TPRF31 Installation
The TPRN kit provides:
• 1 TPRF31 sub-rack
• 1 power supply cable
• 1 standard RS232 cable (male-female)
• 3 Alarm-output connectors
• 3 Auxiliary input connectors
• 1 Cd-rom, including ION-B manuals and tools
The TPRF31 Fast MiniRack is provided with some
reversible brackets and suitable both for rack-
mounting and for wall-mounting.
Straight from the factory, the TPRF31 has brackets for
rack-mounting which cannot be removed for wall
mounting (see fi gure 4.2.9).
Warning (recommended when designing or installing)
Providing correct heat dissipation
For correct use of the TPRF31 sub-rack, it is important to verify if:
• the TPRF31 has been mounted in a vertical position (please refer to the “TPRF31
Installation” section), the power supplying ports (located on the TPRF31, front side, Figure
4.2.7) have been turned upwards
• the TPRF31 has been mounted on a rack (please refer to the “TPRF31 Installation”
section), a minimum distance of 1 HE has to be kept between nearby TPRN sub-racks to
ensure proper heat dissipation. The rack containing the TPRN sub-racks has to be large
enough to guarantee this correct distance between Master Units.
Setting the dip-switches in a multi sub-rack system
If you are installing a multi-sub-rack system, remember to assign each sub-rack an exclusive
binary address, by properly setting dip-switches 1, 2, 3, 4, 5 on the TPRF31 backplane (see
Fig. 4.2.6 and Table 4.2.3). Dip-switch 5 has to be set on each TPRN sub-rack in order to fi x
the baud rate for the RS485 and RS232 ports. Connecting the TPRNs through the RS485 port is
necessary when supervising the whole multi sub-rack system through the remote supervision
unit (to be set at the same baud rate).
