NX5 PRE-INSTALLATION MANUAL PRE-INSTALLATION TASKSVERSION 0.1 2015-08-01 PAGE 1.2.1SECTION 1.2: PRE-INSTALLATION TASKSThis section provides a list of tasks that you must perform prior to delivery and installation of the NX5transmitter.To prepare for installation of an NX5 transmitter, perform the following tasks:1. Ensure that the correct transmitter configuration is ordered. Check the ac power requirements,preset frequency and other options. Complete and return the technical questionnaire provided byyour Nautel Sales Agent.2. Consider the method of shipping when placing an order. The standard “upright” configurationallows the power transformer to remain in the transmitter cabinet for shipping. If space constraintsrequire another method of shipping, inform your Nautel Sales representative.3. Select a location for the transmitter in the transmitter room. Determine whether additionalheating, ventilating or cooling capacity is needed at the site. Identify any special requirementsregarding air flow around the cabinet (for example, ducting hot air away from the cabinet, orbringing in external cooling air). See “Selecting a Location for the Transmitter” on page 1.3.1.4. If you are planning to anchor your transmitter against seismic activity, prepare the transmitterroom floor to accept four anchoring bolts. Four 5/8-inch (16 mm) holes are provided in thetransmitter floor to allow this (see Figure 1.3.5 on page 1.3.8 for hole location). Square washers areprovided in the ancillary kit to aid in anchoring the transmitter (see NX5 Installation Manual).5. If this is an upgrade or replacement transmitter (that is, if the site is already set up for atransmitter), go to Step 10. (If you are upgrading a site, verify the feedline, the lightning protectionsystems, and the ac power service. Refer to Nautel’sRecommendations for Transmitter SitePreparation Manual.)6. Install ac power service into the planned location of the transmitter, and select a location for an acpower switch near the transmitter location. For detailed information, see “Electrical Power” onpage 1.5.2.Be aware of lightning protection issues when installing ac power. Lightning protection is essentialto protect both personnel and equipment at your site. Refer to Nautel’sRecommendations forTransmitter Site Preparation Manual.7. Install a safety power interlock switch in series with the ac power service installed in Step 6. Nautelmay provide an optional keyed interlock system that will meet this requirement.WARNING!
