General Safety
This chapter summarizes the safety-related information that you should both understand and observe
when working with Motorola Transceiver Stations (MTS). In addition to the information contained in this
chapter, additional safety-related information can be found in other parts of the document.
IMPORTANT: This is not an exhaustive list of all the precautions and safety measures. Before
carrying out any task with the MTS or associated equipment, implement all local and site safety
measures.
For full instructions and guidelines, see the Motorola Standards and Guidelines for Communications
Sites, R56 document.
2.1

General Safety Precautions

WARNING: During thunder storms, do not service any base station or infrastructure items.
WARNING: Any device (for example, a power supply) providing isolation between the mains
and the MTS must provide reinforced insulation to hazardous voltages. The DC power source
providing power to the MTS must comply with requirements specified for a safety extra low
voltage circuit (SELV) per EN60950.
WARNING: To reduce the risk of injury, use appropriate equipment and number of personnel
whenever moving an MTS cabinet.
WARNING: The MTS Service Manual is intended for trained technicians experienced with
Motorola Solutions Base Radio equipment or similar types of equipment.
WARNING: Use extreme caution when wearing a conductive wrist strap near sources of high
voltage. The low impedance provided by the wrist strap also increases the danger of lethal
shock should through accidental contact with high-voltage sources.
WARNING: Ensure that all power to the power supply equipment is off to prevent accidental
contact with high energy and injury to personnel.
WARNING: RF energy burn hazard. Disconnect power in the MTS cabinet to prevent injury and
equipment damage while disconnecting and connecting antennas.
WARNING: Ensure a good connection between the electrical system ground and site ground to
prevent excessive voltage potential between the two ground systems during lightning strikes.
WARNING: If cooling fans are fitted, they are exposed after removing the modules from the
rack. Touching the running fans poses an injury risk.
WARNING: Do not key the base station without a proper load. Risk of burn incidents and
damage to the MTS base station.
CAUTION: Provides a short circuit protection closest to the batteries in the battery installation.
CAUTION: To prevent damage of the MTS modules by static discharge, always wear the ESD
strap when servicing the MTS equipment.
CAUTION: Ground all antennae cables at the point that they enter the building.
