Important Safety Information
Do not perform any procedure in this Special Instruction until you have read this Special Instruction and you understand this information. Use only proper tools and observe all precautions that pertain to the use of those tools. Failure to follow these procedures can result in personal injury. The following procedures should also be observed.
Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs.
A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools to perform these functions properly. Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons. Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. Therefore, the warnings in this publication and the warnings that are on the product are not all inclusive.
Ensure that any tool, procedure, work method, or operating technique you use that is not recommended by Caterpillar is safe. Ensure that the product will not be damaged or the product will not be made unsafe by the operation, lubrication, maintenance, or repair procedures used.
Do not operate or work on this machine unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Caterpillar dealer for replacement manuals. Proper care is your responsibility. |
Only persons with training in electrical installations must carry connections to the generator. The generator must be wired correctly. A fire or electrocution could result from wiring that is incorrect. The generator is capable of generating high voltages. Ensure that the generator is not on while the connections are being made. Follow these steps in order to prevent accidental starting:
|
Accidental engine starting can cause injury or death to personnel working on the equipment. To avoid accidental engine starting, disconnect the battery cable from the negative (−) battery terminal. Completely tape all metal surfaces of the disconnected battery cable end in order to prevent contact with other metal surfaces which could activate the engine electrical system. Turn the battery disconnect switch to the OFF position and lockout the battery disconnect switch with a safety lock. Place a Special Instruction, SEHS7332, "Do Not Operate" tag at the start switch and battery disconnect location to inform personnel that the machine is being worked on. |
Improper operation of an access platform could result in injury or death. Operators must carry out their duties properly and follow all instructions and guidelines given for the machine and access platform. |
Do not connect generator to a utility electrical distribution system unless it is isolated from the system. Electrical feedback into the distribution system can occur and could cause personal injury or death. Open and secure main distribution system switch, or if the connection is permanent, install a double throw transfer switch to prevent electrical feedback. Some generators are specifically approved by a utility to run in parallel with the distribution system and isolation may not be required. Always check with your utility as to the applicable circumstances. |

Mounting Requirements
The mounting requirements are listed below:
- PLG6x1 must be mounted in a sealed location with no exposure to high-pressure spray or underwater immersion. Exposure to high-pressure spray or underwater immersion will lead to device failure.
- When using the PLG641 with optional dual-mode antenna, the external antenna must be mounted in a horizontal orientation.
- The standard GPS antenna and optional dual-mode antenna must have a clear line of sight to the sky. Usually, the canopy/ container roof will provide an optimal view of the sky with minimal blockages.
- Do not mount the PLG6x1 or antennas in an area with exposure to extreme conditions of heat.
- Locate the antennas so that the connectors are not exposed to high-pressure spray or underwater immersion. Exposure to high-pressure spray or underwater immersion may compromise the connector seals and lead to connection failure.
- Keep a distance of no less than
500 mm (19.6 inch) between the PLG641 radio and other antennas that transmit a radio signal. The lists of radio antennas to maintain a distance from include the citizen band radio, data radio, and commercial communication radios. - Keep in mind the routing of the coax antenna cable. Route the cable such that the cable is not subject to abrasion or pinching. Do not route the cable near any source of extreme heat (exhaust). Do not mount the cable so that the limitations of temperature
−40° C (−40.0° F) and85° C (185.00° F) are exceeded. - Route the coax antenna cable with a minimum bend radius of
49.5 mm (1.94 inch) . Bend radius depends on the type of cable used. Do not bend the radius any less than ten times the diameter of the cable.
PLG Mounting:
Place the PLG6x1 in the desired mounting location. Take note of accessibility to the backside of the mounting location. This action determines what mounting hardware to use.
