PX24X_Hardware_Installation

Warning

The Telesis PX24X Hybrid IP PBX System should be installed and serviced only by qualified personnel who has the necessary training about electrical equipment, and who understands the hazards that can arise when working on this type of equipment. PX24X systems (even they may be supported with UPS) must always be operated with batteries connected.

Finding Suitable Place for Installation

The installation site should be bright enough for ease of operation to the maintenance personnel. The site should have enough space. The system should be installed in a room where there is not too much occupancy. Finding a quite location for the operators telephone will reduce occupational strain on the working operator. Batteries that are connected to the system should be in a well ventilated area not too far away from the system. The 220 VAC mains connection should be grounded, the power should not be interrupted except for power outages. The ambient environmental conditions should be within the range of:

  • Temperature range: 0-40 C
  • Humidity range: %0-85 (non-condensing)

Ensure that the installation site does not contain:

  • High voltage lines, smoke, dust, gas or radiation (such as a generator, photocopier etc.)
  • Radio equipment that generates or emits high level signals
  • Sever, pipes, or valves that could leak or cause condensation
  • Vibration causing equipment
  • Exposure heat sources or direct sunlight

Grounding

To ensure long operational life to your system and your safety, all electrical components should be suitably grounded.

  • A protective, independent ground terminal should be connected to the system
  • The resistance of the ground and neutral terminals should not exceed 0.5 ohm
  • The 220 VAC outlet that connects to the system power supply unit should provide phase-ground and phase-neutral voltage difference no more that 5V
  • Any auxiliary equipment that is connected to the system (such as a printer or a maintenance PC terminal) should use the same ground of the system

Power Specifications

Input and output power specifications for a single cabinet of the system are:

Input:

  • 180 - 260 VAC (0.4 Amp at 230VAC)
  • 45 - 54 VDC(1.3 Amp at 48VDC)

Output:

  • +5VDC (3 Amp)
  • -5VDC (0.3 Amp)
  • -54VDC (1.1 Amp)
  • +9 VDC (0.4 Amp)
  • Ring (2w, 25Hz)

Be aware

This system should be installed and serviced only by qualified personnel who has the necessary training about electrical equipment, and who understands the hazards that can arise when working on this type of equipment.
The AC-DC power converter needs to be connected a grounded mains socket.
External lines or outside lines that could be exposed to environmental conditions should be protected with secondary protective circuitry.
The MDF should be grounded. This ground should not be connected to the ground terminal of any other equipment (such as lightning ground, electrical transformer ground etc.)
PX24X systems (even they may be supported with UPS) must always be operated with batteries connected.
The battery to system connection should be made with a special cable supplied by Telesis.
To minimize the risk of electrostatic damage to the system, serviceman should discharge of electrostatic buildup by wearing a shielded bracelet or take other necessary before handling electrostatic sensitive parts such as cards.
This system is to be used in controlled environments where humidity and ambient temperature is maintained within working specifications and necessary precautions should be taken before leaving the equipment un-attendant.
Disconnect all power sources from the system before servicing.
Do not remove or install cards to the system when it is powered up.
Attach all covers in place after servicing system and before leaving the customer premises to avoid customer contact with damageable components.
Any auxiliary equipment that is connected to the system should be set up according to its installation guide.

The Power Supply Unit

The PX24X is equipped with a power supply unit (ordering code 2.px0.psudurn) that takes power from a 220VAC 50Hz wall power outlet. For the basic operation, simply plugging in the power cord to an outlet is sufficient. The power supply is installed in the leftmost part of the main and auxiliary cabinets by pushing the power supply unit through the guides, screwing it securely in place and attaching the ground and 9 pin connectors to the backplane card.

Furthermore, PX24X systems (even they may be supported with UPS) must always be operated with batteries connected.

Connecting the Auxiliary Cabinets

For a multi cabinet PX24X setup, 40-pin connectors on the DFF card are connected to the backplane cards of the auxiliary cabinets with the supplied flat ribbon cables. The first auxiliary cabinet should be connected to the highest connector on the DFF card, the second auxiliary cabinet should be connected to the middle connector on the DFF card, and the third auxiliary cabinet should be connected to the lowest connector on the DFF card by using the appropriate length cables.

A 40 cm long 40-conductor flat cable (ordering code 1.kbl.flt4040) to connect the first auxiliary cabinet to the main cabinet

An 85 cm long 40-conductor flat cable (ordering code 1.kbl.flt4085) to connect the second auxiliary cabinet to the main cabinet

A 110 cm long 40-conductor flat cable (ordering code 1.kbl.flt4110) to connect the second auxiliary cabinet to the main cabinet
