9. Inspection
This section is advisory only and does not presume full compliance with local regulation and/or
standards.
This section describes the requirements for the three phases of the equipment life.
The requirements are based on AS2381.7 - "Electrical equipment for explosive atmospheres -
Selection, installation and maintenance. Part 7: Intrinsic safety." This manual assumes that the initial
selection phase has already been completed and installation is about to commence. These
requirements are only applicable to Hazardous Area installations.
It is the responsibility of the supervisor to comply with all local relevant regulations and/or standards.
9.1. Pre-installation
The following information should be made available to the person(s) responsible for the installation,
prior to the time of installation, and should remain available to those responsible for the safe operation
of the installation:
9.1.1. The zone classification of areas in which each item of electrical equipment and any
interconnecting cables are to be installed.
9.1.2. The certificate number of the system.
9.1.3. A list of all uncertified items used in the installation. With the RCI-4100 IS system, for
example, uncertified items are loadcells, simple switches, junction boxes and potentiometer
type sensors. All these items are classified by the standard as simple apparatus and do not
require certification.
9.1.4. Details of the cable types used and their electrical parameters. For the RCI-4100 IS system,
there are two cable types specified, these being SWA for the Power and Motion control
signals (relays) and instrumentation cable for all other applications. When the cable is
supplied as part of the system, use the appropriate cable parameters supplied in the
Electrical Parameters section. When the cable is not supplied as part of the system, but is
obtained from a third party by the installer/customer/contractor/etc., it is the installer's
responsibility to determine the cable parameters. In either case, the parameters listed in the
certification documentation must be complied with. Maximum allowable cable length must be
checked against the requirements of each installation. In the application where the Control
Unit is located in a safe area, the SWA cable may be replaced with an unarmored
equivalent.
9.1.5. Refer to any special requirements listed in the certification documentation and note how
these requirements will be met in this particular installation. There are only three such
requirements for the RCI-4100 IS, these being:
• Installation must be as per the General Arrangement drawings and the cable parameters
must not exceed values specified in the relevant certifications. If the cables have been
supplied by LSI-Robway, then this condition will have been verified by LSI-Robway.
Should the cable be supplied from a source other than LSI-Robway, it is the installer's
responsibility to ensure that the cable meets the specified requirements.
• The Display Unit can only be installed in a Gas Group IIB, or safe area, must have a cable
length of not more than 10m connecting it to the Control Unit, and must have a cable type
with part number 90320R. It is a condition of certification that ONLY this cable type be
used between the Control Unit and the Display Unit.
