1.Unscrew connecting screws on the base and
cover counterclockwise, and open the cover;
2.Use some tool to pierce the rubber seal rings
on both sides for later wiring;
3.Connect the main circuit, control circuit and
grounding screws, adjust the setting current
value of the thermal relay; and install the
product according to the requirements;
4.Put the cover on and tighten the connecting

Figure 10 Starter installation diagram
Note 1: The connecting wires of the incoming and outgoing lines of the main circuit must
be single-core PVC insulated copper cables with prefabricated terminal, whose cross-
sectional area is specified in Table 5; the cross-sectional area of connecting wires of the
auxiliary circuit should be 1mm². Tighten all the screws during wiring to prevent the starter
from slipping and fall due to vibration. Remove the residual of foreign objects to prevent
the moving parts of the contactor from getting stuck and the occurrence of short-circuit
accidents.
Note 2: Choose screws no smaller than M5 according to the size of the mounting hole.
Add seal ring to the screw to ensure enclosure protection class.
