E-Stop Safety Modules with Adjustable Delay –
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 E-Stop Safety Module in an
enclosure with NEMA 3 or IEC IP54 rating, or better.
Dimensions of the Safety Module are shown in Figure 8, page 16. 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 15). 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.
Models ES-TN-14H5 and -14H6 have four redundant immediate normally open supply
output contacts (13-14, 23-24, 33-34 and 43-44), as well as four redundant delayed
contacts (57-58, 67-68, 77-78 and 87-88). This qualifies this E-Stop Module to be
used in applications as a functional stop Category 0 or 1 E-Stop Control as defined by
NFPA 79 and ISO 13850 (EN418).
NOTE: As the normally open immediate and delayed output contacts come from
physically separate relays, a fault could cause only one set of contacts (either the
immediate or the delayed) to close after a manual or auto reset. This possibility
must be considered in the design of the machine control circuit.
Connection of E-Stop Switch
Connect the poles of the E-Stop switch as shown in Figure 3. The switch in Figure 3
is 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 2 and
the warning at right).

CAUTION. . .
Shock Hazard
Always disconnect power
from the E-stop Safety
Module and all power from the machine
being controlled before making any
wire connections.
Electrical installation and wiring must be
made by qualified personnel and must
comply with the NEC (National Electrical
Code), EN60204-1 and -2, and all
applicable local standards and codes.

WARNING . . .
!
Multiple E-Stop Switches
Whenever two or more E-stop switches
are connected to the same E-Stop Safety
Module:
• The contacts of both switches must
be connected together in series. This
series combination is then wired to the
respective Safety Module input. Never
connect the contacts of multiple E-
stop switches in parallel to the E-Stop
Safety Module inputs; this defeats the
switch contact monitoring ability of the
Safety Module, and creates an unsafe
condition.
• Each switch must be individually
actuated (engaged), then re-armed
and the E-Stop Safety Module reset (if
Manual Reset mode is selected). This
allows the monitoring circuits to check
each switch and its wiring to detect
faults.
Failure to do so could result in
undetected faults and create an unsafe
condition which could result in serious
injury or death.
