Table 8 provides the acoustic noise levels for the QS1200 and QS2400 base system.
QS1200/QS2400 Base System Site Wiring and Power
This section provides site wiring and power information for the QS1200 and QS2400 base systems.
Site Wiring
The QS1200 and QS2400 base systems use wide-ranging, redundant power supplies that
automatically accommodate voltages to the AC power source. The power supplies meet standard
voltage requirements for both North American (USA and Canada) operation and worldwide (except
USA and Canada) operation. The power supplies use standard industrial wiring with line-to-neutral or
line-to-line power connections.
Keep this information in mind when you prepare the installation site for the QS1200 and QS2400
base systems:
• Protective ground – Site wiring must include a protective ground connection to the AC power
source.
NOTE: Protective ground is also known as safety ground or chassis ground.
• Circuit overloading – Power circuits and associated circuit breakers must provide enough power
and overload protection.
NOTE: To prevent damage to the base system, isolate its power source from large switching loads,
such as air-conditioning motors, elevator motors, and factory loads.
• Power interruptions – The base system can withstand these applied voltage interruptions:
• Input transient – 50 percent of the nominal voltage
• Duration – One half-cycle
• Frequency – Once every 10 seconds
• Power failures – If a total power failure occurs, the base system automatically performs a
power-on recovery sequence without operator intervention.
