 Please avoid squeezing the cable insulation layer into the AC
terminal. Improper connection may affect the normal operation of the
PCS.
 During AC cable connection, the cables inside the lower part of the
device should be bent to be surplus in length. In this way, cable
dropping or loosening, which can cause arc or other problems
impairing functionality of the device, due to self-weight of the cables
in case of land subsidence is avoided.
Step 8 Screw cap-nut tightly onto the cable.
Step 9 Seal the gaps between the AC cable and the gland inside the lower part
of the cabinet with duct seal.
Seal the gap between the cable and the gland/conduit with duct seal
or other suitable materials to prevent the entry of foreign bodies or
moisture and ensure long-term and normal operation of the PCS.
