Electrical Connection

2.1

General

Channel 1 must always be connected, while channel 2 may by connected only if required.
According the ordering guide in datasheet, assign to channel 1 the most relevant measurand
parameter.
It is essential that installation, electrical connection, commissioning, operation and maintenance in
explosion hazard areas are only carried out by trained, specialized staff, authorised to do so by the
system operator.
For installation in an explosion hazard area, it is essential to ensure that all relevant standards are
observed. The standards EN60079-14, EN60079-25 or IEC60079-14, IEC60079-25 apply for
installation, while EN60079-17 or IEC60079-17 and EN60079-19 or IEC60079-19 for repair and main-
tenance. All relevant national and local regulations shall be observed as well.
The EE100Ex is a 2-wire, loop powered measurement device. Both current outputs are galvanic
isolated.
EE100Ex complies with the requirements of EN60079-11 chapter 6.3.13. It is 500 V voltage proofed
between the electrical circuits of CH1 and CH2 and both circuits to the enclosure.
The free ends of the connection cables shall be fitted with appropriate end sleeves. The distance bet-
ween the two leads of an output channel when fixed into terminals must be at least 2 mm (0.08"). The
distance between the wire-ends from channel 1 and channel 2 must be at least 6mm (0.2").
Changes to the probe cable of model T3 are not permitted. The E+E cable must be used for model T23
2.2

Connecting Cable

The connection cable between EE100EX and the intrinsically safe power supply or zener barriers must
comply with the requirements of IEC/EN60079-14, IEC/EN60079-25 for IECEx and ATEX:
• Maximum cross-section 1.5mm² (0.02 sq.in.)
• Single stranded wire diameter: ≥ 0.1mm (0.004")
• Test voltage wire-wire: ≥ 500V AC eff.
• Test voltage wire-shield (for shielded cable): ≥ 500V AC eff.
• Cable inductivity, cable capacity and conductor resistance are to be evaluated
with respect to intrinsic safety
• Flame-resistant acc. to IEC60332-1-2
Example of connection cable which meets these requirements:

ÖLFLEX® EB CY manufactured by LAPP KABEL.
Additional requirements if both channels (CH1, CH2) are connected using a single cable with 4
leads:
• The test voltage wire-wire ≥ 1000V AC eff.
• Radial thickness of the insulation ≥ 0.2mm (0.008").
• The nominal voltage must be 500V AC eff.
