machine perimeter. Guards must be used only to limit personnel
access to hazards within the machine.
11. The human possibility of avoidance or limiting harm (e.g. reflex,
agility, possibility of escape) for all hazards associated with this
machine can be impossible. (EN 1050 7.2.3.3)
12. Hazards in this machine are to a person or several persons and
where the highest consequence may be serious (non-reversible)
injury or death. (EN 1050 7.2.2)
13. The E-Stop switches, interlocks with and without guard-locking
and any external power disconnect contactors must meet the
required standards :
EN 418 E-Stop equipment, functional
aspects
EN 60947-5-1 E-Stop and interlock switch contact
block requirements
EN 60947-5-5 E-Stop actuator requirements
EN 1088 Interlocking devices for guards
EN 60947-4-1 Electromechanical contactors
14. The E-Stop switch (or switches) must be placed where they are
readily accessible by machine operators as per EN 292-2 Section
3.6.
15. Power to devices from circuits connected to J
A
and J
B
and pins 6
& 9 on J5 must be protected from being touched by personnel,
i.e. these circuits are not accessible (as per EN 61010-1) within
the machine. These devices must require that a tool is used to
access any hazardous circuits or hazardous mechanical elements.
The cables which supply power to devices within the machine
from J
A
and J
B
and pins 6 & 9 on J5 should be clearly marked
with the shock hazard international symbol. There should be
marking on cables and components powered from this power
source, which states that the circuit is live and not interrupted by
safety interlock. An example of acceptable marking is shown
below.
Example label
16. Hazards that might exist in a machine, but that are not rendered
safe when electrical power is removed may include, but are not
limited to: chemical hazards, nuclear radiation, potential energy
(from springs, elevated loads, pressurized fluids and/or
pressurized gases), explosive materials, sharp edges, impalement
hazards, etc. are beyond the scope of this document. These
hazards can likely be controlled and monitored by a safety
control system based upon the eF-785, however, no attempt has
been made to consider them herein.
17. The machine must pass (or be able to pass) EN61010-1.
18. All accessible metal parts must be bonded to protective earth.
