AccuLoad IV Installation & Maintenance Manual “Warning: Clean display with a damp cloth only.” This is to ensure that stray static charges are not built up on the surface that could lead to a static discharge. • Special care must be taken with shielding termination to ensure signal integrity. See Section 3.1: General Electrical Installation Requirements for more information. -
Page 18: Pre-Installation Considerations
In areas of high humidity (tropical) or with varying temperature swings, it is recommended to place desiccant packs (TechnipFMC part number 647001443) inside of the enclosures, and to maintain these while in service. -
Page 19: Electrical Installation Considerations
AccuLoad IV Installation & Maintenance Manual • A solid bracket (rear- or bottom-mount) should be used to support the AccuLoad. Refer to the AccuLoad IV specifications (SS06200) for the weight and mounting dimensions. • The location and the height of the AccuLoad should easily permit operation of the front touch screen and allow for a near-perpendicular viewing angle to minimize parallax effects. - Page 20 AccuLoad IV Installation & Maintenance Manual • Two separate AC circuits must be provided from the breaker panel. One circuit should supply isolated power to the AccuLoad’s electronics (instrument power). The second circuit should supply power to external devices (Section 3.6.1: AC Input Power).
