5. Setting the NT4G19EA Power Supply
for 115 or 220 Vac Operation
The system uses a 115 or 220 Vac commercial outlet as its power source, depending
on the number of cabinets. The power supplies shipped with NSR26 and later
systems adjust automatically for operation with either 115 or 220 Vac, according to
the power supply they receive. (Power supplies in this category are the Loft Power
Supply and the Universal Power Supply SRU, NT4G19FA.)
The NT4G19EA Power Supply SRU was shipped with systems prior to NSR26. The
NT4G19EA Power Supply SRU has an input voltage setting (for 115 or 220 Vac)
that must be verified before the SRU is installed in the cabinet. The power input
option is normally set for 115 Vac operation at the factory. This setting serves
systems of up to four cabinets. In systems with five or more cabinets, the SRUs
must be set for 220 Vac. In such installations, you should verify that the setting is
correct before installing the SRUs.
