PX24MrXHardwareInstallationThe Telesis PX24 mrX system (AU) 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:
Ensure that the installation site does not contain:
Power To ensure long operational life to your system and your safety, the 220 VAC outlet that connects to the system AC-DC power supply (i.e., adapter, converter) 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 AC-DC power supply. Input and output power specifications for the PX24 mrX are:

DDL : S0/T0 Basic Rate ISDN Card (Expansion Card for PX24 mrX) Each port can be configured individually as a subscriber S0 or a trunk T0 through jumpers and on it, and appropriate programming. Note that the DDL card can be inserted into the Expansion Slot -3 only. AC-DC Power Converter and Battery Connection Be aware that AC-DC power converter is specially designed for the PX24 mrX. Never use any adapter or power converter except the one supplied by Telesis. Otherwise, you may damage your system. You must always connect the AC-DC power converter to a grounded mains socket. Otherwise your system may not operate properly. The power supply of the Telesis PX24M rev.7 Hybrid IP PBX System may be backed up with batteries. The recommended batteries for a 5-6 hour backup time is 7 AH (Amper Hours), 48V. Using a battery group consisting of four dry, gel, maintenance-free batteries, each with 12Volts 7 AH, may be a good option. For battery to PX24 mrX connection, use the battery connection cable supplied by Telesis. Connect the cable to the battery socket on the front panel. Red terminal on the other end of the cable is connected to the + pole of the battery and blue (or black) terminal is connected to - pole of the battery. Replacing the Fuse Disconnect all power sources (batteries and AC-DC power converter) from the Telesis PX24 mrX system. Unscrew the fuse holder. Replace the broken fuse with a new one (2Amp). Place the new fuse into the fuse holder and screw it. Connect all power sources to the system again. |
