Model CTF878 Startup Guide
2.1.5
Installing the Electronics Console
Because the relative physical locations of the transducers and the CTF878 electronics console are important, use the
guidelines which follow to plan the CTF878 system installation.
2.1.5.1
Locating the Electronics Console
The standard CTF878 electronics enclosure is a NEMA-4X weather-resistant, dust-tight, indoor/outdoor type.
Typically, the electronics console is mounted in a meter shed. When choosing a mounting site, make sure that the
location permits easy access to the console for programming, testing, and servicing.
Note:
For compliance with the European Union’s Low Voltage Directive (2006/95/EC), this unit requires an external
power disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such,
clearly visible, directly accessible, and located within 1.8 m (6 ft) of the CTF878.
2.1.5.2
Mounting the Electronics Console
The standard CTF878 electronics package is housed in a NEMA-4X weather-resistant enclosure. Refer to Figure 24 on
page 39 for the mounting dimensions of this enclosure.
WARNING!
Proper grounding of the CTF878 chassis is required to prevent the possibility of electric shock. Use one
of the mounting screws as an external ground connection
(see Figure 25 on page 40).
2.1.5.3
Wiring the Electronics Console
When making electrical connections to the CTF878 flowmeter, refer to Figure 25 on page 40 for a complete wiring
diagram of the unit.
Except for the power connector, all electrical connectors are stored in their terminal blocks during shipment and may
be removed from the enclosure for more convenient wiring. Feed the cables through the conduit holes on the bottom
of the enclosure, attach the wires to the appropriate connectors and plug the connectors back into their terminal
blocks.
Note:
For compliance with the European Union’s Low Voltage Directive (2006/95/EC), a transparent plastic shroud
protects the electrical connections. The shroud must remain in place, except while wiring the unit. Reinstall
the shroud after the wiring has been completed.
