4.5.1. Dc module (cubicle A)

Opening system: cubicle door A is opened and closed by a handle with a double-bit lock. Mechanically interlocked
door via controls in the isolating switch door.
Inspection
The protective elements (methacrylates) of the terminals and connection plates should be properly positioned at all
times (avoid direct access to live parts).
control
The only control task which can be carried out on this Dc panel is the communication with the team via the commu-
nication terminal strip (cOM).
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.
The following points must be taken into account to disconnect the unit from the power supply:
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 cubicle B. using the emergency stop button shuts down all power modules at the
same time.
2. Open all isolating switches in the Dc panel itself (PV array). (*)
3. Isolate PV array powering cubicle A (module Dc) from outside the panel. (**)
4. Wait 10 minutes for the internal capacitances to discharge and for internal resistors to cool.
5. check that there is no voltage by using an appropriate multimeter. use the PPe listed in the PPe section.
6. Signal cut-off points (Dc/Ac) with a sign indicating the type.
(*) When the Dc module isolating switches (cubicle A) and the Ac module circuit breakers (cubicle D) 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 (i.e.,
dielectric gloves appropriate for the operating voltage, face shield, safety boots, work clothes, fire-retardant clothing
recommended).
Any work carried out which implies a modification of the original electrical settings must be proposed to and accepted
by Ingeteam.

4.5.2. Power modules 1-2 and 3-4 (cubicles B and c)

Opening system: Access doors to the inverter module 2 (cubicle c) and power module 4 (cubicle c) are opened and
closed by a handle with a double-bit lock. For opening and closing the doors to power module 1 (cubicle A) and power
module 3 (cubicle c) you will need to open the doors to inverter module 2 and power module 4.
Inspection
Inspection tasks with the unit live are not allowed in these cubicles.
control
The only control tasks that can be performed in cubicle B (power module 1 and 2) and cubicle c (power module 3
and 4), are:
• Settings from existing display in inverter 1 door module (cubicle B). This task must be carried out with the
doors closed and the unit powered up.
The preventive measures for control tasks are the same are for inspection tasks.
