D1061
- RS422 / RS485 Fieldbus Isolating Repeater
G.M. International ISM0068-12
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, transmission led should reflect the communication line activity.
Installation
D1061 is a RS232/RS422/RS485 fieldbus isolating repeater housed in a plastic enclosure suitable for installation on T35 DIN Rail according to EN50022.
D1061 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 RS232, RS422 and RS485 serial line connection in Safe Area, a SUB D 9 poles female connector is also provided
(for Zone 2 or Division 2 installations check the area to be nonhazardous before servicing)
.
The wiring cables have to be proportionate in relation 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 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”.
Connect field serial line type RS485 or receiving section of RS422 in Hazardous Area at terminal “13” and “14” corresponding to A- and B+.
In addition when using RS422 serial line, connect transmitting section at terminal “15” and “16” corresponding to A- and B+.
Connect field serial line type RS485 or receiving section of RS422 in Safe Area at terminal “5” and “6” corresponding to A- and B+.
In addition when using RS422 serial line, connect transmitting section at terminal “7” and “8” corresponding to A- and B+.
Safe Area side connection are also available on SUB D 9 poles female connector.
Note:
please pay attention to the serial cable used for Safe Area connection. The internal wiring of the cable must be straight.
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,
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), make sure that conductors are well isolated from each other and do not produce any unintentional connection.
The wiring between the Intrinsically Safe Equipment located in Hazardous Area/Hazardous Locations and the D1061 Associated Apparatus must have a minimum insulation
thickness of 0.25 mm.
The enclosure provides, according to EN60529, an IP20 minimum degree of mechanical protection (or similar to NEMA Standard 250 type 1) for indoor installation, outdoor installation
requires an additional enclosure with higher degree of protection (i.e. IP54 to IP65 or NEMA type 12-13) 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 D1061 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, D1061 series must be connected to SELV or SELV-E supplies.
