earth terminal blocks of the ZPE-Series, (increased safety “eb”):
Application Case
A – Continuous|
---|---
C – Adjacent – separated by an end plate|
D – Intermediate – bridging one or more unconnected terminals|
– Next to a protective conductor terminal (earth) without an end plate|
Information for further cross-connector arrangements will be provided on
request.
Note: If smaller cross sections than the rated cross-section are used,
the belonging lower current has to be laid down in the IECEx/EC-Type
Examination Certificate of the complete apparatus.
Mounting instructions:
The ZDU/ZPE series is suitable for application in enclosures in atmospheres
with flammable gases or combustible dust. For use in flammable gases, these
enclosures must satisfy the requirements according to IEC/EN60079-0 and
IEC/EN60079-7. For use in combustible dust, these enclosures must satisfy the
requirements according to IEC/EN60079-0 and IEC/EN60079-31. Regarding the use
of accessories, the instructions of the manufacturer must be followed.
Schedule of Limitations:
The ZDU/ZPE terminals are suitable for use in enclosures in atmospheres with
flammable gases or combustible dust. For flammable gases, these enclosures
must satisfy the requirements according to IEC/EN60079-0 and IEC/EN60079-7.
For combustible dust, the enclosure must satisfy the requirements according to
IEC/EN60079-0 and IEC/EN60079-31. The terminal blocks shall be placed inside a
suitable IECEx/ATEX/UKCA certified IP54 enclosure for gas atmosphere. For dust
atmosphere, the terminal blocks shall be mounted inside a suitable
IECEx/ATEX/UKCA certified certified ‘t’ enclosure (IEC/EN60079-31). Under
normal operating conditions the temperature rise of the terminal blocks is a
maximum of 40 K, measured at the maximum permitted rated current. Due to the
above-mentioned, the terminal blocks may be used in apparatus of temperature
classes T6..T1 as long as the terminal block ambient temperature range is not
exceeded. No part of a terminal block must exceed 110 °C under any condition.
T6 (- 60°C … +40 °C)
T5 (- 60°C … +55 °C)
T4 (- 60°C … +70 °C)
When using the types ZDU and ZPE especially with other terminal blocks series
or sizes or accessories the requirements for clearance and creepage distances
according to IEC/EN60079-7 must be observed. Regarding the use of covers,
cross-connectors, and end brackets the instructions of the manufacturer must
be followed. For cross connection accessories’ current rating, and resistance
across the terminal please refer to the table under “Technical data” above. No
other wire sizes or types than the ones specified in the instructions must be
used. The terminal blocks must either be mounted next to another block of the
same type and size or with an end plate. If smaller conductor cross sections
than the rated conductor cross sections are used, then the corresponding lower
current shall be stated in the Certificate of the complete apparatus.
– Cross connections with blank ends shall not be used.
– Manually cut cross connections shall not be used.
Essential Health and Safety Requirements:
Concerning ESRs this Schedule verifies compliance with the Annex II of ATEX /
Schedule 1 of UKCA directive and Equipment and Protective Systems Intended for
Use in Potentially Explosive Atmospheres Regulations 2016 only. By placing the
product on the market, the manufacturer declares compliance with other
relevant Directives and all other safety-related requirements including those
of Annex II / Schedule 1 of these Directives.
