Safety Messages for Wiring
When installing and operating explosion-proof electrical equipment,
the relevant national regulations for installation and operation (e.g.,
EN60079-14 and IEC Wiring Regulations) must be observed.
• To maintain the explosion-proof integrity of the enclosure,
DO NOT damage the dome or threads while disassembling or
reassembling 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 component certified glands are used
and that the assembly is shrouded and correctly earthed. Gland
entries are M20-1.5 6H. Supply wires to be rated 85 °C minimum.
