This equipment is suitable for use in Class I, Division 2,
Groups A, B, C and D or Non-hazardous locations only
WARNING: EXPLOSION HAZARD –
Do not disconnect
equipment unless power has been switched off or the area is known to
be non-hazardous.

WARNING: To avoid the risk of electric shock or burns, always
connect the safety (or earth) ground before making any other
connections.
WARNING:
To reduce the risk of fire, electrical shock, or physical
injury it is strongly recommended to fuse the voltage measurement
inputs. Be sure to locate fuses as close to the source as possible.
WARNING
:Replace fuse with the same type and rating to provide
protection against risk of fire and shock hazards.
WARNING :In the event of repeated failure, do not replace the fuse
again as a repeated failure indicates a defective condition that will not
clear by replacing the fuse.
WARNING: EXPLOSION HAZARD – Substitution of
components may impair suitability for Class I, Division 2

Getting Started:
1. Connect the 24VDC power as shown on the connector
below.
2. Install i

Configurator onto your PC.
3. Connect serial programming cable into port MJ1 port.
4. If using a USB to serial convertor (PC501), please check
in Window Device Manager which com port has been
assigned. Then enter menu Tools->Editor Options->
Communications port->Configure, and set accordingly.
5. Press the up and down arrows simultaneously on
the front of the unit and check Network ID. Then press
the target sign in the Configurator and make the
Target ID match that of the i

Wiring Specifications
For I/O wiring (discrete), use the
following wire type or equivalent:
Belden 9918, 18 AWG (0.8 mm
2
) or
larger.
For shielded Analogue I/O wiring,
use the following wire type or
equivalent: Belden 8441, 18 AWG
(0.8 mm
