1-10 Revision May 2009, 00DE, V0.50
5. The heat sink temperature may rise to 90°C when running. The material on which the brushless
DC motor drive is mounted must be noncombustible and be able to withstand this high
temperature.
6. When brushless DC motor drive is installed in a confined space (e.g. cabinet), the surrounding
temperature must be within 10 ~ 40°C with good ventilation. DO NOT install the brushless DC
motor drive in a space with bad ventilation.
7. When installing multiple brushless DC motor drives in the same cabinet, they should be
adjacent in a row with enough space in-between. When installing one brushless DC motor drive
below another one, use a metal separation between the brushless DC motor drives to prevent
mutual heating.

1.2.2 DC-bus Sharing: Connecting the DC-bus of the Brushless DC motor
drive in Parallel
1. The brushless DC motor drives can absorb mutual voltage that generated to DC bus when
deceleration.
2. Enhance brake function and stabilize the voltage of the DC bus.
3. Only the same capacity and same power system can be connected in parallel.
4. The 5 drives should be in same power system, e.g. if the input voltage is 220V, the 5 brushless
DC motor drives connected in parallel must also be 220V.
