Power and Signal Wiring Requirements 

Mounting Location 

When mounting, Human Machine Interfaces (HMI) and Purge systems must be 

positioned to avoid radiated and induced interference.  Do not mount the unit in 

close proximity to a device that generates strong radiofrequency interference or 

electromagnetic interference.  HMI and Purge systems must be also positioned to 

avoid exposure to excessive heat.  Do not mount the unit in close proximity to a 

steam line, heated vat or oven. 

 

Gland Plates 

Before modifications can be made, Gland Plates must be removed.  Please note that 

metal shavings are detrimental to electronic systems. 

 

Machining 

Only make enclosure penetrations in designated locations.  All metal shavings must 

be collected and removed. 

 

Wiring Requirements 

AC power inputs require dedicated circuits or feeds.  Power from lines or circuits 

shared by motors, drives, welders, arc furnaces, or inductive lighting is not 

acceptable.  Conduits for HMI and Purge power should be separated from other 

conduits to prevent radiated or induced interference.  Devices that produce spikes, 

surges, and brownouts are detrimental to computers, and can corrupt data and 

interfere with purging systems.  Do not use a transformer or other device to step 

down a three phase circuit to run a HMI or Purge System. 

Communication wires and signals should be run in separate conduits and routed 

away from power conduits.  Providing isolation to prevent emissions from other 

conduits is essential to data integrity.  Long runs of parallel signal lines can cause 

“cross-talk” and corrupt data making communications unreliable or impossible. 

DC power should be provided by a dedicated power source.  If multiple units must be 

powered from a single DC supply, the power cables must be run directly from the unit 

to the supply.  Chaining power from one unit to the next is unacceptable.  Units can 

interfere with each other by developing noise due to the resistance of the wires.  The 

filtering is provided by the source or power supply. 

 

Additional Wiring 

It is not permitted to run wiring through the unit that is nonessential to the unit.  The 

cabinet is not a junction box. 

 

Adding Additional Equipment 

Installing additional equipment in units approved for hazardous classed environments 

violates the approval of the unit.
