Safety Instructions
To maximize user safety and ensure corr ect device operation, all instructions con-
tained in this section should be read carefully.
Before Applying Power
Verify that the line voltage is 115 to 230 VAC, single phase.
Ground the Exciter
Caution: It is important that the user observeall warnings and instructions that
are on the device and contained in this manual.
Warning: DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Operation of the transmitter in the presen ce of flammable gass es or fumes can
endanger persons proximate to the site of operation.
Caution: NO NOT REMOVE THE TRANSMITTER’S COVER
Removal of the exciter cover will invalidate the Warranty.
Component replacement and internal adjustments must be
made only by CW Broadcast 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 interr uption 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 (nor-
mal blow, time delay, etc.) should be use d. Do not use repaired fuses or short-cir-
cuited fuseholders. To do so could cause a shock or fire hazard.
Output Connector
Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electric ity can destroy static -sensitive devices
or micro-circuitry. Proper packaging and grounding t echniques are necessary pre-
cautions to prevent damage. Always take industry-standard precautions.
Grounding Methods
Guard against electrostatic damage at workstations by following these steps:
1. Cover workstations with approved anti-static material. Provide a wrist strap connect-
ed to a work surface and properly grounded tools and equipment.
2. Use anti-static mats, heel straps, or air ionizers to give added protection.
3. Handle electrostatic-sensitive components, boards, and assemblies by the case or the
PCB edge.
4. Avoid contact with pins, leads, or circuitry.
5. Turn off power and input si gnals before inserting and removing connectors or test
equipment.
6. Keep the work area free of non-conductive materials such as ordinary plastic assem-
bly aids and Styrofoam.
7. Use field service tools, such as cutters, screwdrivers, and vacuums that are conduc-
tive.
Warning: The type-N output connector carries dangerously high RF voltages
that present shock and burn hazards. Never operate the transmitter with-
out properly terminating the output connector in either an adequately rated load
or antenna.
General Safety Rules
•The device must be used in acco rdance with the instructions for use.
•Electrical installations in the room must co rrespond to the requirements of respective regu-
lations.
•Take care that there are no cabl es, particularly mains cables, in areas where persons can trip
over them.
•Do not use a mains connection in sockets shar ed 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 pow er source only when the power cord is dis-
connected 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 h eat sources or in a da mp 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 FM 500ES, the device must be shut
down and secured against unintentional operation.
•Repairs may only be carried out by a person authorized by CircuitWerkes, Inc..
•If extensions are made to the transmitter, the le gal stipulations and the device specifications
must be observed.
•The transmitter must be switched off and the line cord disconnected from the AC source
when removing the top cover.
