Conduits - Omntec OEL8000II Installation Manual

Overview
♦ Splice probe wires using the SK-4 connector sealing kit
♦ Probe cables and sensor cables must be completely enclosed in conduit from the
junction box to the console (contact factory for direct burial applications)
♦ Probe and sensor cables may share the same conduit
♦ Probe and sensor cables must be run in conduits that are separate from other
wiring.
♦ All wiring must enter the controller through the designated preformed knockouts
(see Appendix D – OEL8000II Controller).
WARNING
Note: Direct burial wring is available. Contact manufacturer.
1.5.2
Base the location and number of conduits required for the installation on the number
and diameter of the probe and sensor cables. Use a junction box inside the building to
combine the cables as described below. Observe the applicable codes pertaining to
which cables may or may not be combined into a single conduit.
You must have separate conduits as follows:
♦ 120 VAC Power cables must be combined in a separate (isolated) conduit.
♦ All Annunciator (RAS series) cables must be combined in a separate (isolated)
conduit.
♦ MTG Probe and Sensor cables may share a separate (isolated) conduit.
♦ RS-232, RS485, and Telephone cables may share a separate (isolated) conduit.
♦ Alarm relay cables must be combined in a separate (isolated) conduit
Use and select the proper conduit types and sizes in accordance with applicable
codes. Even in situations where they are not required by code, it is
recommended that they be used to protect wiring.
Note: Make certain that all conduits and junction boxes are dry and watertight. Wet
wires can result in the faulty operation of the system.
Observe the following when selecting and installing conduit:
♦ Determine the conduit size based on the number and size of cables it will carry.
♦ Plan the conduit installation so that the junction box in the manway will not
become submerged in water after a heavy rain.

Failure to comply can create an electric shock or
explosion hazard causing death, personal injury, or
property damage.
