Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). Paragraph (d) of this section also applies to protective grounding of other equipment as required elsewhere in this Subpart. This helps to reduce the potential difference that exists between conductive parts and the earth. Equipment Protection: Grounding protects substation. Power from factory ground must be installed by a qualified electrician. Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. The concept is a simple one: provide a path for ground current via a resistance that limits the current magnitude, and.

Since it uses passive devices, it doesn't require an extra power supply, leading to lower overall power consumption in the network. PON network does not require electrical power to send signal to customers The PON Network will be introduced in this article, which mainly involves the basic components and related technology including OLT, ONT OR ONU, and ODN. Data is received at its input in electrical form, which converts it into an optical signal and transfers data through optical fiber cables to the splitters or. PON (Passive Optical Network) refers to a fiber optic network that uses point-to-multipoint topology and optical splitters to transmit data from a single point of transmission to multiple user endpoints. It aggregates multiple ONUs/ONTs through optical splitters and handles data distribution, management, and synchronization.
