If condensation is likely to occur when the drive is not in use, install an anti-
condensation heater. This heater must be switched off when the drive is in use;
automatic switching is recommended.
Install the drive so that the heatsink fins are vertical for best flow of cooling air.
Observe the requirements for ambient temperature if the drive is to be mounted directly
above any heat generating equipment (such as another drive). When the ambient
temperature exceeds 50°C (120°F), the output power of the drive must be derated. The
drive has over-temperature protection which trips the drive when the heatsink reaches
100°C (212°F).
Figure 2-2 Derating the maximum output current with temperature
If the drive is to be installed directly beneath other equipment (such as another Variable
Speed drive), ensure the drive does not cause the ambient temperature requirements of
the equipment to be exceeded.
Leave adequate clearance around the drive to allow unimpeded airflow to the heatsink.
For model DCD60x14/28, apply forced cooling using a fan and cabinet of adequate
size.
The total power dissipated as heat from a drive, choke, transformer and heatsink is 10%
to 15% of the motor power.
