Cooling
AC Requirements
The ESR3000 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.
NOTE: The filters at the top and bottom of the front panel must be kept clean and free of dust and dirt to
allow full operation - CHECK PERIODICALLY.
Two PowerCon cables are provided to connect the ESR3000 Amplifier to a suitable AC power supplies. Each
cable powers each separate amplifier channel for sufficient current delivery.
CAUTION: The ESR3000 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 ESR3000 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 ESR3000 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.
