SAFETY MESSAGES FOR WIRING
: When installing and operating flameproof 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 flameproof 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 the specifications that apply to the application. Federal Signal
recommends that all cables and cores 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 6 H with an option for the M25 entry on the end of the increased safety box models.
See Table 3 on page 11 for choosing the correct cable entry devices for Equipment in Potentially Explosive
Atmospheres.
•
Because of space limitations, ensure that 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.
