The E-Stop Safety Module must be installed inside an enclosure. It is not designed for
exposed wiring. It is the user’s responsibility to house the Safety Module in an enclosure
with NEMA 3 (IEC IP54) rating, or better.
Dimensions of the Safety Module are shown in the diagram on page 10. The Safety Module
mounts directly to standard 35 mm DIN rail.
Heat Dissipation Considerations
For reliable operation, the user must ensure that the operating specifications are not
exceeded. The enclosure must provide adequate heat dissipation, so that the air closely
surrounding the Module does not exceed the maximum operating temperature stated in
the Specifications (page 11). Methods to reduce heat build-up include venting, forced
airflow (e.g., exhaust fans), adequate enclosure exterior surface area, and spacing between
modules and other sources of heat.
It is not possible to give exact wiring instructions for a device such as an E-Stop Safety
Module which interfaces to a multitude of machine control configurations. The following
guidelines are general in nature.
The ES-FA-9AA Module has no delay function. Its output relay contacts open within 25
milliseconds after an E-stop switch contact opens. This classifies these E-Stop Safety
Modules as functional “Category 0” E-stop controls, as defined by NFPA 79 (National
Fire Protection Association Standard for Industrial Machinery) and IEC/EN60204-1
(European Standard: “Safety of Machinery, Emergency Stop Equipment, Functional Aspects
– Principles of Design”).
Connect the poles of the E-stop switches as shown in Figures 2 and 3. The switches
are shown in the “armed” position with both contacts closed. Multiple E-stop switches
connected to one E-Stop Safety Module must be series connected (see Figure 4 and the
warning on page 8).
The ES-FA-9AA may be used as a safety gate monitoring module. To achieve Category
4 operation per ISO 13849-1 (EN954-1), two positive-opening safety switches operate
concurrently when the gate or guard is opened (see Figure 5).
The Safety Modules verify concurrent opening of two contacts – one from each safety
switch. Reset of the Safety Modules is not possible if one switch fails to open, or if a short
circuit between the safety switches occurs.
