Ac Module (Cubicle D) - Ingecon Sun 250 M220 Indoor Installation Manual

Installation manual
Handling
To manipulate elements inside cubicles B (power module 1 and 2) and c (power module 3 and 4), you must first
power down.
To disconnect the voltage it is necessary to:
1. Stop the inverter associated with the unit from the display by switching status to stop or by using the emer-
gency stop button located in the inverter 1 module (cubicle B).
2. Open isolating switches -Qdc1, -Qdc2, -Qdc3 and -Qdc4 in the Dc module (PV array). (*)
3. Isolate PV array powering cubicle A (module Dc) from outside the panel. (**)
4. cut three-phase supply (circuit breakers -Qac1,-Qac2, -Qac3 and Qac4 located in cubicle D of the Ac
module). In the absence of an Ac module, cut three-phase power from the protection outside the unit.
5. cut the single-phase auxiliary feed voltage to x220 terminals (cubicle D) from the corresponding protection
outside of the panel and from the -Qaux protection located in the power module (cubicle B).
6. Wait 10 minutes for the internal capacitances to discharge (harmonic filter), for the existing internal resistors
to cool and the fan blades to stop turning.
7. check that there is no voltage by using an appropriate multimeter. use the PPe listed in the "Important
safety conditions" section.
8. Signal cut-off points (Dc/Ac) with a sign indicating the type.
(*) When the Dc module circuit breakers (cubicle A) and the Ac module circuit breakers (cubicle D) or the external
switch, if there is an Ac module, are switched to the OFF position (no voltage) a consignment lock will be placed on
the door knobs (mechanical lockdown) and a sign reading "Do not touch. Personnel at work" will be posted.
(**) If the PV array powering cubicle A (module Dc) cannot be isolated from outside the panel. It should be taken
into account that the feed of the Dc isolating switches will be live and work must be done with the appropriate PPe
(dielectric gloves appropriate for the operating voltage, face shield, safety boots, work clothes, fire-retardant clothing
recommended, etc.).

4.5.3. Ac Module (cubicle D)

Opening system: cubicle door D (Ac) is opened and closed by a handle with a double-bit lock. Door mechanically
interlocked via four controls in the Ac breaker door.
Inspection
Inspection work may be performed in this cubicle with the unit live.
control
Performing any type of control tasks in this cubicle is not allowed.
The preventive measures for control tasks are the same are for inspection tasks.
Handling
To carry out handling on the unit, the voltage must be disconnected.
1. Stop the inverter associated with the unit from the display by switching status to stop or by using the emer-
gency stop button located in the inverter 1 module (cubicle B).
2. Open the automatic circuit breakers in the Ac panel itself (*).
3. cut the feed voltage to auxiliary Ac terminals (1,2,3,4) from the corresponding protection outside the panel
4. Isolate PV array powering cubicle A (module Dc) from outside the panel. (**)
5. cut the single-phase auxiliary feed voltage to x220 terminals (D cubicle) from the corresponding protection
outside the panel. The new mechanical set-up, the QAux switch that protects the 230 Vac auxiliary power supply
is located in cabinet 1. This control task should be noted for cubicle B (cabinet 1) in option 4x and 2x and cubicle
A (cabinet 1) in option 3x.
6. Wait 10 minutes for the internal capacitances to discharge and for internal resistors to cool.
7. check that there is no voltage by using an appropriate multimeter. use the PPe listed in the PPe section.
8. Signal cut-off points (Dc/Ac) with a sign indicating the type.
