Precautions
Following All Safety Precautions Before any operation, read the instructions and precautions in this document carefully to minimize the possibility of accidents. The Danger, Caution, and Note items in the documents do not cover all the safety precautions that must be followed. They merely provide the most basic generic safety precautions that are applicable for this equipment. When operating VNL® products and equipment, you must comply with all safety precautions, while also follow additional special safety instructions related to corresponding equipment provided by VNL®. The safety precautions in the document are related to only VNL® products. VNL® is not liable for any consequence results from the violation of universal regulations for safety operations and safety codes on design, production, and equipment use
Complying with Local Safety Regulations When operating the device, comply with the local safety regulations. The safety precautions provided in the documents are supplementary. You must comply with the local safety regulations.
Qualified Personnel Only The personnel in charge of installation and maintenance must be trained and master the correct operating methods and safety precautions before beginning work.

DANGER Indicates a hazard with a high level of risk, which if not avoided, will result in death or serious injury.
WARNING Indicates a hazard with a medium or low level of risk, which if not avoided, could result in minor or moderate injury. CAUTION Indicates a potentially hazardous situation, which if not avoided, could result in equipment
damage, data loss, performance degradation, or unexpected results. TIP Indicates a tip that may help you solve a problem or save times. NOTE Provides additional information to emphasize or supplement important points of the main text.
Grounding of the site equoperation or not. Never perform any site work during a thunderstorm. There are no user serviceable parts inside the VNL® Any attempt to access any parts inside may result in serious injury or even death. Defective or malfunctioning units should be replaced and returned in unopened conThe VBTS site is equipped with batteries of very high peak current capability and high energy. The VNL® battery stencil shows the proper polarity and is intended to help with safe assembly. Extreme caution must be taken until the battery terminals are secured. Severe burns or blindness can result during short circuit of battery cables.
Device Safety Check the electricreliably grounded. When working on batteries, take measures to prevent short circuits in the batteries. When the equipment is unpacked, it must be powered on in 24 hours. The maximum duration of the power-off state of the equipment is 24 hours during maintenance.

Features with Key Components
specially designed for demanding outdoor applications in rural areas. It is fed by 24V DC and comes with integrated microwave link and antenna.
Internet wireless access point available Optional wireless access point for internet access can be fitted and fed via 24V PoE from the VBTS.
Simple setup The entire installation involves erecting the supporting structure for the solar panels and battery compartment, erecting the pole with BTS and integrated microwave link can be done in two hours.
VNL® OMC supervision and alarm handling support included All relevant real time site parameters, including battery state of charge (SOC) have remote supervision support, allowing informed decisions to be made with respect to service or repairs.
Solar power system with hybrid AC power support included The main consideration is keeping solar panels clean and ensuring proper seasonal alignment on at least a monthly basis. In very clean environments with limited inaccessibility, like mountainous areas at considerable altitude, a check every three months would be adequate, unless the OMC reports any alarm that calls for manual intervention.
Solar power optimized zero maintenance batteries The battery technology chosen is tubular gel VRLA in discrete 2V cell configurations of 12 cells per system. For safety reasons, the battery compartment is kept closed with a remotely monitored top cover sensor. There is no topping-up or other service required for the duration of the VNL® warranty time period. In the event that some form of physical or chemical damage has occurred due to abnormal operating conditions, only the original cell type may be replaced. Due to lead content, controlled recycling is mandatory to prevent harm to humans, domesticated or wild animals or plants.
Always keep in mind that lead in any shape and form must be handled responsibly by personnel with adequate training, for additional information, turn to VNL® after sales support.

Post-Installation Site Audit
© VNL® 2009‐2010, All rights reserved
The following should be performed for all BTS sites:
• Check the termination of the Ethernet cable to the CCU-100 and the combiner. Check the quality of crimping by visual inspection. Ensure that all interconnections batteries, SPV, and CCU-100 are still firm and without corrosion. Confirm that all (green) grounding cabling is intact and bolts tightened firmly.
• Ensure that that there is no damage or gaps in the sheet metal battery enclosure and that no equipment is left inside. Check that the remote alarm connector of the compartment lid is working.
• Check for solar panel damage to the cover glass and also for any small air bubbles trapped between the silicon cells and laminate near the frames, if so, the panel should be replaced.
• Confirm the north-south solar stand axis of alignment by means of a compass and
