Warning
Installation
Start-up
D6003 series are electrical apparatus installed into customized Termination Boards located in Safe Area or Zone 2, Group IIC, Temperature T4 Hazardous Area within the specified
operating temperature limits Tamb
‑
40 to +70 °C.
D6003 series must be installed, operated and maintained only by qualified personnel, 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)), following the established installation rules.
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 suitability for Zone 2/Division 2. Avertissement: la substitution des composants peut nuire à l’aptitude à la Zone 2/Div. 2.
Explosion Hazard: to prevent ignition of flammable atmospheres, disconnect power before servicing or unless area is known to be nonhazardous. Danger d'Explosion: pour
éviter l’inflammation d’atmosphères inflammables, débrancher l’alimentation avant l’entretien ou à moins que région est connue pour être non dangereux.
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
D6003 series are relay output module housed in a plastic enclosure suitable for installation on customized Termination Board.
D6003 series can be mounted with any orientation over the entire ambient temperature range.
Electrical connections 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)
. Connect only one individual conductor per each clamping point, use conductors up to 2.5 mm²
(13 AWG) and a torque value of 0.5
‑
0.6 Nm. Use only cables that are suitable for a temperature of at least 85°C.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.
Installation and wiring must be in accordance to the relevant national/international installation standards (e.g. EN/IEC60079

Part
14: Electrical installations in hazardous areas (other than mines)), make sure that conductors are well isolated from each other and do not produce any unintentional connection.
Connect load relay contacts checking the load rating to be within the contact maximum rating (3 A 30 Vdc 90 W resistive load).
To prevent relay contacts from damaging, connect an external protection (fuse or similar), chosen according to the relay breaking capacity diagram from installation
instructions.
The enclosure provides, according to EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). The unit shall be installed in an area of no more than
pollution degree 2 according to EN/IEC60664
‑
1. When installed in EU Zone 2, the unit shall be mounted in a certified Ex enclosure that provides a degree of protection not less than
IP54 in accordance with EN/IEC60079-15. When installed in a Class I, Division 2 Hazardous Location, the unit shall be mounted in a supplemental enclosure that provides a degree of
protection not less than IP54. The enclosure must have a door or cover accessible only by the use of a tool. The end user is responsible to ensure that the operating temperature of the
module is not exceeded in the end use application.
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 D6003 series 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 modification must be avoided.
All circuits connected to D6003 series must comply with the overvoltage category II (or better) according to EN/IEC60664
‑
1.
Before powering the unit check that all wires are properly connected, particularly input and output wires. Check conductors for exposed wires that could touch each other causing
dangerous unwanted shorts.
Enabling input, the “RELAY STATUS” yellow led must be lit and Out 1 circuit must be energized, while Out 2 circuit must be de-energized.
Indeed, disabling input, the “RELAY STATUS” yellow led must be turned off and Out 1 circuit must be de-energized, while Out 2 circuit must be energized.
Operation
D6003 series relay module is suitable for the switching of circuits, without providing isolation between the input and output contacts.
D6003 series provides a NO contacts for normally energized load and a NC contact for normally de-energized load.
A “RELAY STATUS” yellow led lights when input is powered, showing that relay is energized.
