300 W Active Shunt Regulator 5
If the work environment dictates, the shunt module should be in an enclosure
providing protection against dust and splashing water (IP54), or dust free and
protection against water jets (IP65).
Many National Electrical Manufacturers Association (NEMA) Type 4 cabinets
provide this level of protection.
Mount the Active Shunt Module
To mount the shunt module on a flat, solid, grounded surface:
1. Install the top mounting fasteners on the subpanel for the shunt module.
Refer to Product Specifications on page 7 for fastener, wire, and terminal
torque specifications.
2. Mount the shunt module on the two fasteners.
3. Install the lower fasteners.
4. Tighten all mounting fasteners.
ATTENTION
Avoid contaminating electronic components.
Provide a quality air source to cabinets: free of
debris, oil, corrosives, or electrically conductive
contaminates. All cabinets should have scheduled
inspections and be cleaned as needed.
Failure to observe these safety procedures could
result in breakdown and damage to equipment.
ATTENTION
If you mount the shunt module inside a cabinet, you
must make sure that the ambient temperature inside
the cabinet does not exceed 40 °C (104 °F). Power
performance must be decreased 5.5 W for every
1.0 °C (3.1 °F) of increasing ambient temperature.
