Note For more information about Power Supply connections with Asymmetric
frames, see Trinix Asymmetrical Power Supply Configurations
on
page 227 . Grass Valley strongly recommends, whenever possible, using
the AC high line to reduce line currents and heat within the power sup-
plies.
The following items should be considered during the installation pro-
cess.
Fuse Differences
Make sure that you use the correct fuse when you change from 120Vac
to 220Vac. There is a fuse difference on the rear panel of the 128 x 128,
the 256 x 256, and the 512 x 512 frames.
Note See the markings on the router’s rear panel frame for the correct Fuse
value requirements.
For additional power supply information, see Power Supply Notes on
page 151 .

rical Power Supply Configurations
