D1031 series are isolated Intrinsically Safe Associated Apparatus installed into standard EN50022 T35 DIN Rail located in Safe Area/Non Hazardous Locations or Zone 2, Group IIC,
Temperature Classification T4, Class I, Division 2, Groups A, B, C, D, Temperature Code T4 and Class I, Zone 2, Group IIC, IIB, IIA Temperature Code T4 Hazardous Area/Hazardous
Locations (according to EN/IEC60079-15, FM Class No. 3611, CSA-C22.2 No. 213-M1987, CSA-E60079-15) within the specified operating temperature limits Tamb -20 to +60 °C,
and connected to equipment with a maximum limit for AC power supply Um of 250 Vrms.
Non-incendive field wiring is not recognized by the Canadian Electrical Code, installation is permitted in the US only.
For installation of the unit in a Class I, Division 2 or Class I, Zone 2 location, the wiring between the control equipment and the D1031 associated apparatus shall be accomplished
via conduit connections or another acceptable Division 2, Zone 2 wiring method according to the NEC and the CEC.
Not to be connected to control equipment that uses or generates more than 250 Vrms or Vdc with respect to earth ground.
D1031 series must be installed, operated and maintained only by qualified personnel, in accordance to the relevant national/international installation standards
(e.g. IEC/EN60079-14 Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines), BS 5345 Pt4, VDE 165,
ANSI/ISA RP12.06.01 Installation of Intrinsically Safe System for Hazardous (Classified) Locations, National Electrical Code NEC ANSI/NFPA 70 Section 504 and 505,
Canadian Electrical Code CEC) following the established installation rules, particular care shall be given to segregation and clear identification of I.S. conductors from non I.S. ones.
De-energize power source (turn off power supply voltage) before plug or unplug the terminal blocks when installed in Hazardous Area/Hazardous Locations or
unless area is known to be nonhazardous.
Warning: substitution of components may impair Intrinsic Safety and suitability for Division 2, Zone 2.
Explosion Hazard: to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or unless area is known to be nonhazardous.
Failure to properly installation or use of the equipment may risk to damage the unit or severe personal injury.
The unit cannot be repaired by the end user and must be returned to the manufacturer or his authorized representative. Any unauthorized modification must be avoided.

Testing procedure at T-proof
The proof test shall be performed to reveal dangerous faults which are undetected by diagnostic. This means that it is necessary to specify how dangerous undetected fault,
which have been noted during the FMEDA, can be revealed during proof test.
Note for switch input: use of voltage free electrical contacts with fault detection enabled requires, near the switch at the end of the line, a 1 K
Ω
series connected resistor and a 10 K
Ω
parallel connected resistor in order to allow the fault detection circuit to distinguish between a condition of contact close/open and a line open/short circuit fault.
The Proof test
consists of the following steps:
Steps
Action
1
Bypass the Safety PLC or take any other appropriate action to avoid a false trip.
2
Vary the state conditions of the input sensors / contacts coming from field and verify that the relay or transistor outputs change their state from energized to de-
energized and vice-versa; also check that the de-energized state condition corresponds to the required Safety Function.
3
Disconnect the input wiring coming from the field sensor / contact and check that the corresponding alarm output is de-energized.
4
Short the input connections and verify that the corresponding outputs remains de-energized. In both cases, the corresponding alarm LEDs on the front panel must
be turned red.
5
Restore the loop to full operation.
6
Remove the bypass from the safety-related PLC or restore normal operation.
This test will reveal approximately 99 % of possible Dangerous Undetected failures in the repeater.
