6. Attach the cover to the compartment.

When the Expansion Data Memory Unit is mounted to the CPU, the Expansion

Data Memory Unit is backed up by the battery in the CPU.

When the Unit has been removed from the CPU, the memory contents will be

retained for about 10 minutes by a backup capacitor built-in to the Unit, provided

that CPU power was ON and that the Unit was mounted in the CPU for at least 1

minute.

When removing the Expansion Data Memory Unit, be sure to turn ON the power

to the PC for more than 1 minute and then turn it OFF. At that time the capacitor

will be fully charged allowing it to be backed up for 10 minutes. The retention

period will be shorter if Memory Unit has been mounted (to the CPU) for less

than 1 minute.

Installation Environment

This section details the necessary environmental conditions for installing the

PC.

Caution

Static electricity can damage PC components. Your body can carry an electro-

static charge, especially when the humidity is low. Before touching the PC, be

sure to first touch a grounded metallic object, such as a metal water pipe, in order

to discharge any static build-up.

Ambient Conditions

Do not install the PC in any of the following locations. Doing so will affect PC life

and may affect operating performance.

• Locations subject to ambient temperatures lower than 0°C or higher than

°C.

• Locations subject to drastic temperature changes or condensation.

• Locations subject to ambient humidity lower than 10% or higher than 90%.

• Locations subject to corrosive or flammable gases.

• Locations subject to excessive dust (especially iron dust) or chloride.

• Locations that would subject the CPU to direct shock or vibration.

• Locations that would subject the PC to water, oil, or chemical reagents.

• Locations exposed to direct sunlight.

Cooling

There are two points to consider in order to ensure that the PC does not over-

heat. The first is the clearance between the Racks, and the second is installation

of a cooling fan.
