Installing Wiring
Note: The wiring must be gas and oil-resistant, color-coded, or tagged for identification
purposes, and rated for 300 V or higher. Data wires for new installations must be a
twisted-pair (unshielded) with 10 to 12 twists per foot.
Operating Environment
Environment Range
Relative Humidity 05 to 95% (non-condensing)
Minimum outside ambient temperature -13 °F (-25 °C)
Maximum outside ambient temperature 131 °F (55 °C)
To ensure proper unit performance, operation under severe environmental conditions may
require special options such as card reader heaters and so on.
Wiring External to Dispenser
To install the wiring external to the dispenser, proceed as follows:
1 Pull the wiring through the stub up and sealing fitting.
Notes: 1) Ensure that enough extra wire length (minimum of 5
feet or 2 meters) is provided to
make the run to the stub up location at the bottom of the electronics cabinet.
2) Remember that you may be routing the conduit over
to come up at the stub up to the
electronics cabinet. Depending on which end of the unit the stub up is on, you may be
routing across the entire unit length.
2 For the side column conduit entry, install a short two-inch threaded nipple into the top of the
sealing fitting.
3 For the side column conduit entry, install a capped pulling elbow. The use of a Killark
®
Y-3
fitting is recommended.
4 The remaining conduit must be made up to match the installation layout for the unit at the site.
The following is the list of the most common procedures for conduit entry to the right when
facing Side 1:
• The length of the conduit must extend straight out from the cap
ped Y fitting or pulling
elbow.
• For the side column entry, the conduit must then be turned by 90°
, vertical under the air
gap plate knockout.
• Use the required air gap plate knockout. Do not knock out any knockout
plugs that will not
be used as an opening for conduit.
