(4) Drip-proof environment
The protection form for a single motor unit satisfies IP65 of the
IEC standards (equivalent to JP65, dust-proof and jet-proof type,
of JIS C4004-1980, code for revolving electric machines) These
standards, however, refer only to short-term performance. In
actual operation, note also the following:
(a) Protect the motor surface from the cutting fluid or lubricant.
Use a cover when there is a possibility of wetting the motor
surface. Only the telescopic cover of the sliding part can
not completely prevent leakage of the cutting fluid. Pay
attention to the drop along the structure body, too.
(b) Prevent the cutting fluid from being led to the motor
through the cable. When the motor connector is used in the
sideways position, put a drip loop in the cable.
