Preventive Maintenance8. Preventive MaintenanceVisual Inspection - Visually inspect all BVM system components for damaged or frayed powercords and cables, and damaged panels, controls, and connectors. If you detect any damage,remove the equipment from service until the damage is repaired.WARNING: Before cleaning equipment, ensure the system is disconnected and power to the unithas been shut off. You must disconnect the BVM system components from any DC voltagesources and from any AC power sources.Cleaning System Components - When necessary, clean the exterior of the BVM using a softcloth, slightly moistened with water. Do not use commercial or industrial cleaners that may attackthe housing. Never expose any system component to water, high humidity or dampness.Vents - Remove dust from vents using a small brush or hand held vacuum. If vents have dustfilters, clean the filters according to manufacturer's instructions.Sense Leads - Clean the sense leads as required. The acid to which the sense lead clips areexposed during testing should be neutralized often, using a water and baking soda mixture. Brushthis mixture onto the sense lead clip, then rinse well with clean, cool tap water. Before cleaningthe sense lead clips, ensure the system is disconnected and power to the system has been shut off.Dry with a clean, soft cloth.Internal Components - The BVM system has no user-replaceable components. Because highvoltage exists in several areas in the unit, only knowledgeable users should remove the coverwhen required. Failure to comply with this restriction could pose a safety hazard and/or void thesystem warranty.WARNING: High voltages exist inside the BVM system components and on the terminals.Calibration must be performed only by technically qualified persons. Observe electrical safetyprecautions when removing and installing equipment covers and when connecting leads andmaking adjustments.Shipping - Protect the BVM system from bumps and bangs during normal use or storage, andprovide protection during shipment between test sites.10
