Introduction
The control is designed with a NEMA-1 / IP-40 enclosure for indoor use. It is recommended that the
control be mounted vertically on a flat surface with adequate ventilation. Leave enough room below
the control to allow for AC line and motor connections and any other connections that are required.
A mounting template is included to facilitate mounting of the control.
Control installation must ensure unrestricted air flow through the heatsink cooling fins.
Note: If drive is mounted in other than a vertical position, decrease maximum allowable ambient
temperature by 10°C.
Front Cover
- The control is designed with a removable cover. To remove the cover, the two screws
must be removed.
After mounting the control and all connections are completed, install the cover and secure it with the
two screws. Tighten the screws to 5 lbs-in (6 kg-cm). Do not overtighten.
