8 D1010-046 - Repeater Power Supply Smart-Hart compatible G.M. International ISM0066-8
D1010-046 series are isolated Intrinsically Safe Associated Apparatus installed into standard EN50022 T35 DIN Rail located in Safe Area or Zone 2, Group IIC, Temperature
Classification T4 Hazardous Area (according to EN/IEC60079-15) 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.
Not to be connected to control equipment that uses or generates more than 250 Vrms or Vdc with respect to earth ground.
D1010-046 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)
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 or unless area is known to be nonhazardous.
Warning: substitution of components may impair Intrinsic Safety and suitability for, 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.

Operation
D1010-046 provides fully floating DC supply for energizing 2 wire 4-20 mA transmitters, or separately powered 3, 4 wire, 0/4-20 mA transmitters located in Hazardous Area, and repeats
and converts the current to a 0/4-20 mA or 0/1-5 V floating output signal to drive a Safe Area load.
The circuit allows bi-directional communication signal for smart transmitters, a “POWER ON” green led lits when input power is present.
Installation
D1010-046 are repeater power supply smart/hart compatible housed in a plastic enclosure suitable for installation on T35 DIN Rail according to EN50022.
D1010-046 unit can be mounted with any orientation over the entire ambient temperature range, see section “Installation in Cabinet” and "Installation of Electronic Equipments in Cabinet"
Instruction Manual D1000 series for detailed instructions.
Electrical connection of conductors up to 2.5 mm² are accommodated by polarized plug-in removable screw terminal blocks which can be plugged in/out into a powered unit
without suffering or causing any damage (for Zone 2 installations check the area to be nonhazardous before servicing).
The wiring cables have to be proportionate in base to the current and the length of the cable.
On the section “Function Diagram” and enclosure side a block diagram identifies all connections and configuration DIP switches.
Identify the number of channels of the specific card (e.g. D1010S-046 is a single channel model and D1010D-046 is a dual channel model), the function and location of each connection
terminal using the wiring diagram on the corresponding section, as an example:
Connect 24 Vdc power supply positive at terminal “3” and negative at terminal “4”.
For Model D1010S-046 connect positive output of channel 1 (mA source mode) at terminal “1” and negative output at “2”.
For Model D1010D-046 in addition to channel 1 connections above, connect positive output of channel 2 at terminal “5” and negative output at “6”.
For Model D1010S-046, in case of a 2 wire Transmitter, connect the wires at terminal “14” for positive and “15” for negative.
For separately powered Transmitters connect input signal at terminal “15” for positive and “16” for negative.
For Model D1010D-046 in addition to channel 1 connections above, connect terminal “10” for positive and “11” for negative on channel 2.
Connect input signal from separately powered Transmitters at terminals “11” for positive and “12” for negative channel 2.
Intrinsically Safe conductors must be identified and segregated from non I.S. and wired in accordance to the relevant national/international installation standards
(e.g. EN/IEC60079-14 Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines), BS 5345 Pt4, VDE 165),
make sure that conductors are well isolated from each other and do not produce any unintentional connection.
The enclosure provides, according to EN60529, an IP20 minimum degree of mechanical protection for indoor installation, outdoor installation requires an additional enclosure with
higher degree of protection (i.e. IP54 to IP65) consistent with the effective operating environment of the specific installation.
Units must be protected against dirt, dust, extreme mechanical (e.g. vibration, impact and shock) and thermal stress, and casual contacts.
If enclosure needs to be cleaned use only a cloth lightly moistened by a mixture of detergent in water.
Electrostatic Hazard: to avoid electrostatic hazard, the enclosure of D1010-046 must be cleaned only with a damp or antistatic cloth.
Any penetration of cleaning liquid must be avoided to prevent damage to the unit. Any unauthorized card modification must be avoided.
According to EN61010, D1010-046 series must be connected to SELV or SELV-E supplies.
Start-up
Before powering the unit check that all wires are properly connected, particularly supply conductors and their polarity, input and output wires, also check that Intrinsically Safe conductors
and cable trays are segregated (no direct contacts with other non I.S. conductors) and identified either by color coding, preferably blue, or by marking.
Check conductors for exposed wires that could touch each other causing dangerous unwanted shorts.
Turn on power, the “power on” green led must be lit, for 2 wire transmitter connection the supply voltage on each channel must be 14 V, output signal should be corresponding to the
input from the transmitter. If possible change the transmitter output and check the corresponding Safe Area output.
