4 Q-Controller Installation
4.1
Type and Location
The Q-Controller is designed and certified for installation in a fixed location. The
location should be indoors and dry. Please observe the temperature and humidity
specifications above for ambient conditions. Observe the possibility of leaks or possible
water damage from cleaning done in the area.
4.2
Method
Four mounting screw locations are provided on the base of the enclosure. The unit should
be mounted to a wall or other fixture that remains in a fixed location.
4.3
Positioning
The mounting height and location should provide easy access to the wiring terminals and
front-panel. Backlighting is provided for the display in case of low lighting conditions.
4.4
Cabling
Approved cable conduit and conduit connectors should be used to ensure a safe and
reliable installation. Check the local wiring code for more information. Make sure all
conduit connectors are screwed in tight and that they are not coming in contact with any
bare conductor.
We recommend using BELDEN 9841 for communications. This wire has 120 ohm input
impendence, which will eliminate RS-485 communication problems.
QEL warrantees and support only covers installation with proper cable. If in doubt
please contact QEL support personnel.
4.5
Connectors
The terminal block TB1 to TB20 accept 12 AWG to 24 AWG wire, Use 16 AWG or 18
AWG wire for Power Supply in long wiring runs, which can be up to 1km (1,000 meters)
long.
Make sure to observe wiring to the correct terminal blocks. Removable terminal blocks
are provided. Make sure there is no confusion about which terminal block to wire to.
Note:
Incorrect wiring to any of the terminals of the Q-
Controller could cause permanent damage to the unit,
which is not covered by the warranty. Incorrect wiring
could also cause fire, electric shock, or bodily injury.
Please observe the polarity on all connections.
