3. National Electrical Code requires a minimum frontal
clearance of 36” for the enclosure.
4. Use eight 1 ½” screws for mounting IMPE-4 or ISPE-4.
5. Use four 1 ½” screws for IMPE-2 or ISPE-2.
6. The enclosure door has a 1/2" lip that extends past the
enclosure sides, concealing the edge of the enclosure next
to the wall. When surface mounting the enclosure leave
sufficient space between multiple enclosures to allow the
doors to be installed and swing free from each other.
General Wiring
Enclosure conduit knockouts: Top and Bottom; 25 - 1/2"
knockouts (50 total) for wiring in the top and bottom. In the
bottom center of the enclosure, seven of the knockouts are
separated by a low voltage barrier and must only be used for
low voltage. This isolates all low voltage runs from high
voltage runs. A metal cage surrounds the Controller area of the
enclosure and is adjacent to the low voltage barrier. Left and
Right; 2 - 2” knockouts (4 total) for wiring high voltage
between enclosures through the left and right sides. Typically
these knockouts are only used in surface mount installations.
Breaker Feeds to Controllers:
Vantage recommends that the Main Controller’s power be
wired to a dedicated circuit breaker. When multiple enclosures
containing controllers are in close proximity to one another, it
is recommended to share the same breaker to all Main
Controllers; no more than nine controllers may be connected to
a 20amp breaker – allow up to 200W@120VAC per InFusion
Controller. Do not share the same breaker with controllers and
modules.
Vantage Station Bus Wire Specification
Vantage wire, part #VDA-0113 – 2C, 16AWG / 1.31mm2, twisted,
non-shielded, <30pF per foot. Separate a minimum of 12" /
30.5cm from other parallel communication and/or high voltage
runs.
Main Controller to Main Controller Wiring
When connecting multiple Main enclosures via the Main
Enclosure Terminal Board’s Controller Bus screw terminals,
Vantage recommends their own or an equivalent wire, (see
Vantage Station Bus Wire Specification above) be used in runs
between Main enclosures. This is a polarized connection with
two “+” and two “–” screw terminals for in and out wire runs.
The maximum wire length for all controllers connected
together on one bus should not exceed 2,000ft. using the
above wire specification.
NOTE: InFusion Systems may also use Ethernet connections
for Controller to Controller communication. Please see the
InFusion Controller instruction sheet for additional information.
Station Bus Wiring
WireLink stations connect to the Station Bus screw terminals
on the Main Enclosure Terminal Board. Use Vantage station bus
wire, (above). Maximum total station bus wire for each run =
2,000 feet with no station more than 1,000 feet from enclosure
(typically the second half of the station bus loops back to
enclosure with only one end connected). Station Bus should be
separated a minimum of 12" from other parallel communication
and/or high voltage runs.
Main & Secondary Enclosure to Secondary Enclosure Wiring
Connecting a Main enclosure to a Secondary enclosure or
Secondary enclosure A to Secondary enclosure B, requires
16/18-gauge 4-conductor twisted, non-shielded wire. Three of
the wires are always used to connect a Main enclosure to a
Secondary enclosure and chained secondary enclosures. This is
a polarized connection with “+”, “–” and “Gnd” screw terminals
for communication. The 4th wire is for Manual Override and is
optional. Each Secondary enclosure bus can support two
Secondary enclosures for a maximum of six Secondary
enclosures (see InFusion wiring below) per Main enclosure.
Maximum wiring distance from Main enclosure to Secondary
enclosure is 200ft including an A/B Secondary system (e.g.,
100ft from Main enclosure to Secondary enclosure A and an
additional 100ft from Secondary enclosure A to Secondary
enclosure B).
Main Terminal Board Terminator
If only one or two Main enclosures are used, the Controller Bus
Termination switch must be ON. This switch is located on the
Enclosure Terminal Board. If more than two Main enclosures
are used ONLY the first and last Enclosure Terminal Boards on
each controller bus should have the Network Termination
switch set to ON. Example: In a five Main enclosure system,
Main Controllers 1 and 5 may not be the first and last
Controllers. The daisy-chain “wiring” order could be 2-1-3-5-4.
In this example, Main enclosures 2 and 4 are the first and last
Controllers, so only these two would have the Network
Termination switch ON, the other three must be set to OFF.
RS-232 (Ports 1-5) for Main Enclosures
The Main Enclosure Terminal Board has five RS-232 ports. Use
these ports to connect any device that uses RS-232
communication. Only connect one RS-232 device at a time to
an RS-232 port. If additional RS-232 ports are needed, Vantage
also manufactures an RS-232 Station or, some products like
the IRX II, have built-in RS-232 ports.
Vantage typically uses RX, TX and GND for communication but
does have RTS and CTS for some applications on RS-232 Ports
1 and 2. RS-232 Ports 3-5 only have TX, RX and GND., however,
all five ports can use software flow control. The default
communication protocol may be changed through Design
Center software.
Communication protocol parameter settings:
Standard baud rates 1200 – 115.2K
7-8 Data Bits
Even, Odd, Forced or No Parity
200ft. maximum wiring distance
Default protocol for RS-232 communication is:
Baud: 19200
Parity: None
Total bits: 8
Stop bits: 1
RS-485 Connections
The Main Enclosure Terminal Board has two RS-485 ports.
These ports are connected to the same screw terminals used
for Secondary enclosure ports 3 and 4. The ports may not be
used for Secondary enclosure support and RS-485 support
simultaneously. However, if Secondary enclosure bus ports 3
and/or 4 are free they may be used as RS-485 communication
ports. The RS-485 ports are half-duplex, meaning that each
port can transmit and receive but not at the same time.
Maximum wiring distance for RS-485 ports is 200ft.
Possible Ground Loop Issues
All RS-232/RS-485 connections between third party
equipment and RS-232/RS-485 connections on the Main
Enclosure Terminal Board may produce a ground loop. Most
often, the connected RS-232/RS-485 device is not using the
same power source or is far away from the Vantage enclosure
resulting in a possible ground loop that may produce a data
noise condition. If this condition is suspected, Vantage
recommends a third party RS-232/RS-485 Opto (optical)
Isolation Module. Opto Isolation provides a communications
link and is an important consideration if a system uses different
power sources, has noisy signals or must operate at different
ground potentials.
Auxiliary Power
The enclosure, Main Enclosure Terminal Board has a 12VDC
auxiliary power connection. The 12VDC connection is typically
used for one RFE1000 RadioLink Enabler or one RFLC-V232
Enabler. Total power is limited to 250ma. NOTE: Do not
