6/ CONNECTION (switch unpowered)
The equipment connected to the switches is certified intrinsically
safe for the ATEX group corresponding to the use of the switches
according to the input specifications mentioned hereafter.
On red wires (detection part of supports)
- Group I : Ui = 24V AC or DC ; Li= 400 mA ; Pi = 3,15 W ; Ci = 4,3 nF ; Li = 0 µH
- Group II : Ui = 24V AC or DC ; Li =400 mA ; Pi = 1,2 W ; Ci = 4,3 nF ; Li = 0 µH
On the yellow wire (+VLED) compared to blue wire (GROUND) (lighting part)
- Group I : Ui = 24V AC or DC ; Li = 400 mA ; Pi = 3,15 W ; Ci = 0 nF ; Li = 0 µH
- Group II : Ui = 24V AC or DC ; Li = 400 mA ; Pi = 1,2 W ; Ci = 0 nF ; Li = 0 µH
Instruction Notice n°NTPBA007-V04-ENG
The switches shall be connected to ground with the appropriate ground connector and wire
length between switch and operated part shall no exceed 10m. This will ensure EMC according
to the EN61058-1 standard.
7/ ADJUSTMENT
: the switches do not require any adjustment
8/ BRINGING INTO SERVICE
Bringing into service will be made after approval by the project manager, on the base of the reports issued by
the installation engineer or any person entitled to verify the conformity of ATEX installations.
