Ex-Relevant Excerpt from AVENTICS GmbH's Operating Instructions for the
Bus Module C-Design
Preamble
To ensure function and your own safety, carefully read the enclosed operating
instructions before beginning installation. Contact AVENTICS GmbH if you have
any further questions.
General information on explosion protection
The Bus modules convert a bus module protocol into a protocol that can be read out by
valve systems. The electrical supply, the bus module connection and the VDS lines are
provided via plugs with pre-assembled cables which are to be secured accordingly. The
data circuits can - but this is not obligatory - be galvanically isolated; this has no effect on
the explosion protection.
The Bus module may only be used in accordance with the specifications outlined
in the technical documentation from Aventics GmbH and the information on the
product rating plate. They correspond to the valid standards and directives and fulfill the
requirements of the ATEX directive 2014/34/EU. The installation regulations (e.g.
EN 60079-14) for systems in explosive areas must be observed.
The Bus modules can be used as follows:
• In zone 2 (gas-ex, category 3G) in explosion groups IIA and IIB
In the Ex area, 135°C is the reference temperature for determining the temperature
class (T4) and for further considerations with respect to the safety distance from
the smoldering temperature.
• The permissible ambient temperature range is listed in section "Definition of
types" of this chapter.
General requirements
a) The manufacturer is not liable for damages in the case of non-compliance with
these instructions or improper interventions in the device. Furthermore, the
warranty for appliances and accessory parts will no longer apply.
b) Observe the information in these instructions, as well as the operating
conditions and permissible values stated on the labels/rating plates of the
respective devices.
c) Observe the general technical rules for the selection and operation of devices.

interference.
e) The Bus modules are only permitted for appropriate and intended use in
normal industrial settings. In the case of violation, all manufacturer liability and
warranty claims will no longer apply!
f) Ensure that the device is only fitted with ignition protection complying with the
respective zones!
g) All connected electrical devices must be suitable for their respective functions.
h) The operator must provide sufficient lightning protection in accordance with
local regulations.
i) Be aware of electrostatic when assembling the Bus module.
j) Make sure that no falling objects can hit the Bus module.
