C.Plans, one-line and connection diagrams, record form, material and tool lists, assembly sheets, manuals

D.The installer's certificate, liability insurance policy, and photos of the roof from each side

Explanation: The EC0586.01 glossary defines the CP as a physical folder with the Plano de Planta, Plano Eléctrico, Diagrama Unifilar, Diagramas de Conexiones, Formato de Registro, Lista de Materiales y Equipo, Lista de Herramientas, Hojas de Contenido y Armado, and installation manuals of the main equipment. Most performance criteria are checked against these documents.

3When corroborating the site's feasibility under EC0586.01 Element 1, which action is part of the performance criteria?

A.Redesigning the array layout on site to use more of the roof area and add the modules the client wants

B.Measuring the building's structural capacity with load tests before any of the equipment is carried up

C.Negotiating the interconnection contract and the meter change with the utility on the client's behalf

D.Checking the site against the Plano de Planta for shading obstacles, and marking risk points and a safe route

Explanation: Element 1 asks the installer to physically check that the assigned place meets the Plano de Planta conditions without shading obstacles or risks, measure the raceway distance, check materials against the list, confirm the fastening elements suit the surfaces, and identify, label, and delimit the high-risk points and the safe route for materials.

4EC0586.01 requires the installer to corroborate the building's general grounding system before installing. Besides confirming that it exists as shown in the CP, what else must be checked?

A.That the connection point is not part of a down conductor of the lightning protection system

B.That the grounding electrode is painted or coated to protect it against corrosion in the soil

C.That the neutral is disconnected from ground at the service equipment to avoid stray currents

D.That the ground rod is at least 30 cm long and driven vertically into moist soil

Explanation: Element 1 requires physically corroborating the grounding system shown in the CP and corroborating that the grounding connection point is not part of any down conductor (conductor de bajada) of the external lightning protection system. The glossary defines the down conductor with reference to NMX-J-549.

5At the load center where the SFVI will connect, what does EC0586.01 ask the installer to corroborate?

A.That the load center has a spare slot for the PV breaker, regardless of its existing protections

B.That the load center is replaced with a new, larger one in every case before the SFVI is connected

C.That its protections match the one-line and connection diagrams, reporting their condition

D.That all branch breakers are rated above 50 A so they can accept the inverter's backfeed

Explanation: Element 1 requires physically locating the AC connection points and raceway routes, corroborating that the load center's elements match the overcurrent protection capacities in the Diagrama Unifilar and Diagrama de Conexiones, visually reviewing their condition, and notifying the supervisor of what was found.

6Before installing, EC0586.01 asks the installer to corroborate the grid voltage at the load center with a multimeter or voltmeter. Which set of measurements does the standard describe?

A.Only the voltage between one phase and the metal enclosure of the load center, at no load

B.Phase-to-phase and phase-to-neutral voltages, plus the voltage between neutral and ground

C.Only the open-circuit voltage of one module in sunlight, to compare it with the grid voltage

D.The insulation resistance of the service entrance conductors, measured with a megohmmeter

Explanation: Element 1 requires checking visually that the load center has phase, grounded (neutral), and grounding conductors, and measuring the voltage between phases, from phases to neutral, and the potential difference between the grounded and grounding conductors at the terminals indicated in the connection diagram.

7When preparing tools under EC0586.01, what must the installer verify about the measuring equipment?

A.No low-battery indication, and probes and leads with their insulation intact

B.That it was bought within the last year and still has its original packaging

C.That it is the same brand as the inverter so the readings agree with its display

D.Only that it turns on and shows a reading when the probes are touched together

Explanation: Element 1 asks the installer to record the tools in the CP's tool list, check that hand tools are free of wear, damage, and deformation, check that electromechanical tools work according to their manuals, and verify that measuring equipment does not show low battery and that its probes and conductors keep their insulation.

8While checking materials against the Lista de Materiales y Equipo, the installer finds an inverter with a dented enclosure that could affect its function. What does EC0586.01 require?

A.Install it and note the damage later

B.Return it to the supplier without telling anyone

C.Straighten the enclosure with a hammer

D.Notify the supervisor about the damaged component

Explanation: Element 1 requires verifying that mechanical and electrical components match the list and are free of blows and deformations that affect their function, notifying the supervisor if any component is damaged, and handing the verified list to the supervisor.

9EC0586.01 lists an emergent situation in Element 1: the DC voltage to be handled is 1,000 V or more. What is the expected response?

A.Continue installing, since the inverter will limit the DC voltage once it starts up

B.Short-circuit the modules temporarily to lower the voltage while the wiring is done

C.Suspend work, verify with the supervisor, and request the corresponding PPE and tools

D.Split the array into two halves on site and keep working without telling the supervisor

Explanation: Because the standard covers low-voltage systems up to 1,000 V, a DC voltage equal to or above 1,000 V is an emergent situation. The expected response is to suspend the installation, verify with the supervisor, and request the appropriate PPE and tools.

10EC0586.01's attitude of responsibility in Element 1 is shown by verifying, before installing, that certain items are available in addition to PPE. Which set does it name?

A.A first-aid kit, a Type C fire extinguisher, drinking water, and UV protection

B.A portable generator, an extension ladder, and a two-way radio for the crew

C.A water hose, a Type A fire extinguisher, and dark sunglasses for every crew member

D.Spare modules, a spare inverter, and extra connectors in case of damage

Explanation: The attitude item lists a first-aid kit, at least one fire extinguisher for Type C (electrical) fires, means of hydration, and protection against UV rays, in addition to the installer's PPE. The evaluation requirements also call for a first-aid kit, a Type C extinguisher, and a contingency plan.

CONOCER Instalador Fotovoltaico: Suggested Study Strategy

1Know the Carpeta del Proyecto documents, because most EC0586.01 criteria are checked against the Plano de Planta, Plano Eléctrico, Diagrama Unifilar, Diagramas de Conexiones, and Hojas de Contenido y Armado.

2Memorize the electrical checks: each module's Voc within ±15% of STC, Isc not zero, and string Voc within ±15% STC and below the inverter's maximum input voltage.

3Learn the emergent situations and their responses: DC voltage of 1,000 V or more, a drilled hidden pipe, heat stroke, an inverter error code, and synchronization in under 1 minute.

4Practice NOM-001-SEDE-2012 Article 690 calculations: cold-temperature Voc correction, the 600 V dwelling limit, the 156% factor from 690-8, and the 120% bus rule in 705-12(d)(2).

5Remember the anti-islanding check: open the inverter's AC disconnect and verify no voltage at the output and no current in any output conductor.
