III. PRODUCT DESCRIPTION

FUNCTION

Junction Boxes (J-Box) are used with bolt-on sensors and direct support products to assemble all connections,

wires and ttings.

FEATURES

• Half or full bridge circuits available

• Adjustable watertight strain relief ttings are provided for the sensor cable with plugs provided for

unused cable entry holes

• Water seal design consists of knife-edge contact with a at gasket between the cover and box resulting

in high contact pressure to keep moisture out

• Cable and conduit entry holes are in the bottom of the junction box to protect against water seepage

IV. MECHANICAL INSTALLATION

WARNING: REMOVE POWER FROM THE UNIT BEFORE INSTALLING, REMOVING, OR MAKING ADJUSTMENTS.

CAUTION: DO NOT INSTALL JUNCITON BOXES WHEN RAINING; MOISTURE WILL CAUSE CORROSION AND SYSTEM ERRORS.

GUIDELINES

There are two aspects to successful use of Load Stands — properly functioning Load Stands and appropriate

vessel support characteristics. Review the following list of error sources, and make the recommended

corrections before you install Load Stands:

• If mounting on a pipe leg, use the center mounting holes.

• Each Junction Box can be wired to a maximum of two Microcell sets (four units total).

• Rosette arrays - the four Mircocells on a support let (two sets, each consisting of a vertical and a

horizontal.

• Vertical Mircocells - one Junction Box can be wired to Mircocells from two support legs if the legs are suciently close to each other to allow the cables to reach.

• Locat the Junction Box on the support leg web or on a brace. Vertically, locate Junciton Boxes at a

convenient height, approximately 4 ft (1.2 m) from the ground. The exact location is not critical, but

ensure there is sucient cable length and that a drip loop will be formed by the Microcell cables when

wired to the Junction Box.

• When mounting, be sure there is enough clearance to open the front door completely. Removal,

insertion, and wiring of the modular PCB is done through the front of the unit.

NOTES:

1. Mounting hardware is not supplied by Kistler-Morse; #8-32

socket head cap screws and at

washers are recommended.

TO MOUNT THE JUNCTION BOX

1. Hold the enclosure against the wall in the desired location and mark the positions of the mounting holes.

Place the enclosure in a safe location.

2. Drill the mounting holes in the wall.

3. Attach the enclosure to the wall using hardware that will secure it rmly in place.

For the adalet version of the Junction Box, place the Junction Box in line with the conduit.

V. ELECTRICAL INSTALLATION

WARNING: REMOVE POWER FROM THE UNIT BEFORE INSTALLING, REMOVING, OR MAKING

ADJUSTMENTS

CAUTION: ONLY USE SIKAFLEX 1A POLYURETHANE SEALANT OR DOW CORNING RTV 738 OR RTV739. OTHER SEALANTS MAY CONTAIN ACETIC ACID, WHICH IS HARMFUL TO SENSORS AND ELECTRONICS.

GENERAL SAFETY

When using electrical equipment, you should always follow basic safety precautions, including the following:

• The installation and wiring of this product must comply with all national, federal, state, municipal, and

local codes that apply.

• Properly ground the enclosure to an adequate earth ground.

•

Do not modify any factory wiring. Connections should only be made to the terminals described in this section.

• All connections to the unit must use conductors with an insulation rating of 300 V minimum, rated for 212º F (105º C), a minimum ammability rating of VW-1, and be of appropriate gauge for the voltage and current required (see specications).

• Do not allow moisture to enter the electronics enclosure. Conduit should slope downward from the unit

housing. Install drip loops and seal conduit with silicone rubber product.

DISCONNECT REQUIREMENTS FOR PERMANENTLY INSTALLED EQUIPMENT

A dedicated disconnecting device (circuit breaker) must be provided for the proper installation of the unit. If

independent circuits are used for power input and main relay outputs, individual disconnects are required.

Disconnects must meet the following requirements:

• Located in close proximity to the device

• Easily accessible to the operator

• Appropriately marked as the disconnect for the device and associated circuit

• Sized appropriately to the requirements of the protected circuit (See specications)

WIRING SENSORS TO THE JUNCTION BOX (HALF BRIDGE: KM MICROCELLS, LCELL, LD2, LD3, LD360)

1. Remove the Junction Box cover.

2. Place a plastic washer on a water-tight tting. Thread the sensor cable through a cap and water-tight tting. Leave an adequate length of cable between the sensor and tting to provide a drip loop.

3. In the bottom of the Junction Box, locate one of the small holes closest to the terminal being used for

the sensor. Screw the water-tight tting into the hole.

NOTE: TB3 terminal block has 12 terminals to accomodate up to four sensors (A, B, C and D). Locate the

terminal labeled for the sensor that is being wired.

4. Estimate the required length of cable to the terminal strip; allowing a little extra for strain relief. Cut the excess cable.

97-1076-01 Rev. B

Page 10

www.kistlermorse.com

5. Strip back approximately 3 in. (76 mm) of the cable sheathing to expose the three wires inside. Strip back 1/4 in. (6 mm) of insulation from the end of each of the wires.

6. Connect the wires from the sensor to the selected TB3 terminals; black wire to B terminal, white wire to W terminal, and red wire to R terminal.

7. Perform Steps 2 through 6 for each sensor that needs to be wired to this particular Junction Box (up to four)

8. Spread of generous bead of sealant (Sikaex 1A polyurethane or Dow Corning RTV 738 or RTV 739) around the water-tight tting and the sides of the plug for each hole not being used. Screw a plug into

each hole.

9. Replace the Junction Box cover and screws if not ready to begin wiring them to ensure that no moisture enters the Junction Box enclosure.

WIRING JUNCTION BOXES TOGETHER AND TO CONTROLLER (HALF BRIDGE)

GUIDELINES

• One large hole for conduited installation: The large hole, which accommodates a 3/4 in. conduit tting, is for

wiring the Junction Box to the other Junction Boxes and to the controller.

• Two large holes for non-conduited installation: The two large holes, which accomodates PG13.5 cable ttings, are for wiring the Junction Box to the other Junction Boxes and to the controller.

• The following procedure assumes the conduit/cable trays have been installed.

• Seal all conduit ttings against water entry. Install drain holes at the conduit’s lowest elevation(s) to allow

condensation to drain.

• Use Belden 3-conductor shielded interconnect cable or equivalent to wire Junction Boxes together and to the controller. For lengths up to 1,000 ft ( 305 m), use 18-gauge Belden 8791 cable. For lengths from 1,000 to 2,000 ft (305 to 610 m), use 16-gauge Belden 8616 cable.

• When wiring cable to Junction Box terminals, strip back 3 inches (76 mm) of cable sheathing to expose the 3-conductor wires and shield wire inside. Strip 1/4 inch (6 mm) of insulation from the end of each of the conductor wires.

97-1076-01 Rev. B

1. Remove the Junction Box cover.

2. Route the 3-conductor cable through the tting into the junction box farthest from the controller.

3. Connect the wires from the cable to the TB3 terminal in the Junction Box.

Black wire to B Terminal

White wire to W Terminal

Red wire to R Terminal

4. Connect the cable shield wire to the Shield Terminal between TB1 and TB2.

NOTE: The shield terminal will not connect to anything; be sure to connect on the device side though.

5. Route the cable through the conduit/cable tray to the next Junction Box.

6. Estimate the required length of cable to the terminal strip, allowing for a little extra for strain relief. Cut the excess cable.

7. Connect wires from the cable tothe TB1 Terminal in the Junction Box - see Step 3 above.

8. Route another 3-conductor cable through the tting into this Junction Box and attach wires to the TB2

Terminal - see Step 3 above.

9. Repeat until all vessels are wired together.

10. Route the cable from the last Junction Box through the conduit/cable tray to the controller. Refer to the controller manual for wiring diagarams required to wire the Junction Box to the controller. One vessel takes up one channel in the controller; the channel shows the average value from all the sensors on the vessel supports.
