  • Page 15: Maintenance

    MAINTENANCE Check cable-entry seals periodically. Tighten and/or apply sealant if needed. This is especially important in environments containing heavy concentrations of dust, oil mist, or other residue. Check all wiring connections occasionally for oxidation or corrosion. Clean and re- seat if such conditions are noted. If necessary, check and re-seat any connections that may have been subjected to strain (during rework or construction, for example).
