General Safety
This chapter summarizes the safety-related information that you should both understand and observe when working
with Motorola TETRA Stations (MTSs). 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.

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: This MTS Service Manual is intended for trained technicians experienced with Motorola 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 cabinet to prevent injury 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.
