Safety Instructions
To maximize user safety and ensure correct device operation, all instructions contained in
this section should be read carefully.
Caution: It is important that the user observe all warnings and instructions
that are on the unit and contained in this manual.
Before Applying Power
Warning: DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Operation of the ES Series in the presence of flammable gases or fumes
can endanger persons proximate to the site of operation.
Verify that the line voltage is 115VAC (220VAC for the FM1050ES).
Ground the Exciter
Caution: DO NOT REMOVE THE EXCITER COVER
Removal of the exciter cover will invalidate the warranty. Component
replacement and internal adjustments must be made only by PTEK
qualified service personnel.
To minimize shock hazard, the exciter chassis must be connected to an electrical ground,
the exciter must be connected to the AC power mains through a three-conductor power
cable, with the third wire connected to an electrical ground (safety ground) at the power
outlet. Any interruption of the protective (grounding) conductor or disconnection of the
protective earth terminal will cause a potential shock hazard that could result in personal
injury. If the exciter is to be energized by any other source be certain that the chassis is
connected to a separate safety ground.

Fuses
Only fuses with the same required current, voltage rating, and specified type (normal
blow, time delay, etc.) should be used. Do not use repaired fuses or short-circuited fuse
holders. To do so could cause a shock or fire hazard.
Output Connector
Warning: The type-N output connector carries dangerously high RF
voltages that present shock and burn hazards. Never operate the exciter
without properly terminating the output connector in either an adequately
rated load or antenna.
Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices or
micro-circuitry. Proper packaging and grounding techniques are necessary precautions to
prevent damage. Always take industry-standard precautions.
Grounding Methods
The single point or star grounding system is recommended. There is one common or star point
where all grounds join together at a single point. This point is often a selected point along a
ground system that encircles the building using copper strap and multiple ground rods not closer
than ten feet. Usually four ground rods connected with four inch copper strap spaced around the
tower will be required. Wide flat copper strap should be used to reduce the ground conductor
inductance.
The interior of the building should have a common ground system made up of 2 or 4 inch copper
ground strap, which should be tied to the outside star point. The AC mains ground should also be
connected to the star point. All coaxial cables should enter and exit the building at a single entry
point and their shield(s) should be connected to the ground plate.
A single connection point to the station reference ground should be established, preferably where
the AC power wiring and the RF feed coaxial cable enter the transmitter building. The purpose
of this ground is to prevent ground loops and to ensure unwanted currents do not flow into the
transmitter cabinet. The shield of the RF feed cable, the AC power, the ground return for the AC
suppression system and the transmitter’s reference ground point should all be individually
connected to this point by insulated, low inductance, low impedance ground straps.

General Safety Rules
The device must be used in accordance with the instructions for use.
Electrical installations in the room must correspond to the requirements of respective
regulations.
Take care that there are no cables, particularly mains cables, in areas where persons can
trip over them.
Do not use a mains connection in sockets shared by a number of other power consumers.
Do not use an extension cable.
Only use the mains cable supplied.
The unit is completely disconnected from the power source only when the power cord is
disconnected from the power source. Therefore, the power cord and its connectors must
always remain easily accessible.
Do not set up the device in the proximity of heat sources or in a damp location. Make
sure the device has adequate ventilation.
All plugs on the connection cables must be screwed or locked to the chassis housing.
The device is designed to be used in horizontal position only.
The device is no longer safe to operate when the device has visible damage or the device
no longer functions.
In case of system malfunction or visible damage to the ES Series, the device must be shut
down and secured against unintentional operation.
Repairs may only be carried out by authorized PTEK personnel.
If extensions are made to the ES Series, the legal stipulations and the device
specifications must be observed.
The ES Series must be switched off and the line cord disconnected from the AC source
when removing the top cover.
