1. Rotate keyswitch (1) on terminal base unit (2) clockwise to position 2 as
required for this type of module.
Do not change the position of the keyswitch after wiring the
terminal base unit.
2. Make certain the flexbus connector (3) is pushed all the way to the left to
connect with the neighboring terminal base/adapter.
You cannot install the module unless the connector is fully extended.
3. Make sure the pins on the bottom of the module are straight so they will
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.
The module is seated when the latching mechanism (7) is locked into
the module.
6. Make certain that you only connect terminal base units to other intrinsi-
cally safe system modules or adapters to maintain the integrity of the
intrinsically-safe backplane.
ATTENTION
This equipment is considered Group 1, Class A industrial
equipment according to IEC/CISPR Publication 11. Without
appropriate precautions, there may be potential difficulties
ensuring electromagnetic compatibility in other environments
due to conducted as well as radiated disturbance.
This equipment is supplied as open-type equipment. It must be
mounted within an enclosure that is suitably designed for those
specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from
accessibility to live parts. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent sections of this
publication may contain additional information regarding
specific enclosure type ratings that are required to comply with
certain product safety certifications.
