ESR2800/3000MkII · Getting Started
Cooling
The ESR2800/3000MkII Amplifier has a comprehensive cooling system featuring chassis sealed PCB board mounting and
shock mounted, speed controlled fans. This means that the cooling system never drives air across PCB boards, connectors
or components, ensuring prolonged electronic component lifespan and minimizing maintenance cycles.
Air is drawn into the front of the amplifer by the two fans on the rear panel, this passes over the cooling fans of the heat sinks
and exhausts through the rear. If the heat sink gets too hot, its sensing circuit will open the output relay, disconnecting the load.
It is important to have an adequate air supply at the front of the amplifier, and enough space around the rear of the amplifier to
allow the cooling air to escape. If the unit is rack mounted, do not use doors or covers on the rear of the rack, the exhaust air must
flow without restriction. If you are using racks with closed backs, use fans on the rear rack panel to ensure an ample air supply.
IMPORTANT! Please note that for correct full performance of the unit AND ANY WARRANTY COVER,
it is important that regular maintenance of the front vents and filters as well as the rear panel fans be inspected
and cleaned by removing any dust and debris build-up. Any product failure due to lack of attention in this matter will
immediately void any current warranty. (Please refer to notes re ventilation procedures).
AC Requirements
Two PowerCon cables are provided to connect the ESR2800/3000MkII Amplifier to a suitable AC power supplies. Each cable
powers each separate amplifier channel for sufficient current delivery.
THE ESR2800/3000MkII REQUIRES A GROUND CONNECTION. ALWAYS USE A GROUNDED OUTLET AND PLUG.
The PowerCon is a connector without breaking capacity, i.e. the PowerCon should not be connected or disconnected under
load or while it is live. Always isolate your AC supply before disconnecting the PowerCon connector.
The ESR2800/3000MkII amplifier operates in either 115V, 230V or 250V modes. Although pre-configured at the factory, the
unit's operating voltage mode can be changed in the field. Amplifier power plug must remain readily operable.
Your amplifier will be supplied preset to the voltage used in your area. The table below provides typical current draw figures
for the ESR2800/3000MkII Amplifier.
The receptacle must be connected to a fuse or circuit breaker. Connection to any other type of receptacle poses a shock
hazard and may violate local electrical codes.
Do not allow water or any foreign object to get inside the amplifier. Do not put objects containing liquid on or near tne unit.
To reduce the risk of overheating the amplifier, avoid exposing it to direct sunlight.
Do not install the unit near heat-emitting appliances, such as a room heater or stove. This amplifier contains potentially
hazardous voltages. Do not attempt to disassemble the unit. The unit contains no user serviceable parts, repairs should be
performed only by factory trained service personnel.
