Electrical Safety
G:BOX Systems are designed to protect the user from potential electrical hazards. This section
describes some recommended electrical safety practices.
WARNING
Lethal voltages are present at certain points within the instrument.
When the instrument is connected to mains power, removing the instrument
covers is likely to expose live parts.
Even when the power switch is off, high voltages can still be present –capacitors
within the instrument may still be charged even if the instrument has been
disconnected from all live voltage sources.
The G:BOX System must be correctly connected to a suitable electrical supply. The supply must have
a correctly installed protective conductor (earth or ground) and must be installed and checked by a
qualified electrician before connecting the instrument.
WARNING
Any interruption of the protective conductor inside or outside the G:BOX System,
or disconnection of the protective conductor terminal is likely to make the
instrument dangerous.
Intentional interruption of the protective conductor is prohibited.
WARNING
Ensure that the mains supply socket on the instrument is not obstructed, i.e. leave
a gap to allow easy disconnection of the mains cord.
WARNING
If the mains power cord has to be replaced, ensure that the replacement cord is
appropriately rated and approved for the intended use.
When working with the G:BOX System:
Connect the instrument to a correctly installed mains power outlet that has a protective
conductor connection.
Do not operate the instrument with any covers or internal parts removed.
Do not attempt to make internal adjustments or replacements except as directed in the
G:BOX System documentation.
Disconnect the instrument from all live voltage sources before opening it to make any
adjustments, replacements, maintenance or repair. If the opened instrument must be
operated for further adjustment, maintenance or repair, this must only be done by a
supplier’s Service Engineer.

Safety - 4 G:BOX Service Manual
If it is possible that the instrument is no longer electrically safe for use, make the
instrument inoperative and secure it against any unauthorised or unintentional operation.
The electrical safety of the instrument is likely to be impaired if:
It has any signs of visible damage.
If it has been subjected to prolonged storage in unfavourable conditions.
If it has been subjected to severe stress during transportation.
Changing a Fuse
There are two User accessible fuses that may need to be replaced:
These are located in the mains power socket on the rear panel of the G:BOX instrument and
are only accessible when the mains power cord has been removed.
To change the fuses:
WARNING
Switch off the instrument and unplug the mains power cord from the electrical
supply.
Gently pull out the fuse holder.
Replace the fuses with new fuses of the same type and rating. The fuse type is 20 mm x 5
mm IEC127 T 6.3 A H 250V for instruments in all countries.
Replace the fuse holder.
Note: Accessories such as the Transilluminator may have their own fuse.
Note: If the instrument still does not work correctly after replacing the fuses with the correct
replacements, or if the fuses blow repeatedly, contact the supplier’s Office or
Representative.
Electrical Protection
Insulation: Class I rating for external circuits. Only connect equipment that meets the
requirements of IEC 61010-1, IEC 60950 or equivalent standards.
Installation Category: The instruments are able to withstand transient overvoltages typically
present on the mains supply. The normal level of transient overvoltages is impulse
withstand (overvoltage) category II of IEC 60364-4-443.
Pollution Degree 2: Normally only non-conductive pollution occurs. Occasionally, however,
temporary conductivity caused by condensation must be expected.

before altering, or making any new electrical connections.
Safety Information for Service Personnel
The following section presents safety information with which you need to be familiar before you
service a G:BOX System.
General Safety
Follow these rules to ensure general safety:
Observe good housekeeping in the area of the instrument during and after maintenance.
When lifting any heavy object:
1. Make sure that you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.
4. Lift by standing or by pushing up with your leg muscles; this action removes the
strain from the muscles in your back. Do not attempt to lift any object that weighs
more than 16 kg (35 lb) or that you think is too heavy for you.
Do not perform any action that causes hazards to the customer’s personnel, or that makes
the instrument unsafe.
Before you start the instrument, make sure that other service representatives and the
customer’s personnel are not in a hazardous position.

Safety - 6 G:BOX Service Manual
Place removed covers and other parts in a safe place, away from all personnel, while you
are servicing the instrument.
Keep your toolcase away from walk areas so that other people will not trip over it.
Do not wear loose clothing that can be trapped in the moving parts of an instrument. Make
sure that your sleeves are fastened or rolled up above your elbows. If your hair is long,
fasten it back.
Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip,
about 8 centimeters (3 inches) from the end.
Do not wear jewelry, chains, metal-framed eyeglasses, or metal fasteners for your clothing.
Metal objects are good electrical conductors.
Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching
springs, using solvents, or working in any other conditions that might be hazardous to your
eyes.
After service, reinstall all safety shields, guards, labels, and ground wires. Replace any
safety device that is worn or defective.
Reinstall all covers correctly before returning the instrument to the customer.
Louvers on the instrument help to prevent overheating of internal components. Do not
obstruct fan louvers or cover them with labels or stickers.
Electrical Safety
Follow these rules to ensure electrical safety:
Use only approved tools and test equipment. Some hand tools have handles covered with a
soft material that does not insulate you when working with live electrical currents.
Many customers have, near their equipment, rubber floor mats that contain small
conductive fibers to decrease electrostatic discharges. Do not use this type of mat to
protect yourself from electrical shock.
Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet.
If an electrical accident occurs, you can then operate the switch or unplug the power cord
quickly.
Do not work alone under hazardous conditions or near equipment that has hazardous
voltages.
Disconnect all power before:
-Performing a mechanical inspection.
-Working near power supplies.
-Removing or installing mains units.
Before you start to work on the instrument, unplug the power cord. If you cannot unplug it,
ask the customer to power-off the wall box that supplies power to the instrument, and to
lock the wall box in the off position.

G:BOX Service Manual Safety - 7
If you need to work on an instrument that has exposed electrical circuits, observe the
following precautions:
-Ensure that another person, familiar with the power-off controls, is near you.
-Use only one hand when working with powered-on electrical equipment; keep the other
hand in your pocket or behind your back.
Note: An electric shock can occur only when there is a complete circuit. By observing the above
rules, you may prevent a current from passing through your body.
-When using testers, set the controls correctly and use the approved probe leads and
accessories for that tester.
-Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from
grounds such as metal floor strips and machine frames.
Regularly inspect and maintain your electrical hand tools for safe operational condition.
Do not use worn or broken tools and testers.
Never assume that power has been disconnected from a circuit. Always check that it has
been powered off.
Always look carefully for possible hazards in your work area. Examples of these hazards are
moist floors, nongrounded power extension cables, power surges, and missing safety
grounds.
Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The
surface is conductive; such touching can cause personal injury and instrument damage.
If an electrical accident occurs:
-Use caution; do not become a victim yourself.
-Switch off power.
-Send another person to get medical aid.
Sensitivity to Electrostatic Discharge
Any instrument part containing transistors or integrated circuits (ICs) should be considered sensitive
to electrostatic discharge (ESD.) ESD damage can occur when there is a difference in charge between
objects. Protect against ESD damage by equalizing the charge so that the instrument, the part, the
work mat, and the person handling the part are all at the same charge.
When handling ESD-sensitive parts:
Keep the parts in protective packages until they are inserted into the product.
Avoid contact with other people.
Wear a grounded wrist strap against your skin to eliminate static on your body.
Prevent the part from touching your clothing. Most clothing is insulative and retains a
charge even when you are wearing a wrist strap.
Use the black side of a grounded work mat to provide a static-free work surface. The mat is
especially useful when handling ESD-sensitive devices.

Safety - 8 G:BOX Service Manual
Select a grounding system, such as those listed below, to provide protection:
-Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.
-When working on a double-insulated system, use an ESD common ground or reference
point. You can use coax or connector-outside shells on these systems.
-Use the ground prong of the ac plug on ac-operated computers.
