• The presence of the heating cables shall be made evident
by the posting of warning labels or caution labels (“Electric
Traced”) on the cladding. Labels are to be applied at
maximum 3 meter intervals and on alternate locations along
the circuit.
• Install “Electric Traced” signs along piping at suitable
intervals
(3 m intervals recommended) on alternate sides as a
warning.
• Mark on outside of insulation the location of heating cable
components.
• For XTV, KTV and HTV heating cables if T-class compliance
was proven by stabilized design: install LAB-EX-XTV-KTV
aluminium tag at approximately 75 mm from the entry of the
junction box.
