of cable lugs, core-end sleeves or by the type of terminal, but not by soldering
alone.
Cable Glands
The cable gland shall be selected to match the cable diameter. The use of
sealing tape, heat-shrink tube or other materials are not permitted to make the
cable fit to the cable gland.
If an Ex “d” gland clamping by the sealing ring (compression) is used with
braided or armored cable, it shall be the type where the braid or armor is
terminated in the gland and compression takes place on the inner cable sheath.
Flameproof cable glands, adapters or blanking elements, having parallel
threads may be fitted with a sealing washer between the entry device and the
flameproof enclosure provided that the applicable thread engagement is still
achieved after the washer has been fitted. Thread engagement shall be at least
five (5) full threads. Suitable grease may be used as long as it is non-setting,
non-metallic and non-combustible and any earthing between the device and
the flameproof enclosure is maintained. SpectraSensors recommends using
STL8 screw thread lubricant or equivalent on all screw thread and its taped
opening. Refer to the Hardware Installation and Maintenance Manual for the
lubricant application procedure.
Unused cable entries shall be sealed with a flameproof blanking element, which
shall be fitted directly to the hole (no threaded adapter shall be used), and shall
comply with thread engagement requirements detailed above and shall be
secured against loosening.
The creepage distances and clearances shall not be reduced by
the method in which the conductors are connected to the
terminals.
Certified compound barrier seal type glands and cables shall be
used where appropriate in compliance with local regulations.
For flameproof enclosures, adapters shall not be used together
with blanking elements.
Do not use this lubricant on exposed current-carrying parts.
