2.3 lectrical Installation
2.3.1 Power Connections
Caution: Do not connect ower to your device until you have com leted all
in ut and out ut connections. Failure to do so may result in injury!
Connect the main ower connections as shown in Figure 2.4.
Figure 2.4 Main Power Connections
Table 2.3 Fuse Requirements
FUS Connector Output Type For 115 Vac For 230 Vac DC
FUS 1 Power * N/A 100 mA(T) 100 mA(T) 100 mA(T)
FUS 2 Power * N/A N/A N/A 400 mA(T)
For the low voltage ower o tion, in order to maintain the same degree of
rotection as the standard high voltage in ut ower units (90 - 240 Vac),
always use a Safety Agency A roved DC or AC source with the same
Overvoltage Category and ollution degree as the standard AC unit (90 -
240 Vac).
The Safety Euro ean Standard EN61010-1 for measurement, control,
and laboratory equi ment requires that fuses must be s ecified based on
IEC127. This standard s ecifies for a Time-lag fuse, the letter code “T”.
The above recommended fuses are of the ty e 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 a roval listings. A 1.0 Am IEC fuse
is a roximately equivalent to a 1.4 Am UL/CSA fuse. It is advised to
consult the manufacturer’s data sheets for a cross-reference.

In 4-Wire connections the voltage dro across long excitation lead wires of strain
gauge bridge may cause measurement errors. The out ut of a strain gauge
bridge also de ends on the stability of excitation voltage. To correct for voltage
dro and changes in excitation voltage, 6-wire in ut configuration and ratio
measurement are used.
In order for the Ratiometric to work ro erly, the External Excitation should
not dro below 4.6 Vdc.

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

2.3.5 Wiring Outputs (continued)
This device may also have a rogrammable communication out ut. The RS-232
