[. . . ] Do not store the receiver at temperatures outside the range ­40 °C to +70 °C (­40 °F to +158 °F). The internal battery will only charge from an external power source that delivers more than 15 volts, for example, an AC power adaptor. The receiver is supplied with a mains power supply unit that recharges the battery inside the receiver when it is connected through the adaptor to the multiport adapter or the Lemo port. When you use the receiver on large projects, from a permanent or semi-permanent base station location in a site trailer, Trimble recommends that you use this power supply at all times to keep the internal battery charged. This provides an uninterrupted power supply and will keep the site operational for up to 6 hours after a power failure. Keep all batteries on continuous charge when not in use. You can keep batteries on charge indefinitely without damage to the receiver or to the batteries. Removing the rechargeable Lithium-ion battery The internal Lithium-ion battery should be removed only at an authorized Trimble Service Center. If the battery is removed at an unauthorized service center, the remaining warranty on the product will be void.

It also describes how to connect the receiver to external devices. NetR3 GNSS Reference Sensor User Guide 21 4 Setting up the Receiver Setup guidelines When you set up the receiver, follow these guidelines. Environmental conditions The receiver has a waterproof housing. However, you should take reasonable care to keep the unit dry. To improve the performance and long-term reliability of the receiver, avoid exposing the receiver to extreme environmental conditions, such as: · · · · Water Heat greater than 65 °C (149 °F) Cold less than -40 °C (-40 °F) Corrosive fluids and gases Sources of electrical interference Avoid locating the GNSS antenna near the following sources of electrical and magnetic noise: · · · · · · · Gasoline engines (spark plugs) Televisions and computer monitors Alternators and generators Electric motors Equipment with DC-to-AC converters Fluorescent lights Switching power supplies Uninterruptible power supply Trimble recommends that you use an uninterruptible power supply (UPS) to power the receiver. The internal battery can also operate as a UPS for up to 6 hours. A UPS protects the equipment from power surges and spikes, and keeps the receiver running during short power outages. For more information, contact your local Trimble dealer. Lightning protection Trimble recommends that you implement lightning and electrical surge protection equipment at the NetR3 installation site. A complete protection system should address the GNSS antenna feed, the AC power supply, the Ethernet connection, and any connected serial connections. 22 NetR3 GNSS Reference Sensor User Guide Setting up the Receiver 4 As a part of the surge protection plan, the installation site should have a properly-designed grounding system that connects to a single ground point outside the reference station enclosure. Placing the antenna Carefull plan where you will position the reference station antenna. To ensure accurate reference station operation, make sure that the site is as free as possible from sources of GNSS signal interference. Make sure that the antenna: · · · · has a clear view of the sky to the horizon within a 100 m radius is at least 1. 5 m higher than any items that could reflect GNSS signals is at least 300 m from any high-power transmitting antennas is stable in changing temperatures and weather conditions Connecting the receiver to external devices You can connect the receiver to the following devices: · · · GNSS antenna Ethernet communications Serial devices GNSS antenna The receiver provides a TNC-type female connector for connecting to a GNSS antenna. The receiver is intended for use with a Zephyr GeodeticTM Model 2 antenna or a Trimble GNSS Choke Ring antenna Antenna cabling Many permanent GPS installations have unique cabling requirements. Depending on the available infrastructure, you may need to mount the antenna a substantial distance from the receiver. The receiver can withstand a loss of 12 dB between the antenna and the receiver. The degree of loss in a coaxial cable depends on the frequency of the signal passing through it. The following table lists some common types of cable and the maximum length you can use before you need an inline amplifier . Cable type LMR-400 LMR-500 LMR-600 Maximum length for use without an inline amplifier 70 m (230 ft) 85 m (280 ft) 106 m (350 ft) NetR3 GNSS Reference Sensor User Guide 23 4 Setting up the Receiver Cable type Heliax LDF4/50 Heliax.
