 |
| Usage and Installation |
It is used in the telephone-machine, fax-machine, DDN, ISDN special line, computer interface, remote signal line and the defence thunder protective device on the self-controlling line.
The meticulous design enables convenient installation.
The device which is fixed by 35 mm electric rail is connected to the input return circuit of the equipment. The equipment with many return circuits should adopt several group installation, and also can choose XXL-JZ series signal defence thunder case. After its installation, well earthing should be paid attention.
Bounding installation: Bounding installation with many return circuit can installed SPD compactly according to the need of user.
