2-3 ELECTRICAL INSTALLATION	2
All wiring must conform to local and national
codes.
For intrinsically safe applications, re-
fer to drawing 1400184, page 10-2 of
this Instruction Bulletin.

Disconnect and lock out power before connecting the unit to the power supply.

Install all protective equipment covers and safety ground leads after installa- tion. Failure to install covers and ground leads could result in serious injury or death.

To meet the Safety Requirements of IEC 1010 (EC requirement), and ensure safe operation of this equipment, con- nection to the main electrical power supply must be made through a circuit breaker (min 10 A) which will discon- nect all current-carrying conductors during a fault situation. This circuit breaker should also include a me- chanically operated isolating switch. If not, then another external means of disconnecting the supply from the equipment should be located close by. Circuit breakers or switches must comply with a recognized standard such as IEC 947.

a.General

The power supply and signal wiring should be shielded. Also, make sure the signal wiring is grounded at the Model 3081 Transmitter end only. Do not ground the signal loop at more than one point. Twisted
