Installing the Ruskin Electronic Controller
Install the Electronic Controller on an adjacent
structural wall, plenum, or ductwork that is isolated
from excessive system vibration. Do not mount the
Electronic Controller to the fan housing.
Mount the Electronic Controller in a protected area
of an air handling unit or place the Electronic Controller
with similar control panels within the structure.
Install and store the Electronic Controller indoors in a
non-condensing environment.
Mount the Electronic Controller within 50 feet (15.24 M)
of the router to prevent voltage drop or distortion
between the Electronic Controller and the sensors.
Shorter cable lengths are better.
Mount the Electronic Controller on a flat surface
using these steps:
(note: The electronic controller must be accessible
while the fan is running.)
1. Securely mount the Electronic Controller on a wall
near the sensors, in a position where the display
can be easily viewed and the wiring connections
are accessible. Use four field-supplied fasteners
to mount the enclosure in an appropriate location.
Use fasteners suitable for the wall material.
2. Remove the six screws that secure the cover of
the Electronic Controller to access set-up menu
buttons.
3. Remove the appropriate conduit plugs on the top
of the Electronic Controller for connection of the
field wires to the circuit board terminal blocks (see
Figure 9).
4. Wire the supply power and outputs. See Wiring.
IMporTAnT: Avoid running this device’s wiring in
the same conduit as AC power wiring or with wiring
used to suppy highly inductive loads such as motors,
contactors and relays.
Tests show that fluctuating, erratic and inaccurate
signal levels are possible when AC power wiring
is present in the same conduit as the signal lines.
Mount the Electronic Controller and all wiring away
from variable frequency drives (VFD’s) and broadcast
antennas.
IMporTAnT: Mount the Electronic Controller within
50 feet of the router. Avoid cable loops or coils.
Shorter cable lengths are better.
IMporTAnT: Always connect CAT5e cables from the
sensors to the router, then the router directly to the
Electronic Controller. Damage to the Controller will
result if sensors are plugged directly to the controller.
If replacement cables between the router and the
Electronic Controller are needed, they must meet the
following spec:
CAT5e cable specs, with simple pairing:
CAT5e solid plenum cable
4-pair shielded, twisted pair cable
Shielded connectors
24 AWG solid bare copper conductor
Meets or exceeds CAT5e spec
Teflon insulated, plenum jacket
CMP rated for use in any area used for air return,
drop ceiling, airducts, and in public buildings
Compliant with EIA/TIA standards by ETL
CSA listed
note: Standard Ethernet cables and crossover
cables cannot be used because they do not have
the correct simple pairing for connecting the
router and the Electronic Controller.
The shielded sensor cables are hard wired and can-
not be replaced. If the connector on the sensor cable
needs to be replaced use the following pin-outs.
