To install the module on a 1797 terminal base, see the figure and complete the
following.
1. Rotate keyswitch (1) on terminal base unit (2) clockwise to position 3
(1797-IE8 and 1797-IE8NF) or position 8 (1797-IE8H) as required
for the particular type of module.
2. Make certain the flexbus connector (3) is pushed all the way to the left
to connect with the neighboring terminal base/adapter.
3. Make sure the pins on the bottom of the module are straight so they
align properly with the connector in the terminal base unit.
4. Position the module (4) with its alignment bar (5) aligned with the
groove (6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit,
noting that the module is seated when the latching mechanism (7) is
locked into the module.
6. Remove cap plug (8) and attach another intrinsically safe terminal base
unit to the right of this terminal base unit if required.
ATTENTION
Do not remove or replace a Terminal Base unit while power is applied.
Interruption of the backplane can result in unintentional operation or machine
motion.
IMPORTANT
Do not change the position of the keyswitch after wiring the terminal base
unit.
IMPORTANT You cannot install the module unless the connector is fully extended.
IMPORTANT
Make certain that you only connect terminal base units to other intrinsically
safe system modules or adapters to maintain the integrity of the intrinsically
safe backplane.
