• Alternative charging and communication cable assemblies types “power cable”, “communication
cable”, “power and communication cable”, “vehicle power cable”, ”cradle power and
communications” and “cradle charger“ are suitable for use with T4.
• Refer to Power & Communication Cables Technical Data” manual (M07996) for further details.
• These devices are intended for use in normal atmospheric conditions of temperature –20 °C
to +55 °C; pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and air with normal oxygen content,
typically 21 % v/v (volume/volume).
• T4 ‘Type 2’ (as indicated on the certication label) may be used in Zones 1 and 2, for Group
llA, llB and llC gases and vapours and for Temperature Classes T1, T2, T3 and T4. (see
Certication label below).
Certication label
The certication marking is as follows:
• T4 is certied for use in ambient temperatures in the range -20°C to +55°C (-4 to 131°F).
