MECHANICAL INSTALLATION

WARNING

Do not use a 2011A Mechanical Relay Output Module when the
installation environment contains chemicals which can degrade the
materials used to seal the relay in the module. The sealing materials are
as follows:

 Polybutylene Terephthalate, Polyplastics Co. Ltd., Compound No.

3270

 Polyphelene Suffide, Summitomo Chemical Co. Ltd., Compound No.

3601GL30

 Epoxy Resin, Summito Bakelite Co. Ltd., SUMIMAC ECR-9107K

Degradation of the relay seal voids the Approval/Certification of the
instrument for use in Class I, Division 2, Group A, B, C or D hazardous
(classified) locations.

The controller power supply has the capacity to handle the base instrument load of 1220 mA
plus any mix of built-in and modular I/O loads such that the total current consumption does
not exceed 5000 milliamps (5 amps). Add the current consumption for the base instrument,
built-in I/O, and each I/O module using the planning form in Appendix A, Verify that the total
does not exceed 5000 milliamps.

2.3.2 I/O Module and Memory Module Installation Procedure

Install the modules as follows:

1. Loosen the retaining screw(s) in the front panel, Figure 1-1, and pull the instrument out of

its housing.

! CAUTION: Support the instrument from the front and bottom whenever the

instrument is outside its housing. Do not allow the full weight of the circuit
boards to be suspended unsupported from the front panel as this may
overstress the brackets at that end.

2. Place the instrument on a flat surface with the front panel overhanging the edge of the

surface so that the circuit board is firmly supported. This positioning assures that the
instrument is not damaged by the force applied when inserting I/O modules.

3. Plug each I/O module into its required location on the carrier board and tighten the

retaining screw.

4. Use the memory module as described in IB-1800-OPR Operation/Setup Manual.

NOTE:

When installing the memory module it is important to orient it so that the
catalog number label is visible when the module is plugged into the
connector on the CPU board.
