IR 1403079:
During the Seismic Walkdowns it was identified that there are three screws missing (two on the right side and one on the left side) and I screw loose (on the left side) of the 250VDC Charger. Based on Engineering Judgment the significant number of remaining screws per side are adequate to maintain the connection of the panel during a seismic event, thus preventing any adverse, impact to the charger or surrounding equipment.
Comments SEWS Anchorage Notes:
Angles are welded to the base channel to accommodate anchorage. There are three angle tabs welded to the base channel on each side of the charger. Each angle tab is bolted to the floor with a 3/8" dia. expansion anchor.
