• The S-Series torque wrench is generally
not considered as a potential source of
ignition. However, proper operation and
maintenance of the tool is essential in
order to help ensure that no sparks are
generated that could cause an ignition of
an explosive gas or dust mixture (which
might be present in the environment).
Complete operation and maintenance
instructions must be provided to all
personnel in advance of operating or
servicing the wrench.
• Hot surfaces can be a major source of
ignition. To help prevent the possibility of
ignition resulting from excessive surface
temperatures, do not use the wrench
in an environment with an ambient
temperature of above 104°F [40°C].
• Enerpac has designed and constructed
the S-Series torque wrench to minimize
the possibility of an incendive spark
that may be caused by the impact of
aluminum components with corroded
steel. However, to reduce the chance
of an incendive spark, use of the
wrench with corroded steel structures
or components should be avoided
whenever possible. Be especially careful
to avoid accidental impacts with the
wrench and corroded steel.
NOTICE
To help prevent a mechanical
spark hazard, no components containing a
magnesium content greater than 7.5
percent have been used in the S-Series
torque wrench (in accordance with
standard EN 13463-1).
Use of Torque Wrenches in Explosive
Atmospheres
In addition to the CE mark, the Enerpac
S-Series torque wrenches carry the ATEX
mark and classification:
• S1500X • S3000X • S6000X
• S11000X • S25000X
CE Ex II 2 GD cT4
This classification indicates that the tool is
appropriate for use in a potentially
explosive atmosphere.
The testing standards applicable to
the S-Series torque wrenches are the
standard EN 13463-1:2009, Non-electrical
equipment for use in potentially explosive
atmospheres. Part 1: Basic method and
requirements, and also the draft standard
of ISO/IEC 80079-36.
Contact Enerpac if there are any questions
regarding the ATEX classification or
questions regarding application of the
S-Series torque wrenches in hazardous
environments.
Reducing the Risk of Explosion
WARNING
Failure to observe and comply with the
following precautions and instructions
could result in explosion and/or fire.
Death and/or serious personal injury
could occur.
• To help reduce the risk of explosion,
be certain to use the S-Series torque
wrench only in the specific explosive
atmospheres for which it has been
tested and certified. Refer to the
beginning of this section for ATEX
classification information.
