I Introduction
After removing the unit from its packaging and ensuring that it has suffered no damage in shipment, it
is important to read this manual and follow its instructions to ensure proper connection and mounting.
711HS Series models are fully isolated dc-dc converters capable of delivering up to 720 Watts in
extreme ambient temperatures and adverse operating conditions. See specification sheets at the end
of this manual for the ratings of a particular model.
II Installation
2.1 Mounting
The converters are designed to be mounted to flat metal surfaces offering optimum heat transfer from
the converter base in environments where air flow may be restricted. For best results, thermal
transfer compound is a recommended interface between the converter and mounting surface. The [4]
mounting slots in the flanges will accommodate mounting hardware up to ¼ inch diameter. (See
figure #2 for mounting centers)
