001 Stand Alone Low Voltage - Garney Construction

18 Section 3: Application Guidelines
3.6.3 Shock and Vibration
Excessive shock or vibration may cause damage to solid-state equipment.
Special mounting provisions may be required to minimize damage.
Comments: 3.6.3 — Shock and Vibration
Solid-state systems usually have good resistance to shock and vibration
since they contain no moving parts. However, at relatively high levels of
shock or vibration, circuit boards may disengage from mating connectors
if not restrained sufficiently. Circuit boards can crack, components can
come out of sockets or component leads can break loose from a solder
connection to the board. Mounting position is usually of little significance
to solid-state devices except in instances where air flow is required for
cooling.
3.7 The Need for Education -
Knowledge Leads to Safety
Planning for an effective solid-state circuit requires enough knowledge to
make basic decisions that will render the system safe as well as effective.
Everyone who works with a solid-state control should be educated in its
capabilities and limitations. This includes in-plant installers, operators,
service personnel, and system designers.
