3-6 Installing the Drive 590 Series DC Digital Drive
Ventilation and Cooling Requirements
Refer to Appendix E: “Technical Specifications” - Cooling Fans.
The Drive gives off heat in normal operation and must therefore be mounted to allow the free flow of air through the air entries and exits. Maintain the
minimum air clearances given on the drawings to ensure that heat generated by other adjacent equipment is not transmitted to the Drive. Be aware that
other equipment may have its own clearance requirements. When mounting two or more 590’s together, these clearances are cumulative.
Ensure that the mounting surface is normally cool.
AC Line Choke
We recommend that you always use the specified ac line choke with the Drive
to provide a known supply impedance for effective operation of the thyristor transient suppression circuits. At least 1% line impedance should be
provided in the supply side of the drive.
Refer to”Line Choke Installation Drawings”, page 3-55, for selection details.
