5-1-2 Clamping Torque of Mounting Screws
The starter and contactor should be securely mounted to a flat surface with the fixing screws stated in the dimensions
column of the catalogue. As to the clamping torque to be applied them, refer to Table 28.

M5 25 ～ 35 －
M6 40 ～ 50 －
M8 80 ～ 100 100 ～ 150
M10 － 150 ～ 250
M12 － 350 ～ 450
5-1-3 Mounting Space
When mounting the starter and contactor, it is necessary to provide an appropriate space between them and anything
nearby. The size of this space should be determined considering the following items.
(1) Sufficient space to prevent a short circuit accident due to arc produced when opening and closing.
(2) Space necessary for normal radiation of heat generated by the starter and contactor and for holding down the
temperature rise below the allowable value.
(3) Space for securing the insulation distance specified in the standard.
Regarding the mounting space, refer to the dimension column of each type in the catalogue.
5-2 WIRING (CONNECTION)
5-2-1 Clamping Torque
For accurate wiring to terminals, refer to the clamping torque given in table in page 44 of the catalogue.
5-2-2 Connectable Wire and Usable Pressure-Type Wire Connector
The connectable wires and the widths of usable pressure-type wire connectors for the respective frames are given in
table in page 44 of the catalogue.
