2.1 Pre-Installation Considerations
Choosing a Location for the
Silo
Track
TM
CLOUD
Gateway:
1) Environment:
This
Silo
Track
TM
CLOUD
Gateway product is suitable for non-hazardous classified locations only. It can be used
indoors or outdoors, and any possible protection from direct precipitation is advisable. Note the temperature limits in the specifications.
2) Placement:
The hardened communication network used to interconnect the
Silo
Patrol
®
SMU &
Radar
Right
™ sensors permits the
RS-485 network to be extended as far as 3,300ft (1000m) end-end. This permits placement of the particular product in the area best suited.
3) Connectivity:
Also the method to connect the
Silo
Track
TM
CLOUD
Gateway to the cloud/internet should be considered when selecting a
mounting location.
a) Ethernet:
If you plan to use the RJ45 port to connect to your existing Ethernet, the
Silo
Track
TM
CLOUD
Gateway will have to be within
acceptable wiring distance from the internet server. You will also have to open ports 3197 and 3199 on your firewall for the Gateway
to communicate with the Cloud. The “Destination” for the firewall rule can be ‘my.devicecloud.com’ if needed.
b) Cellular:
If you plan to use the cellular connection method, the
Silo
Track
TM
CLOUD
Gateway’s position is more flexible. However, cell
tower signal strength and the site proximity to a cell tower should be taken into consideration. Position the
Silo
Track
TM
CLOUD
Gateway
such that there is direct line of sight to the tower for regions with weak cell service, and avoid mounting inside metal buildings. Elevated
locations are recommended for weak signal strength situations.
2.2 Mechanical Installation
Silo
Track
TM
CLOUD
Gateway Mounting:
(See Figure 1)
1) Location:
Select a mounting location in accordance with the Pre-Installation Considerations.
2) Empty the Enclosure:
Open the enclosure door. Disconnect the two co-axial cables that connect the antenna to the router.
Remove the (4) screws retaining the back panel. Now lift out the back panel assembly and set aside.
3) Preparation:
Locate the (4) mounting brackets and screws that are provided with the
Silo
Track
TM
CLOUD
Gateway. Mount these
to the rear of the
Silo
Track
TM
CLOUD
Gateway’s enclosure using screws provided. The brackets can be positioned vertically or
horizontally to accommodate your mounting condition. You can use the enclosure as a template to mark the locations of the four
corner mounting points. (See Figure 1)
4) Cable Entries:
Before mounting to the wall, determine where the cable entries will be located. The most preferred location is
along the bottom of the enclosure to minimize the chance of any moisture from entering the enclosure. The next best position is
on the side, but very low. Make sure the door will open freely and not interfere with the cable fitting location. The optimum is
at least (2) entries, one for power mains, and one or more for the RS-485 data lines.
NOTE:
Conduit entry or cable gland fittings
should be rated NEMA 4X and or IP65 in order to maintain the NEMA 4X and IP65 rating of the enclosure.
5) Cable Entry Machining:
Machine cable entries into the enclosure’s exterior where desired. The recommended method is with
a hole-punch sized for the desired fitting. A hole-saw or drill bit can also be used.
6) Mounting:
Secure the enclosure to the wall with size #10 fasteners thru the slotted holes in the mounting brackets. (See Figure 1)
7) Re-install the Back Panel Assembly:
Install the back panel assembly into the enclosure, with the router in the upper most
position, and secure with (4) corner screws. Re-attach the antenna co-axial cables.
2.3 Electrical Installation
(See Figure 2 and Figure 3)
1)
Permanently Connected Equipment -
It is recommended that disconnect devices be included in the system installation.
In installations where multiple circuits are used (i.e. independent circuits for the
Silo
Patrol
®
SMU’s power input, relay connections,
and sound), individual disconnects are required. The disconnects shall be within close proximity of the equipment, accessible to
operators, and marked appropriately as the disconnect for the associated circuit. Ensure the disconnect ratings are appropriately
sized for the circuit protected. (See Specifications Section)
2) Field Terminations -
All of the in-field connections to the
Silo
Track
TM
CLOUD
Gateway are to be made to right side of the DIN rail
mounted terminal blocks. These are labeled well and easy to access; there is no reason to make connections to any other points
within the
Silo
Track
TM
CLOUD
Gateway. Connecting to any points other than the DIN rail mounted terminals or altering the factory
wiring may result in permanent damage and/or create a shock hazard.
3) Circuit Separation -
Two cable entry locations are recommended to aid in maintaining separation of “hazardous live” (typically
mains voltages such as 115VAC and 230VAC) and limited circuits (typically control voltages less than 30Vrms or 42.4VDC).
However, since the Gateway single wiring compartment cannot absolutely protect against physical contact between multiple
circuits, it is required that all wiring have an insulation rating of 300V minimum, and a temperature rating of 176°F (80°C) minimum.
4)
Protective Earthing -
The Gateway is provided with a “protective conductor terminal” earth ground potential. This terminal
shall be used to eliminate shock hazard in the unlikely event of internal insulation break down. Select wire size that can carry in
excess of the sum of all circuit’s maximum amperage.
5) Power Input -
The AC version of the
Silo
Track
TM
CLOUD
Gateway is designed to accept 100 to 240 VAC. Connect power as shown
to “L1” and “N” of the DIN rail mounted terminal blocks.
6) Communications Link -
The communications line from the
Silo
Track
TM
CLOUD
Gateway and the
Silo
Patrol
®
SMU or
Radar
Right
™
sensors is via a RS-485 network cable with +D, -D, and shield (0V) terminals, using Modbus RTU protocol. Basic Modbus
protocol requires all (3) connections to be utilized at all of the devices on the RS-485 network. The RS-485 network will be
connected to earth ground within the
Silo
Track
TM
CLOUD
Gateway, but will be isolated at the
Silo
Patrol
®
SMU or
Radar
Right
™ sensors.
