4 ClassIfication
Clause 4 of the product standard, in which this document is referred to. applies
5 Characteristics of devices
Clause 5 of the product standard, in which this document is referred to, applies
6 Marking and oth.r product information
In addition to Clause 6 of the product standard, in which this document is referred to. the following markings apply
Universal terminals:
— no marking.
Non-universal terminals
— terminals declared for rlgid solid conductors shall be marked with the letters sol’.
— terminals declared for rigid (sotid and stranded) conductors shall be marked with the letter
— terminals declared for flexible conductors shall be marked with the letter TMf”
The markings shall appear on the device or. lithe space available is not sufficient. on the smallest package unit or en technical information.
An appropriate marking Indicating the length of insulation to be removed before insertion of the conductor into the terminal shall be shown on the product
The manufacturer shall also provide information, in Its literature. on the maximum number of conductors which may be damped
