8A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If products installed in separate buildings are interconnected, the voltage potential may cause a hazardous condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if necessary, implement corrective action prior to interconnecting the products.

9In addition, if the equipment is to be used with telecommunications circuits, take the following precautions:

—Never install telephone wiring during a lightning storm.

—Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

—Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

—Use caution when installing or modifying telephone lines.

—Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from lightning.

—Do not use the telephone to report a gas leak in the vicinity of the leak.

10CLASS 1 LASER PRODUCT: This product has provisions for the customer to install a Class 1 laser transciever, which provides optical coupling to the telecommunication network. Once a Class 1 laser product is installed, the equipment is to be considered to be a Class 1 Laser Product (Appareil à Laser de Classe 1). The customer is responsible for selecting and installing the laser transciever and for insuring that the Class 1 AEL (Allowable Emission Limit) per EN/IEC 60825 is not exceeded after the laser transponders have been installed. Do not install laser products whose class rating is greater than 1. Refer to all important safety instructions that accompanied the transciever prior to installation. Only laser Class 1 devices, certified for use in the country of installation by the cognizant agency are to be utilized in this product.

11The equipment is intended for installation in a max. 50° C ambient temperature, in an environment that is free of dust and dirt.

12The power supply cord for countries other than North America is to be a minimum H05 V V-F type, min. 0.75 mm2, 2-conductor and earth ground terminated in an IEC 320 connector on one end, and a plug which is certified for use in the country of installation at the other end.

13Do not physically stack more than eight (8) 26x1 units high. Physical stability has not been evaluated for stacking higher than eight units, and any configuration greater than eight may result in an unstable (tip-over) condition. Ensure that the four (4) rubber feet supplied with the product have been installed on the bottom of each unit prior to stacking any 26x1 units on top of one another.
