E-Compact Medium Power Section 2 - Minimum Installation Requirements WARNING MANDATORY CONDITIONS FOR TRANSMITTER INSTALATION, FOR VALIDATING THE WARRANTY TERMS 1. Proper grounding; 2. Proper lightning-rod; 3. Shelter with ventilation, footprint, and temperature in compliance with the transmitter’s standards. 4. Voltage regulator in compliance with transmitter’s consumption. Noncompliance with any of above-mentioned terms will automatically result in the hereinafter suspension of the warranty terms.
E-Compact Medium Power 1. Introduction. This section provides information on the minimum installation requirements for E-Compact Series transmitters with recommendations on shelter, tower, antennas, cables, grounding, mains, transient preventions, etc. 2. Minimum Requirements. 2.1. AC Mains - Wire Gauge. Consumption with the equipment running at its maximum power. Current (A) on each wire: About AC MAINS TYPE, see Section 8 – Attachments, USA AC Mains Types for ECompact Series.
E-Compact Medium Power It is important to establish that all the devices involved in the transmission system are that the same potential, so that there is no DDP, favoring the equilibrium of the flow of the atmospheric load. It is important to state that if there is a need for chemical alteration of the soil, in order to provide the lowest impedance, it establishes a temporary condition for not being part of the natural chemistry of the place, thus being naturally absorbed.
E-Compact Medium Power No break Example with Isolating Transformer Benefits: - These types of UPS bring great protection and insulation to the transmitter due to its mode of operation and design. - The double conversion occurs because the AC network convert to DC and the DC voltage convert back to AC, which eliminates any disturbance in the AC mains when converted to DC, thus protecting the transmitter.

E-Compact Medium Power 2.5. Atmospheric Discharge Protection System. 2.5.1 Lightning rods. The Atmospheric Discharge Protection System consists of the lightning rods and their elements. The tower and shelter where the equipment will be installed must be protected against atmospheric discharges by means of lightning arresters. It is important to determine that all ferrous parts and accessories that make up the Atmospheric Discharge Protection System should be galvanized.
E-Compact Medium Power 2.6.2 Humidity. Relative air humidity inside the shelter is also considered a critical factor for improved performance and longer equipment life. Hitachi Kokusai Linear equipment should operate in dry environments, which can also be achieved by the use of air conditioners.

This section provides general information for planning the installation of the E-Compact Medium Power Line Transmitters, such as recommendations regarding Shelter, Tower, Antennas, Cables, Grounding, Power Line, Prevention against Transients, etc. 2. Inspection. The package and the equipment must be inspected upon delivery in order to detect eventual visible damages.
E-Compact Medium Power a) It feature of special insulator supports for descent of cordage of lightning rod, with a space of 1,5m maximum between them. b) There must be a lightning signaling system in every 20m along the tower. c) It must be painted with orange and white stripes in every 2m with a special paint that complies with local regulations. d) It must endure winds of up to 150 Km/h.
E-Compact Medium Power Stacking antennas When using this system, the distance between them depends on the kinds of antenna used and the kind of stacking used. This must be studied thoroughly in order to obtain the best solution for each case. Cables and Connectors All cables must be carefully installed in order not to be twisted during the installation process. When using 7/8" or 1/2" cables, please pay attention to their bending that must not be made in spaces smaller than 80cm.
E-Compact Medium Power To determine the behavior of the soil capacity to drain the currents, its resistivity has to be measured. For an adequate protection this value should not exceed 5 , being zero the ideal value Generally, the grounding method used for TV retransmitters is a system with a single vertical electrode made with copper measuring 2.5 meters or more.
E-Compact Medium Power 4. Equipment Assembly Only trained and trained personnel should conduct physical assembly on site. Observe the requirements described in this manual in Sections 1 (Care, Warranty and Service) and Section 2 (Minimum Installation Requirements).
