3. Batteries

The backup batteries supply 48V from 4 12V cells. The batteries are housed in a drawer at the bottomof the cabinet.

Battery life

Depending on customer requirements, there are two types of battery:

- 15Ah providing 4 hour autonomy for a configuration with up to 190 users at 0.25 Erlang

- 38Ah providing 4 hour autonomy for a configuration with up to 500 users at 0.25 Erlang

The 15Ah batteries recharge within 20 hours.

The 38Ah batteries recharge within 22 hours.

4. Battery alarm

When the batteries (with built-in fuse) are almost completely discharged, the voltage drop causes thecabinet to shut down. The PSAL signal triggers shutdown of the system when battery voltage falls belowapproximately 45V. This guarantees a shutdown that damages neither the hardware nor the software.

The PSAL signal is generated by a small board located in the PSAL light. This light is located on thefront panel of the cabinet.

MI Cabinet Section 1 - PresentationHardware description

5. Protective ground

The protective ground must be connected to the MI cabinet by a terminal located on the 48V distributionterminal block.

This terminal enables electrical connection between the ground cable and the metal bracket to whichit is attached.

Electrical continuity is ensured in all metal parts of the MI cabinet by special bolting.

The MI cabinet accepts GN or GG type grounding.

3. PABX installation conditions

3.1. EnvironmentThe PABX is designed to work in a well-ventilated office atmosphere. It has ventilation grills.

3.2. TemperatureIn operating conditions the temperature gradient must not exceed 20 C/hour (68 F/hour).


A L C ET L



During storage, the temperature must be between -5 C (23 F) and 45 C (113 F). The temperaturegradient must not exceed 10 C/hour (50 F/hour).

During hardware transportation, the temperature must be between -13 F and 140 F. The temperaturegradient must not exceed 20 C/hour (68 F/hour).

3.3. Ventilation - Air conditioning

According to the premises chosen and the installation capacity, choose:

- either forced ventilation to avoid the accumulation of hot air close to the PABX,

- or air conditioning.

This air conditioning can be that of the building in which the room is located but certain precautionsmust be taken, such as:

- when the air conditioning is shut off, this must not produce a high rise in temperature,

- planning automatic restoration after mains recovery.

To overcome these problems, use air conditioning which is specific to the premises and powered by aback-up unit.

To ensure that the PABX operates properly, the main precautions to be taken are:

- choosing premises with the most favorable thermal conditions,

- ventilation and air conditioning on back-up unit,

- automatic ventilation and air conditioning restart as soon as the mains power supply has beenrestored,

- thermal alarm installation. In order to remedy an air conditioning system failure quickly, a devicesignaling an unusual temperature rise is necessary.

3.4. Hygrometry

The degree of hygrometry without condensation must be between 8% and 80%. The hygrometric va-riation must not exceed 30% per hour during operation and during transportation and 10% per hourfor storage.

The absolute hygrometry must be between 1g/m3 and 25g/m3.

3.5. Atmospheric pressure

The atmospheric pressure must be between 70 kPa and 106 KPa.

3.6. Radiation

Only radiation sources respecting the prevailing EMC standards can be located near the PABX (pho-tocopiers, transformers, electrical control panels, etc.).

In all cases, the PABX and sets must not be located in an electromagnetic field greater than 3 V/m.


A L C ET L



3.7. Abnormal voltagesNo source of industrial parasites, whether repeated or accidental, electric or electrostatic, no telephoneor computer distribution line exposed to atmospheric disturbances must interfere with PABX operation.

3.8. LightingThe ambient electrical lighting must be sufficient to allow rapid intervention on the equipment. Inaddition, the rear and front panels of the PABX must be sufficiently lit and also the maintenance desk.In line with office premises, the average lighting level must be about 300 lux at 80cm from floor level.Avoid direct sunlight and prefer incandescent lighting or anti-interference fluorescent tubes. The ligh-ting sources must be powered by the back-up network if it exists.

3.9. Vibrations and shocksThe hard disk and diskette drives are the most sensitive to these two phenomena. The vibrations mustnot exceed 0.02 G with double amplitude less than 25 m. The shocks must be less than 0.1 G.

4. Rectifier installation conditions

Note: This paragraph does not apply to the MI cabinet.The rectifier can be located in a specific room or in the same room as the PABX provided that it meetsthe radiation standards and is at least 3 metres from the PABX, to avoid any radiation.If the rectifier is located in separate premises, these premises must meet the following conditions:

- no dust, acid fumes, corrosive atmosphere, different types of ducts (water, gas, electricity),

- temperature and hygrometry in line with the manufacturers standards,

- the power supply cabinet must be installed as near as possible to the rectifier,

- the distance between the rectifier and the PABX must not be too great to avoid oversizing ofthe power supply cables.

The nature, calibration and type of protection devices, emergency stop devices, conductor cross-sectionand type of canalisation must be defined in accordance with prevailing standards.

5. Battery installation condition

Nota: This paragraph does not apply to the MI cabinet.The batteries must be fitted in:

- a dry and well-ventilated room if they are lead-based or CdNi-based batteries,

- the same room as the PABX if they are sealed batteries.According to the type of battery, check the electrolyte level. If the batteries are delivered dry, fill themup with distilled water. It is essential to comply with the scheduled refill operation specified by themanufacturer.


A L C ET L
