POWER DISTRIBUTION
Power distribution is a confusing and difficult area to estimate. Choosing the correct
cable conductor is of major importance to minimize systems costs while maintaining
power requirements for the equipment used. Minimum power requirements of PTZ site
receivers, cameras, and other remote equipment must be observed with respect to total
load on the power feed and voltage fluctuations caused by varying load demands of the
equipment (PTZ operation etc). This should NOT be calculated on an average
consumption basis. Maximum (worst case) conditions should always be assumed.
Rev. C
WARNING: Always disconnect the mains power supply
before accessing the equipment to be serviced.
WARNING: All mains powered equipment should be
connected via a locally mounted switched GPO outlet.
Direct mains connection is illegal.
WARNING: When servicing equipment, the use of
SERVICE TAGS should be employed at switchboards,
circuit breakers, fuses and/or mains outlets to warn other
personnel that the distributed power feed has been
isolated.
WARNING: All precautions should be observed to
prevent ELECTRICAL SHOCK.
