Safety Messages for Wiring
When installing and operating flame-proof electrical equipment,
the relevant national regulations for installation and operation
(e.g., EN60079-14, IEC Wiring Regulations and NEC/CEC)
must be observed.
• To avoid electrical shock hazards, do not connect wires when
power is applied. Failure to observe this warning may lead to
serious injury or death.
• To maintain the flame-proof integrity of the enclosure, DO NOT
damage the cover or threads while disassembling or reassembling
the unit.
• Painting and surface finishes, other than those applied by
Federal Signal Corporation, are not permitted
.
• Cable termination should be in accordance with specifications
applying to the application. Federal Signal recommends that all
cables and cores should be fully identified.
• Ensure that only the correct equipment-certified glands are
used and that the assembly is shrouded and correctly earthed.
Gland entries are M20-1.5 6H with an option for the M25 entry
on the end of the increased safety box models. See Table 4 on
page 29 for choosing correct cable entry devices for Equipment
in Potentially Explosive Atmospheres.
• Because of space limitations, ensure the cable cores within the
unit are not too slack.
• In all countries, the wiring must comply with all national and local
codes and standards.
• Ensure that all nuts, bolts, and fixings are secure.
