Branch Circuit Schematic
The 884PS-48 power supply differs from other Leitch power supplies in that it
depends on the studio’s installed circuit breaker/fuse to disconnect power to the
frame.

WARNING To reduce the risk of electric shock or energy hazards:
• Connect the 884PS to a reliably grounded SELV source or a centralized DC source.
• Make sure the branch circuit overcurrent protection is rated a maximum 15A circuit
breaker in series with a maximum 5A listed fuse. (See “Suggested Protection Devices”
section on page 45.)
• Use 14 AWG solid copper conductors only.
• Incorporate a readily accessible, suitably approved, and suitably rated disconnect device
into the field wiring. (See“Suggested breaker switch type” section on page 45.)
• Install the 884PS in a restricted access area in accordance with the NEC or the authority
having jurisdiction.
WARNING To reduce the risk of electric shock:
• Perform installation and exchange only you are a trained technician who is familiar with
these instructions and aware of the shock hazards of working with live equipment.
• Install the 884PS-48 power supply in accordance with the schematic diagram shown in
Figure 13-1. Power can only be disconnected completely from the 880 series frame
through a studio installed breaker or fuse.
