Device Safety Considerations
Reading these Instructions
Before operating the device, read these instructions carefully and understand their safety
implications. In some situations, improperly using this device may result in damage or injury. Keep
this manual in a convenient location for future reference. Note that these instructions may not cover
all details or variations in equipment or cover every possible situation regarding installation,
operation, or maintenance. Should problems arise that are not covered sufficiently in the text,
immediately contact Customer Support for further information.
Protecting Operating Processes
A failure of this device – for whatever reason -- may leave an operating process without appropriate
protection and could result in possible damage to property or injury to persons. To protect against
this, you should review the need for additional backup equipment or provide alternate means of
protection (such as alarm devices, output limiting, fail-safe valves, relief valves, emergency shutoffs,
emergency switches, etc.). Contact Remote Automation Solutions for additional information.
Returning Equipment
If you need to return any equipment to Remote Automation Solutions, it is your responsibility to
ensure that the equipment has been cleaned to safe levels, as defined and/or determined by
applicable federal, state and/or local law regulations or codes. You also agree to indemnify Remote
Automation Solutions and hold Remote Automation Solutions harmless from any liability or damage
which Remote Automation Solutions may incur or suffer due to your failure to ensure device
cleanliness.
Grounding Equipment
Ground metal enclosures and exposed metal parts of electrical instruments in accordance with OSHA
rules and regulations as specified in
Design Safety Standards for Electrical Systems , 29 CFR, Part 1910,
Subpart S, dated: April 16, 1981 (OSHA rulings are in agreement with the National Electrical Code).
You must also ground mechanical or pneumatic instruments that include electrically operated
devices such as lights, switches, relays, alarms, or chart drives.
Protecting from Electrostatic Discharge (ESD)
This device contains sensitive electronic components which be damaged by exposure to an ESD
voltage. Depending on the magnitude and duration of the ESD, it can result in erratic operation or
complete failure of the equipment. Ensure that you correctly care for and handle ESD-sensitive
components.

Removing/Replacing Termination Boards
CAUTION
MAY CAUSE INJURY TO PERSONNEL OR DAMAGE EQUIPMENT
Because I/O, ground, and other wires enter the flow computer through conduit fittings
and then connect to the termination board, a qualified technician must disconnect all
wiring coming into the flow computer and pull it out through the conduit fittings in
order to replace the termination board.
You must then install the new termination board and completely rewire the unit.
If not already done, be sure to label all wires before disconnecting so you can identify
them later during the rewiring process.
The FB1100 Flow Computer includes a single type of termination board that uses 6-
connector pluggable terminal blocks.

The FB1200 Flow Computer supports the same termination board and blocks. In
addition, if the FB1200 Flow Computer is purchased with the 6-channel expansion I/O
board, it uses a different termination board with 8 (or in one case 9) connector
pluggable terminal blocks.
The basic methods for replacing termination boards or for replacing termination blocks
are the same, the only differences are the number of connectors on a terminal block
used on a termination board.
Restriction
Hazardous area approvals require that any part replaced in the field be the exact same
part (like for like). Upgrading or substituting different parts violates hazardous area
certification.

EXPLOSION HAZARD - - Substitution of any components may impair suitability for
Class I, Division 1 or Class I, Division 2.
WARNING!
EXPLOSION HAZARD - Do not disconnect equipment unless power has been removed
or the area is known to be non-hazardous.
WARNING!
EXPLOSION HAZARD - - Do not replace batteries unless power has been switched off
or the area is known to be non-hazardous. Batteries must only be changed in an area
known to be non-hazardous.
DANGER
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-
hazardous. Performing this operation in a hazardous area could result in an explosion.

14. You should be able to see through the housing from back to front and see the
opposite end of the captive fastening screws that you saw in Steps 11 and 12.
15. Take the new (replacement) termination board (399185-01-1 or 400216010-KIT),
and align it with the captive fastening screw holes and press it into the back of the
housing onto the captive fastening screws.
16. Tighten the screws that you loosened in Step 12. Torque screws to 6 in-lbs (0.7 N
m).
17. Take the battery pack enclosure/HMI module assembly you removed in Step 8.
Being careful to keep the battery wire and its connector free, carefully slide the
assembly into the front of the housing so that the HMI module mates with the
green and yellow connector from the CPU module. Tighten the screws to hold the
assembly in place. Torque screws to 6 in-lbs (0.7 N m). If battery-powered, re-
connect the battery.
18. You can now proceed to rewire all connections (I/O, communications, grounding)
to the flow computer. Please refer to the instruction manual for wiring installation
instructions.

Flow Computer 8-connector pluggable terminal block Field Installed Accessory
Kit Part No. 395803000-KIT for use with UL Listed Model Series FB1200.
If one or more terminal blocks becomes damaged, you may need to replace them.
•For 6-connector terminal blocks you need a 1/8 inch flat head screwdriver.
•For 8-connector (or 9-connector) terminal blocks you need a 3/32 inch flat head
screwdriver.
Tip
If you have more than one terminal block to replace, we recommend you replace
one terminal block at a time to avoid confusion.

4. Remove power at terminal block TB1.
5. If your unit doesn’t include an internal battery, skip to Step 8. If the unit has an
internal battery which is connected, use a #1 Phillips-head screwdriver to loosen
the four captive fastening screws on the HMI module.

7. If battery-powered, disconnect the internal battery.
8. For the terminal block you want to replace, make sure you note which wire goes to
which terminal. If they aren’t labeled, you should label them, or take a digital
photo so you know which wire goes to which connector of the terminal block.
9. Place your fingers on each of the short sides of the terminal block and gently rock it
back and forth so it pops out of the termination board.
10. Use a flat head screwdriver to loosen the screw for each wire coming into the old
terminal block. Slide the same wire into the identical position on the new
(replacement) terminal block, and tighten the screw to hold it in place. Repeat for
each wire.
11. Repeat Steps 8 through 10 for each terminal block you want to replace.

12. If you have an internal battery, you can re-connect it now, and put the HMI module
back on. To replace the HMI module, line up the printed circuit board (PCB) with
the slot on the back of the replacement module and gently press the new HMI
module on. Tighten the four captive fastening screws with a torque of 6 in-lbs (0.7
N m).
13. You can now plug your new terminal blocks back into the termination board,
leaving TB1 last for when you want to restore power.
14. Carefully align the end cap threads with the threads of the enclosure and replace
the rear end cap. Screw the end cap clockwise (eight full turns) until it is tightly
sealed to the enclosure. Endcaps must have at least 8 full threads engaged upon
reassembly.
Note
If you need more leverage place a long screwdriver or other appropriate tool
across the two notches in the cover to act as a pry bar.
15. If applicable, tighten the retaining clamp onto the end cap using a 3mm
hexagonal wrench. When tightening, torque to 10 to 12 in-lbs (1.1 to 1.4 N m).
