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 the figure below.
Figure 2.3 Main Power Connections
Table 2.3 Fuse Requirement (see specifications)
FUSE Connector Output Type For 115Vac For 230Vac DC
FUSE 1 Power N/A 100 mA(T) 63 mA(T) 63 mA(T)
FUSE 2 Power N/A 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 2.5 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 controller, 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 and 2 chapters for details.

This device has snubber circuits designed to protect the contacts of the
mechanical relays when it switches to inductive loads (i.e. solenoids, relays).
These snubbers are internally connected between the Common (C) and
Normally Open (NO) relay contacts of Output 1 and Output 2.
If you have an inductive load connected between Common (C) and
Normally Closed (NC) contacts of the mechanical relays and you want to
protect them from the rush current during the switching period, you have
to connect an external snubber circuit between Common (C) and
Normally Closed (NC) contacts as indicated in the figure below.
