HygroPro User’s Manual

1.4.2b Compliance Requirements

The

HygroPro

installation must comply with EN 60079-14 in Europe

and with the National Electrical Code (ANSI/NFPA 70) or part one of
the Canadian Electrical Code (C22.1), as applicable, in North
America. In other regions, additional local codes may also apply.

1.4.2c Electrical Connections

The

HygroPro

transmitter is certified intrinsically-safe for use in

zone 0. However, the external power must be provided by one of the
following methods:

•

an isolated, intrinsically-safe, 24 VDC power supply mounted in
the safe area

•

an isolated zener barrier mounted in the safe area and installed
between a standard 24 VDC power supply and the

HygroPro

Refer to

Figure 6

on the next page for a typical hazardous (classified)

area

HygroPro

wiring diagram. This installation uses an

MTL706

zener barrier

, in accordance with the second option listed above.

If using serial communications with a PC, an isolated RS232-RS485
converter mounted in the safe area between the computer and

HygroPro

must be used. The converter is typically powered by its

own standard 24 VDC power supply.

!WARNING!

Do NOT power an RS232-RS485 converter from the

same intrinsically-safe 24 VDC power supply used

to power the HygroPro.
