Power Supply Notes
Power Supply Notes
Power supply specifications are shown in AC Power Input on page 115 .
Ventilation is critical for the Trinix power supplies. The power supplies
should not be run when the fan is not working. The power supply will shut
down automatically to prevent damage if the supply begins to overheat.
Note Grass Valley strongly recommends that you use redundant power supplies.
The back panel of the frame provides a separate AC connector for each
supply. Each power supply must be connected to a separate AC mains
branch circuit with an over-current protector that is rated at no more than
20A AC low line and 10 A AC high line.
Note Grass Valley strongly recommends, whenever possible, using the AC high
line to reduce line currents and heat within the power supplies.
The following fuses: F101, F105, F110- F113, F201, F205, and F210-F213 Must
be replaced with fuses that are rated “5A 125V Fast Acting” (GV PN: 59-
5053-00, LITTELFUSE PN: 39515000440). These fuses are accessible from
the rear panel. The location for the rear cover for each of the frames is
