3.4.1 Startup for systems using explosion-proof conduit
1. Assemble conduit to the Transmitter Electronics Enclosure. A conduit seal is required
within 18 inches (457 mm) of the enclosure.
2. Check to make certain that all power to field wiring is turned OFF.
3. Check the serial number tag on top of the Transmitter Electronics Enclosure. Remove
the end cap with the serial tag marked with _H1(nearest its conduit entry) to gain
access to the transmitter electronics.
4. Pull the wires into the enclosure.
5. Complete the field connection wiring according to the system wiring diagram (see
Appendix A).
6. Repeat Step 2 through Step 5 for the Transmitter Electronics Enclosure with the serial
tag marked with _H2.
7. Apply electrical power to the system to ensure the field connections are working
correctly. Replace the end caps and allow the system to run for the time specified by the
customer (usually one week) and an electrician has fully tested the connections. After
the Acceptance Test is witnessed and approved, seal the conduit.
8. Power down the system and apply the sealing compound to the conduit and allow to
set in accordance with manufacturer specifications.
9. If required, install the security latches and wire seals on the Transmitter Electronics
Enclosure end caps (see Section 3.6.8 and see Figure 3-9).
10. If required, install the wire seals through the socket head bolts on the Base Enclosure
(see Section 3.6.8).
11. Connect electrical power to the system.
12. Set or configure the meter using Daniel MeterLink. For additional installation
information refer to the system wiring diagram (see Appendix A), Daniel MeterLink
Quick Start Manual (P/N 3-9000-763). Use the Daniel MeterLink Field Setup Wizard to
complete the configuration. Also see, Section 4.1in this Manual.
