2.3 Electrical Installation

2.3.1 Power Connections

Caution: Do not connect power to your device until you have completed all

input and output connections. Failure to do so may result in injury!

Connect the main power connections as shown in Figure 2.4.

Figure 2.4 Main Power Connections

Table 2.3 Power Connections

FUSE Connector For 115Vac For 230Vac DC

FUSE 1 Power * 100 mA(T) 100 mA(T) 100 mA(T)
FUSE 2 Power * N/A N/A 400 mA(T)

For the low voltage power option, in order to maintain the same degree of
protection as the standard high voltage input power units (90 - 240 Vac),
always use a Safety Agency Approved DC or AC source with the same
Overvoltage Category and pollution degree as the standard AC unit (90 ­240 Vac).

The Safety European Standard EN61010-1 for measurement, control,
and laboratory equipment requires that fuses must be specified based on
IEC127. This standard specifies for a Time-lag fuse, the letter code “T”.
The above recommended fuses are of the type IEC127-2-sheet III. Be
aware that there are significant differences between the requirements
listed in the UL 248-14/CSA 248.14 and the IEC 127 fuse standards. As a
result, no single fuse can carry all approval listings. A 1.0 Amp IEC fuse
is approximately equivalent to a 1.4 Amp UL/CSA fuse. It is advised to
consult the manufacturer’s data sheets for a cross-reference.

2.3.3 Two/Three/Four-Wire RTD

The figures below show the input connections and input connector jumpers
(shown in bold lines) required to hookup a 2-, 3- or 4-wire RTD.

Figure 2.6 a) RTD-1000 ohm and b) RTD-100 ohm Wiring Hookup

500 ohm Wiring Hookup

The two-wire connection is simplest method, but does not compensate for
lead-wire temperature change and often requires calibration to cancel lead-wire
resistance offset.

The three-wire connection works best with RTD leads closely equal in resistance.
The device measures the RTD, plus upper and lower lead drop voltage and the
subtracts twice the measured drop in the lower supply current lead producing
excellent lead-resistance cancellation for balanced measurements.

The four-wire RTD hookup is applicable to unbalanced lead resistance and
enables the device to measure and subtract the lead voltage, which produces the
best lead-resistance cancellation.

When configuring your monitor, select RTD type and RTD value in the Input
Type menu (see Part 3).

If the input wires of the meter get disconnected or broken, it will display

+OPN

“Input (+) Open” message except in case of 500/1000 Ω 2-wire

RTD. In this case the display shows

-OPN

“Input (-) Open” message. For
safety purpose you may want to set up your alarm to be triggered when
input is open. See Alarm 1 & 2 chapters for details.
