POWER INSTALL provides instruction on the proper methods required to connect the power feeds which run from the telecommunications equipment into live secondary power distribution bays (BDFB). TPI Trainers has developed a mobile BDFB that will be utilized to simulate a live power environment. In class exercises provide individuals with the skills required to develop a thorough Method of Procedure (MOP).

The instruction describes the proper safety and installation procedures necessary to perform equipment additions in telecommunications facilities through the development of a comprehensive DC distribution MOP. These exercises also provide the student with the skills required to create, review or approve a comprehensive DC distribution installation MOP for installing new power cables, as well as transitioning the equipment loads from one BDFB to another without compromising service continuity.

Power connections made into live power distribution bays is considered to be a “critical work activity” in accordance with industry requirements. While Skill Level 3 and 4 installers can create a MOP, only Skill Level 4 installers qualified in performing power connectivity are permitted to perform these “critical work activities”.
It is not only paramount to recognize the importance of maintaining service continuity of the telecommunications equipment in a telecommunications facility, but also to realize that any errors during the installation process can impact other equipments served by the power system.

Who should attend: POWER INSTALL is recommended for all personnel working in a telecommunications environment. Installers will understand how to develop a quality MOP and technicians, managers and engineers will recognize what is expected when approving or observing the MOP for the addition of DC power cables.

Throughout the course knowledge assessments are used to reinforce the topics discussed. At the completion of the course you will be tested to document your knowledge. Successful completion of this test will earn TPI Trainers Certification.
Note: When POWER INSTALL is delivered to at your location our instructors can enhance your learning experience by specifically targeting the lessons learned to your specific power systems.

POWER INSTALL depicts the current industry standards and can be customized to meet the needs of your specific work group. To discuss the need to customize this course you can contact Vicki Johnson by calling 1-630-607-9302.
