X1_Hardware_Installation_-_General

Warning

The Telesis X1 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.

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 Telesis X1
  • 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 than 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

The X1 may have AC-DC rectifier units, RPS-48A (ordering code: 2.x1a.urnmps4) and has the following power specifications.

Input (RPS-48A):

  • 180 - 265 VAC at 50Hz
  • 0.95 Amp at 230VAC

Output (RPS-48A):

  • -54 VDC, 4.2 Amp

2.x1a.urnmps4

The X1 may also have two models of DC-DC converter units. The model RPS05A (ordering code: 2.x1g.urnps05) is used in analog and ISDN peripheral racks. It has the following power specifications.

Input (RPS05A):

  • 54 VDC

Output (RPS05A):

  • +5 VDC (3 Amp)
  • -5 VDC (1 Amp)
  • Ring (10w, 25Hz)

2.x1g.urnps05

The model PSPW05 (ordering code: 2.x1g.urnpcps) is used in E1 interfaces racks. It has the following power specifications.

Input (PSPW):

  • 54 VDC

Output (PSPW):

  • +5 VDC (25 Amp)
  • -5 VDC (1 Amp)
  • +12 VDC (8 Amp)
  • -12 VDC (2 Amp)

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.)
The battery to equipment connection should be made with a single connector cable of specified cross sectional area: 0-8m: 4 mm, 8-12m: 6 mm, 12-20m: 10mm
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.
