● Prevention against wetting
The motor, as a single unit, satisfies the IEC standard. Since the standard, however, is intended to
check performance over a short period of time, the following measures against wetting are required for
actual usage. Handle the system carefully, or the connector sheathes may be hit or damaged,
deteriorating waterproof function.
The cannon plug type P1, P2 and P6 as well as the P8 series motor become equivalent to IP67 by using
a waterproof connector or conduit on the other side of the cannon connector.
The P3 series motors and the P5 series motors with the flange size of 30 mm and 40 mm sqs. have
waterproofing equivalent to IP40 and the P5 series motors with the flange size of 50 mm, 70 mm and 80
mm sqs. to IP55.
• Set the connector (lead outlet) with its end downward in the angle range shown in the following
figure.
• Install the cover on the side to which water (oil) will splash.
• Install the cover with a gradient so that water (oil) may not stay.
• Avoid dipping the cable in water (oil).
• Slacken the cable outside the cover so that water (oil) may not invade the motor side.
