SCHEDULE OF LIMITATIONS:

The initiator/actuator terminal blocks of the A-series 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 EN 60079-0 and EN 60079-7. For combustible dust

the enclosure must satisfy the requirements according to EN 60079-0 and EN 60079-31.

The enclosure shall be constructed to block all sun and UV light from affecting the terminal blocks. The terminal blocks shall be placed inside

a suitable certified IP54 enclosure in type of protection “e” for gas atmosphere. For dust atmosphere the terminal blocks shall be mounted

inside a suitable certified enclosure (EN60079-31) in type of protection “t”.

Under normal operating conditions the temperature rise of the terminal blocks is maximum 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 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 the initiator/actuator terminal blocks of the A-series especially with other terminal blocks series or sizes or accessories the

requirements for clearance and creepage distances according to table 1 of EN 60079-7 must be observed. Regarding the use of covers,

cross-connectors and end brackets the instructions of the manufacturer must be followed.
