• Ensure that the cable gland seal is in a relaxed state by unscrewing the seal nut until there is no
compression on the seal.
• Pass selected cable through the gland to desired position, then tighten seal nut by hand until heavy
resistance is felt, then rotate one full turn with the appropriate wrench.
• Start connecting the wiring according to the following steps in Section 6.2.,
When Using Rigid Conduit (Housing with ½” NPT Entry Holes)
• A hazardous area approved Conduit Seal must be installed within 18” off each used conduit port.
• Any unused conduit ports must be plugged using hazardous area approved plugs.
Note : Use one of the two provided ground bolts ( see Figure 6). to ensure a proper and reliable grounding
(electrical bonding).
Note: The connection of cables and conduits to the Rack Monitor should be made in accordance with
requirements of the relevant type of protection. Cables and cable glands must be in accordance with the
type of protection. Unused openings must be closed with blanking elements suitable for the relevant type of
protection. The blanking elements must be certified for the type of protection and can be removed only with
the aid of tools. The product connections must guarantee the degree of protection. Instruction Manual of the
certified cable glands and blanking elements must be observed. Used cable glands and cable shall be
suitable for operation at of least 75°C.
Note: Do not drill any additional (conduit) hole in the rack monitor enclosure. This will violate the enclosure’s
approvals and voids the warranty.
Note: The apparatus shall not be installed in an environment subject to acetic acid vapors.
Note: If the equipment is likely to come into contact with aggressive substances*, then it is the responsibility of the
user to take suitable precautions** that prevent it from adversely affected, thus ensuring that the type of
protection is not compromised.
• * Aggressive substances:
o Acidic liquids or gases that may attack metals or solvents may affect polymeric materials.
• ** Suitable Precautions:
o Regular checks as part of routine inspections or establishing from the material’s datasheet that it is
resistance to specific chemicals.
