Installation manual
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.
Switch on existing 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.
(*) When circuit breakers/circuit breakers/fuses (AC/DC) are switched to the OFF position (no voltage), a consignment
lock will be placed on the door-mounted control (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 circuit breakers 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.).
