Safety InstructionsTo maximize user safety and ensure correct device operation, all instructions con-tained in this section should be read carefully.Before Applying PowerVerify that the line voltage is 115VAC.Ground the ExciterCaution: It is important that the user observe all warnings and instructions thatare on the device and contained in this manual.Warning: DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHEREOperation of the FM500ES in the presence of flammable gass es or fumes canendanger persons proximate to the site of operation.Caution: NO NOT REMOVE THE EXCITER COVERRemoval of the exciter cover will invalidate the Warranty.Component replacement and internal adjustments must bemade only by PTEK qualified service personnel.To minimize shock hazard, the exciter chassis must be connected to an electricalground, 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 (safetyground) at the power outlet. Any interr uption of the protective (grounding)conductor or disconnection of the protective earth terminal will cause a potentialshock hazard that could result in personal injury. If the exciter is to be energized byany other source be certain that the chassis is connected to a separate safety ground.ES Series Operating Manual and User GuidePTEKTM
FusesOnly 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 ConnectorElectrostatic Discharge (ESD)A sudden discharge of electrostatic electricity can destroy static-sensitive devicesor micro-circuitry. Proper packaging and grounding techniques are necessary pre-cautions to prevent damage. Always take industry-standard precautions.Grounding MethodsGuard 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 thePCB edge.4. Avoid contact with pins, leads, or circuitry.5. Turn off power and input signals before inserting and removing connectors or testequipment.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 voltagesthat present shock and burn hazards. Never operate the exciter with-out properly terminating the output connector in either an adequately rated loador antenna.ES Series Operating Manual and User GuidePTEKTM

BRack-Mount Slide InstallationAn optional set of two rack-mount slides (left side and right side) is available for allFM500ES FM Stereo Broadcast Transmittersystems, and should be ordered at thetime of purchase. The FM500ES chassis contains two (2) threaded screw holes (seeFigure B-1 on page B-2) on each side to accommodate #10-32 size screws (includedwith the rack-mount slide kit).Dimensions of the screw-hole patterns on the sides of the FM500ES chassis forinstalling rack-mount slides are shown in Figure B-2 on page B-3. The requiredholes for specialized steel or aluminum slides will have to be measured, drilled, andtapped before installation.The rack-mount slide installation kit includes the following items:a. Two inside slide sectionsb. Two outside slide sectionsc. Two front (short) slide bracketsd. Two rear (long) slide bracketse. Assorted screws, washers, and nutsFollow these steps to install a steel rack-mount slide to the FM500ES chassis:Caution: Any screws used to mount a slide to a FM500ES chassis must not exceeda length of 3/8” to prevent excessive penetration of the chassis.AppendixES Series Operating Manual and User GuidePTEKTM
1. Attach the inside slide section (see Figure B-3 on page B-3) to both sides ofthe FM500ES chassis using two #10-32 screws per side (see .2. Measure the depth of the 19” equipment rack into which the FM500ES systemwill be installed (this can vary from 24” to 30”).3. Using the depth of the equipment rack, adjust and attach the front and rearslide brackets to the outside slide section using the screws, washers, and nutsprovided with the slide kit.4. With all slide brackets securely attached to both the right and left outside slidesections, install both sections to the inside right and inside left of a 19” rackwith two bolts per bracket, making sure there is adequate room for the 2RUheight (3.5”) of a FM500ES system.5. Carefully insert the FM500ES system into the 19” rack so that the insideslides on both sides of the chassis travel smoothly into the channels of the out-side slide sections. Push the system into the rack until the mounting bracketson the front of the chassis are flush with the front of the rack.6. Secure the FM500ES system to the 19” rack with two bolts on each side.Figure B-1.
