shown in "Fig. 17 Detailed Drawing of Connector Pin Numbers." Wiring must be performed
by users, following the conditions below:
• The allowable current for cables: 3 A or less for each cable (the total current value for pins
1 to 16 must be 40 A or less)
• The maximum pressure for the air line: 490 kPa (5 kgf/cm
