2.1.3 Windows
Keep all of the windows closed if the location is affected by dust, sea breeze or corrosive
gas. Curtains or blinds are necessary to avoid direct sunlight.
2.1.4 Fire Extinguisher
Place a fire extinguisher for electrical fires (such as a carbon-gas fire extinguisher or a
halon-gas fire extinguisher) near the system. It is recommended that the room also be
equipped with an automatic fire-detection system. In the event of smoke and fire, turn off
the main power source and the backup battery, then use the fire extinguisher to put out
the fire while trying to avoid inhaling any smoke.
2.1.5 Safety Environment
Consider measures to deal with disasters (such as fires, floods and earthquakes) and to
ensure the safety of the staff.
Regularly clean the room or rooms where the switching equipment resides.
Do not spray any insecticides directly on the equipment (insecticides can adversely affect
the switching equipment).
2.1.6 Air Conditioning Facilities
The system and the air conditioning system must be installed separately and have
separate power sources.
To prevent an electromagnetic arc from causing noise, attach a surge-limiting capacitor
and resistor on the air conditioner's electromagnetic switch's coil.
It might be necessary to adjust the ventilation so the air conditioning is equally effective
throughout the equipment room.
Do not place the system in a location where condensation might fall from an air
conditioner or a duct.
Do not place the system in a location where hot and humid air is exhausted, as this might
damage the system.
2.1.7 Lightning Strikes
The grounding system must protect the system, MDF, main power source, PCPro, printer,
modems, etc. from damage caused by lightning strikes and electrical surges.
All the grounding conductors must have a resistance of less than one Ω to bring a
zero-voltage reference to the system components.
To achieve this, the following ground conductors must connect to the Primary Ground
Bar:
･The Earth Ground (E) from the Rectifier
･The Frame Ground (FE) from the system
･The Power Ground (PE) from the system, through the Rectifier
･The Frame Ground (FE) from the MDF
･The AC service outlets, with plug outlets, for the PCPro, printer, modems and any
2.1.8 Electromagnetic Interference
When installing an additional device in the vicinity of the system, observe the installation
and operating instructions for the device.
Otherwise, EMI noise from the device may cause a malfunction of the system.
measurement devices, such as a protocol analyzer.
