3.2 Uninterruptible Power Supply UPS
WARNING:
The BDS system is designed to connect to UPS systems that are 600VDC or less and a
maximum of 300V with respect to earth ground. The user must verify the voltage with
respect to earth ground before connecting the system. Do this by measuring the voltage
from each battery post referenced to earth ground. The voltage cannot exceed 300V.
If the user is using an optional UPS with the system, be certain the UPS internal battery is
functional. Follow instructions in the UPS manufacturer's manual.
4 Preventive Maintenance
4.1 Visual Inspection
Visually inspect all monitor system components for damaged or frayed power cords and cables,
and damaged component panels, controls, and connectors. When damage is detected, remove
the equipment from service until the damage is repaired.
4.2 Cleaning System Components
Clean system components using a soft cloth, slightly moistened with water. Do not use
commercial or industrial cleaners that may attack the computer display and housing. Never
expose the computer or system components to water, high humidity, or dampness.
WARNING:
Before cleaning equipment, ensure the system is disconnected and power to the units
has been shut off. The user must disconnect system components and the monitor
system cabinet, if a cabinet is being used, from AC and/or DC power sources.
4.3 Fans and Vents
Remove dust from fans and vents using a small brush or hand held vacuum. Immobilize fan
blades to avoid over–speed when using a vacuum.
4.4 Sense Leads (When Applicable)
Before cleaning the sense lead clips, ensure the system is disconnected and power to the
system has been shut off. Clean the sense leads as required. The acid to which the sense lead
clips are exposed during testing must be neutralized often, using a water and baking soda
mixture. Brush this mixture onto the sense lead clip, and then rinse well with clean, cool tap
water. Dry with a clean, soft cloth.
NOTE:
Some equipment and systems may not be equipped with lead clips.
4.5 Internal Components
The monitor system has no user–replaceable components. Since high voltage exists in most
system components, only knowledgeable users should remove the covers or cowling from
components (monitor, UPS, etc.) when required. Failure to comply with this restriction could
pose a safety hazard and/or void the product warranty.
