4.10.2.4 Installation and wiring of distribution equipment (read it according to your demand)
Before installing the distribution equipment, open the box for inspection first, based on the
device list, construction drawing and device technical material, check the main uint, attachment
and spare parts of the device, product certificate, technical material and specification, to see if
they are complete. Tighten the screws used for installation and check the installation strength.
Installation of junction box: install it to the place near the assembly string to decrease cable
pavement length and wire breakage. Protection measures shall be taken in the places where
cable is entering into the junction box to avoid scratching the cable. After wiring for the
conjunction box, please check the wiring strength and tightness of the box. Close the cover and
tighten with keys after inspection.
Installation of grid-connected cabinet: carry out installation according to the arrangement
of construction drawing. The cabinet shall be earthed, connect each cabinet with base
separately. Check the connecting wire of controller inside the cabinet to see if it is consistent
with circuit diagram and wiring diagram. Its rated voltage must be consistent with controlling
and operating power voltage. At last, adjust the overcurrent circuit breaker of the cabinet, all
relays and mechanical chain, etc.
