XR12 OPERATIONS AND MAINTENANCE MANUALPAGE XVI VERSION 3.1 2013-03-14Safety InterlocksThe transmitter contains an electrical interlock, which is an external circuit that turns off the RF outputif any of its switches are opened.Ac Disconnect SwitchSafe operation of the transmitter requires an ac disconnect switch. Lock the ac disconnect switch in thedisconnected (open) position during the installation process.Equipment SafetyElectrostatic ProtectionThe transmitter’s systems are very rugged and resistant to damage. However, it is possible for damageto occur because of high voltage electrostatic discharges during servicing. Train all service personnel toground themselves to bleed off any static charge before opening the transmitter or touching anyexposed components. Provide a grounding wand or known ground (e.g., a grounded metal table) thatpersonnel can use to discharge themselves.Surge ProtectionSurge protection is recommended for your entire site. However, even if you do not use a surge protectoron the service entrance to the site, you should install a surge protector in the transmitter’s ac powerfeed to prevent over-voltage from entering the transmitter.Lightning ProtectionThe transmitter is designed to resist lightning strike damage. However, intense or repeated strikes coulddamage the transmitter. We recommend that you install lightning suppression on the antenna, towerand feedline to reduce the effect of lightning strikes on the transmitter itself (and to protect the rest ofyour site equipment and your personnel). For detailed information about lightning protection, see theNautel Site Preparation Manual, available from your Nautel sales agent, or online from the Nautelwebsite.
