Marine Use

American Bureau of Shipping (ABS) certification requires flame-retarding insulation as per
4-8-3/5.3.6(a). ABS will accept Navy low smoke cables, cable qualified to NEC "Plenum
rated" (fire resistant level 4), or other similar flammability resistant rated cables. Use cable
specifications for your system that meet a recognized flame retardant standard (i.e. UL, IEEE,
etc.), including evidence of cable test certification (i.e. tests certificate, UL file number, etc.).
NOTE: Wiring needs to be "low smoke" per the above paragraph. Teflon coated wire is also recommended.

Agency Approvals

Some applications require agency approvals. Typical agency approvals which your application
may require are:
• UL (Underwriters' Laboratories, Inc.)
• CSA (Canadian Standards Association)
• FM (Factory Mutual Research Corporation)
• CUL (Canadian Underwriters' Laboratories, Inc.)

24 VDC Power Bases

Follow these additional installation guidelines when installing D2-03BDC1-1, D2-04BDC1-
1, D2-06BDC1-1 and D2-09BDC1-1 bases:
• Install these bases in compliance with the enclosure, mounting, spacing, and segregation
requirements of the ultimate application.
• These bases must be used within their marked ratings.
• These bases are intended to be installed within an enclosure rated at least IP54.
• Provesions should be made to prevent the rated voltage being exceeded by transient disturbances of
more than 40%.
