** The seventh character (?) of the switch order number must be replaced with the proper code to indicate desired product nationalization:
“A” – No power cord included
“B” – Includes European “Schuko” power cord common in Austria, Belgium, Finland, France, Germany, The Netherlands, Norway, and Sweden
“C” – Includes power cord commonly used in the United Kingdom and Ireland
“D” – Includes power cord commonly used in Japan
“E” – Includes North American power cord
“F” – Includes Australian power cord, also commonly used in New Zealand and the People’s Republic of China
^ Stack cables are not included with the switches and need to be ordered separately. Stack configuration examples: For a stack of 8 switches, order 7 short
cables and 1 long cable. Follow this method for stack of 3 or more switches. For a stack of two, order two short cables only.
