7.2 Power Supply Connections
7.2.1 AC Power
The TB8100 PMU is designed to accept a mains input of 88 to 264VAC at
45 to 65Hz. We recommend that a standard 3-wire grounded outlet is used
to supply the AC power. The socket-outlet must be installed near the
equipment and must be easily accessible. This outlet should be connected
to an AC power supply capable of providing a maximum of 600W. The
requirements of two typical AC supplies are given in the following table.
Your TB8100 BSS should come supplied
with a power supply cord to connect the
male IEC connector on the PMU to the
local AC supply. The pins of the IEC
connector on the PMU are identified at
right.
7.2.2 DC Power
DC Power with PMU The TB8100 PMU is designed to accept a nominal 12VDC, 24VDC or
48VDC input (depending on the model) with negative or positive ground.
There is a minimum DC startup threshold to prevent damaging a battery
which has little capacity left.
You must connect the DC supply from the battery to the PMU via a fuse or
DC-rated circuit breaker with the appropriate rating, as shown in the table
