Installation
1. Clean the Inverter Heat Sink Plate where the original DC-DC was mounted.
2. Apply additional thermal paste to the DC-DC if it is to be reused.
NOTE
Open Frame DC-DC Converters do not require thermal paste.
3. Install the rear M3x10 fasteners that secure the DC-DC Converter to the Inverter Heat Sink
Plate. Do not tighten at this time; leave enough space under the fasteners to allow the DC-DC
Converter to slide under. Refer to "Figure 4-261 DC-DC Rear Fastener Install".
