11.1
Preventative Maintenance
This section describes how to perform preventative maintenance on the GridTime 3000 to help reduce the chance of
future faults.
The GridTime 3000 requires minimal preventive maintenance. Ensure the unit is not exposed to hazards
such as direct sunlight, open windows, water, or extreme heat. See
6.1.2.1. Environmental Requirements
, for
electromagnetic compatibility conditions that may cause damage.
CAUTION
To avoid electromagnetic discharge damage to the circuitry, never attempt to vacuum the GridTime 3000.
CAUTION
To avoid damage, under no circumstances should the interior chassis of the GridTime 3000 be allowed to
come in contact with water.
The following table lists preventive maintenance measures to be performed periodically. Do not disassemble
components just for the purpose of inspection.
