2-3 ELECTRICAL INSTALLATION
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 5081
Transmitter end only. Do not ground the
signal loop at more than one point. Twisted
