  ciently tight.

The connections of the inputs and outputs, depending on the models, 
may be made: 

using traditional screw terminals;
using plug-in terminals with screw cable connection blocks;
using plug-in terminals with crimped cable connection blocks.
using plug-in terminals, which signifi cantly simplify the connection 
of the instrument both during installation and maintenance. This also 
avoids connection errors, as there are three connection blocks with a 
diff erent number of pins.

Connect the inputs and the outputs following the diagram shown on the 
instrument label.

For the 12 Vac versions:

if the power supply available is mains, a safety transformer is required 
to ensure double insulation between the power supply and the very 
low voltage electronics. If required, a fuse must be installed in series 
with the primary (32 mAT for code TRA12VDE00). The transformer-
instrument connection must be as short as possible;
if the power supply available is already low voltage, but not 12 Vac, 
a suitable adapting transformer must be used: double insulation 
between the primary and secondary and defi nition for surge on the 
primary to the appropriate level (2000 V for applications in industrial 
environments.

The voltage supplied to these terminals (see the wiring diagrams)  must 
correspond, within the specifi ed tolerances, to the value shown on 
the instrument connection label. The insulation of the instrument, for 
versions with mains power supply (230 Vac and 115 Vac), is reinforced. 
The versions with 12 Vac/Vdc power supply, on the other hand, do not 
feature such insulation.

2.3  Wiring diagram for multiple units 

Warnings:

the RS485 converter (IROPZ485S0)  is sensitive to electrostatic 
discharges, and therefore must be handled with extreme care;
check the technical documents on the CAREL IROPZ485S0 option for 
the description of the connection methods so as to avoid damaging 
the instrument;
suitably fasten the converter so as to avoid disconnections;
perform the wiring with the power supply disconnected;
keep the IROPZ485S0 serial option cables separate from the original 
wires (relay outputs and power supply).

The RS485 converter (IROPZ485S0) is used to connect the easy and easy 
compact instruments to the supervisor network, allowing complete 
control and monitoring of the easy units connected.
The system allows up to 207 units to be connected together, with a 
maximum length of 1000 m. For the connection, the standard accessories 
are required (RS485-USB converter CAREL code CVSTDUMOR0) and two 
120 Ω, terminal resistors, to be fi tted on the terminal block on the fi rst and 
last instrument connected.
Connect the RS485 converter to the easy or easy compact unit using 
a 4-wire cable and make the connections as shown in the fi gure. The 
line should be started and ended with a 120 Ω 1/4 W resistor. For the 
allocation of the serial address see parameter H0. The recommended 
connection cable is a twisted pair with shield and cross-section from 0.5 
to 1.5 mm

 (AW6 22-24).
