7.1 Connection of the main circuit
(1) Screw size: M5
(2) Maximum fastening torque: refer to the specification sheet.
(3) Length of the screw: Check the depth of screw holes on the outline drawing.
Adjust the length of the screws depending on the types of screws used if necessary.
7.2 Clearance and creepage distance
It is necessary to keep enough clearance distance and the creepage distance (defined as (a) in
Figure 9) from the main terminal to secure desirable insulation voltage. The clearance distance and the
creepage distance must be longer than the minimum value shown in below.
Suitable insulation distance between a bus-bar and the main terminal screw of the module shall be
designed when the module is installed to a power system.
Screws for tightening a control board on the module shall be electrically isolated. And the screws
shall be appropriately selected by taking account of insulation distance between the control terminals
of the module and the screws.
