PTEK Customer Service Manager 1723 Little Orchard Street—Unit D San Jose, CA 95125 (408) 448-3342 PTEK TM ES Series Operating Manual and User Guide 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 device and contained in this manual. Before Applying Power Warning: DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE Operation of the FM500ES in the presence of flammable gass es or fumes can endanger persons proximate to the site of operation. Verify that the line voltage is 115VAC. Ground the Exciter Caution: NO 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 threeconductor 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. PTEK TM ES Series Operating Manual and User Guide Fuses Only fuses with the same required current, voltage rating, and specified type (normal blow, time delay, etc.) should be use d. Do not use repaired fuses or short-circuited fuseholders. 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 Guard against electrostatic damage at workstations by following these steps: 1. Cover workstations with approved anti-static material. Provide a wrist strap connected 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 signals before inserting and removing connectors or test equipment. 6. Keep the work area free of non-conductive materials such as ordinary plastic assembly aids and Styrofoam. 7. Use field service tools, such as cutters, screwdrivers, and vacuums that are conductive.

The FM500ES chassis contains two (2) threaded screw holes (see Figure B-1 on page B-2) on each side to accommodate #10-32 size screws (included with the rack-mount slide kit). Dimensions of the screw-hole patterns on the sides of the FM500ES chassis for installing rack-mount slides are shown in Figure B-2 on page B-3. The required holes for specialized steel or aluminum slides will have to be measured, drilled, and tapped before installation. Caution: Any screws used to mount a slide to a FM500ES chassis must not exceed a length of 3/8” to prevent excessive penetration of the chassis. The rack-mount slide installation kit includes the following items: a. Two inside slide sections b. Two outside slide sections c. Two front (short) slide brackets d. Two rear (long) slide brackets e. Assorted screws, washers, and nuts Follow these steps to install a steel rack-mount slide to the FM500ES chassis: PTEK TM ES Series Operating Manual and User Guide 1. Attach the inside slide section (see Figure B-3 on page B-3) to both sides of the FM500ES chassis using two #10-32 screws per side (see . 2. Measure the depth of the 19” equipment rack into which the FM500ES system will be installed (this can vary from 24” to 30”). 3. Using the depth of the equipment rack, adjust and attach the front and rear slide brackets to the outside slide section using the screws, washers, and nuts provided with the slide kit. 4. With all slide brackets securely attached to both the right and left outside slide sections, install both sections to the inside right and inside left of a 19” rack with two bolts per bracket, making sure there is adequate room for the 2RU height (3.5”) of a FM500ES system. 5. Carefully insert the FM500ES system into the 19” rack so that the inside slides on both sides of the chassis travel smoothly into the channels of the outside slide sections. Push the system into the rack until the mounting brackets on 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. 10-32 Threaded Rack-Mount Slide Holes (2) Figure B-1.
