Dc Mains Grounding Connections; Disconnect Device Permanently Connected; Multiple Power Sources; Connection To Primary Power - Motorola ASTRO 25 GTR 8000 Manual

• When installing the equipment, all requirements of relevant standards and local electrical codes
must be fulfilled.
• The maximum operating ambient temperature of this equipment is 60 °C. The maximum operating
altitude is 3000 meters above sea level.
• The 28.6 VDC output from the power supply to the PA is at an energy hazard level (exceeds 240
VA). When installing into the end system, care must be taken so as not to touch the output wires.
• When the base radio is used in a DC reverting system, the DC power supply must be located in the
same building as the base radio, and it must meet the requirements of a SELV circuit.

DC Mains Grounding Connections

CAUTION: This equipment is designed to permit the connection of the grounding conductor of
the DC supply circuit to the grounding conductor at the equipment. If this connection is made,
you must meet all following conditions:
• Connect this equipment directly to the DC supply system grounding conductor or to a bonding
jumper from a grounding terminal bar or bus in which the DC supply system grounding electrode
conductor is connected.
• Locate this equipment in the same immediate area (such as adjacent cabinets) as any other
equipment that has a connection between the grounded conductor of the same DC supply circuit
and the grounding conductor (and also the point of grounding of the DC system). Do not ground the
DC system elsewhere.
• Locate the DC supply source within the same premises as the equipment.
• Do not install switching or disconnecting devices in the grounded circuit conductor between the DC
source and the point of connection of the grounding conductor.
3.2.2.1

Disconnect Device Permanently Connected

Incorporate a readily accessible disconnect device (circuit breaker or switch) in the building installation
wiring.
3.2.2.2

Multiple Power Sources

This product has multiple power sources. If service requires the removal of a power source, disconnect
all inputs (AC and DC power) to remove power completely from the equipment before servicing.
3.2.2.3

Connection to Primary Power

For supply connections, use wires rated for at least 75°C (167°F).
3.2.2.4

Replaceable Batteries

WARNING: Risk of explosion if you replace a battery with an incorrect type. Dispose of used
batteries according to the instructions.
