RAYCAP Telephone Line Protector
Installation Instructions
IMPORTANT: Please read these instructions carefully. Whilst straightforward, the correct installation of these devices is critical to their performance.
Installation must be performed by a suitably qualified person in accordance with applicable standards.
1. Introduction
1.1 These installation instructions apply to Raycap telephone line surge protectors with the following catalogue numbers: Pt 123.360 (1x MGZ LL/K10 carriage) + Pt 698.011 (10x GDT 230V TK)
Assembled catalogue description MGZ LL/K10 +GDT 230V TK = Pt 123.936.
1.2 This product is designed for installation in KRONE LSA-PROFIL® systems. Each line protector employs single shot 2KA 10/350μs lightning current protection with failsafe and multi-use 8/20μs over volt mode protection to provide quality surge protection for telecommunication equipment. The unit is designed and certified to IEC EN 61643- 21 for telecommunication systems and signalling networks conforming to IEC EN 62305-1 recommendations.
2. Installation
2.1 Ensure the KRONE LSA-PROFIL® plus metallic mounting frame is bonded to earth with a minimum CSA of 4mm insulated copper earth wire.
2.2 Fit the Raycap telephone line surge protector to the LSA plus Krone block ensuring the unit is aligned and pressed firmly into the block with the earth forks at each end of the module connecting to the metallic mounting frame. Check to ensure the module is completely inserted into the block.
There is no wrong way to install the unit in terms of Line side / Equipment side.
3. Once installed
3.1 Check the installation by testing that the equipment is still operating correctly.
3.2 The RAYCAP telephone line surge protector is extremely robust and requires very little maintenance. Each GDT features a failsafe overcurrent protection band. In the event of a surge that is too large the failsafe will operate. This is easily detectable, as the line signal will no longer pass. Under these circumstances the signal line protector should be replaced as soon as possible.
4. Dismounting the module
4.1 When dismounting the module, first check to see if there are signs of damage, melting, heat etc. and that there is no sign of mains voltage incursion onto the telecommunication lines. After doing this the module can simply be pulled out of the LSA plus Krone block. Again care should be taken when removing the module not to dislodge any of the telephone line wiring, should this occur, a Krone insertion tool should be used to re-terminate the dislodged lines before replacing the module.
