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 maintain the flame-proof integrity of the enclosure, DO NOT damage the
LED lens cover or threads while disassembling or reassembling unit.
• 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.
• 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 3 on page 26 for choosing the 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.

Preparing to Wire the Ex d Flameproof Models

SHOCK HAZARD: 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.
CIRCUIT BOARD DAMAGE: The DC beacons are polarity sensitive, and
MAY BE DAMAGED by incorrect electrical hookup. When connecting the
DC beacon to the voltage supply lines, POLARITY MUST BE OBSERVED. In
addition, damage will result if the voltage rating of the particular model is
exceeded by more than 10 percent.
