The two 5.5 mrn nuts on the heat sink must be tightened to specifications. When reinstalling the
connectorboard, follow this procedure to obtain the correct torque:
1. Install the three screws first.
2. Start one nut on the shaft and tighten it until contact is made.
3. Tighten the nut another one-quarter of a turn.
4. Repeat steps 2 and 3 for the other nut.
CAUTION
DO NOT OVERTIGHTEN THE 5.5 mm NUTS. DOING SO WILL
DAMAGE THE REGULATOR ICS.

2. Unscrew the nut from the grounding connection in front of the receptacle.
