Safety Manual 3

External Circuit Breaker Requirements
After installing all necessary conduit runs, make sure any remaining conduit
hubs, if installed with the analyzer enclosure, are CSA and/or UL Certified and
rated Type 4X.
Cable Installation
To avoid potential damage, cable systems and accessories should be installed,
so far as is practicable, in positions that will prevent them from being exposed
to mechanical damage, to corrosion or chemical influences, to the effects of
heat and to UV radiation. If cables are subject to other conditions, e.g.,
vibrations or continuous flexing, they shall be designed to withstand that
condition without damage.
When cables are secured to equipment or cable trays, the bend radius on the
cable should be in compliance with the cable manufacturer’s data, or be at least
eight (8) times the cable diameter to prevent damage to the cable. The bend
radius of the cable should start at least 25 mm from the end of the cable gland.
The hazardous area end of each core in multi-core cables shall either be
connected to earth or be adequately insulated by means of terminations
suitable for the type of protection.
Terminations
Connections shall be made in a manner consistent with the type of terminal,
type of protection and not introduce undue stress on the connections.
If multi-stranded and, in particular, fine-stranded conductors are employed,
the ends shall be protected against separation of the strands, e.g., by means
Because the breaker in the customer-provided power distribution
panel or switch will be the primary means of disconnecting the
power from the analyzer, the power distribution panel should be
located in close proximity to the equipment and within easy reach
of the operator, or within 10 feet of the analyzer.
Thread lubricant must be applied on all conduit hub threaded
connections. SpectraSensors recommends using STL8 lubricant
on all conduit screw thread and it’s taped openings.
Insulation of multi-core cables by tape alone is not permitted.
