement. The SYNC OUTPUT port
connects directly to the external trigger input of any
oscilloscope. The output is 5 VDC steady state, and drops to
zero volts for a period of 20 ms when the surge generator output is
discharged.
4.3.2 Voltage Monitor Port (Vmon)
The Voltage Monitor Port (Vmon) is intended to be connected to
a high impedance (>10kΩ) input of an oscilloscope for
verification of peak surge voltage for all waveforms. The output
scaling is 1V / 1000V (1000:1 ratio).
This port provides a convenient method by which the open circuit* surge
output voltage can be verified. The peak output voltage measured at
this port is representative of the voltage at the surge output terminals with
a typical accuracy within ±10%.
However, the actual wave shape of the surge waveform may become
distorted; and therefore this port should not be used for measurement of
other parameters, such as rise time or decay time. These parameters must
be measured at the surge output terminals.
4.3.3 Current Monitor Port (Imon)
The Current Monitor Port (Imon) is intended to be
connected to a high impedance (>10kΩ) input of an
oscilloscope for verification of peak surge current for all
waveforms. The output scaling is 1V / 100V (100:1 ratio).
This port provides a convenient method by which the short circuit* surge
output current, rise and decay time can be verified. The waveform
parameters measured at this port are representative of those at the surge
output terminals, with a typical accuracy within ±10%.
*
Measurements at these ports are within the stated accuracy for open circuit voltage
measurements and short circuit current measurements. Open circuit measurements are
performed with no external connections to the surge output terminals; while short circuit
current measurements are performed with the surge output terminals short circuited.
Measured values will vary with alternate terminations (with the EUT connected, for instance).
