b) Connecting drain hole T
Standard motors are supplied without a drain hole. In this case the motor is equipped with internal drainage.
This meets the requirements of the majority of applications with intermittent duty and an average drive pres-
sure of less than 50% of the motor’s maximum rated pressure.
When duty is continuous or intermittent with an operating percentage greater than 50% and the average dri-
ve pressure is greater than 50% of the rated maximum pressure, the motor must be ordered with external
drainage and drain hole T must be connected to the tank. Refer to the diagrams below:

c) Brake control
Gearmotors equipped with a brake, are available in two motor executions:
B02P or P01S.
Brake control is internal on the B02P version, and is controlled directly by the motor.
The brake control pressure must instead be supplied by an auxiliary line of the brake control circuit on the
P01S version.
Refer to the diagrams below:
d) Type of hydraulic fluid
Use hydraulic mineral fluid with viscosity ISO VG 46 (46 Cst at t = 40°C).
During operation, the fluid temperature should remain within the range +30°C to +70°C.
