SAFETY INFORMATION
THIS SECTION FOR USE BY COMPETENT PERSONNEL ONLY
•WARNING READ SAFETY INFORMATION BELOW BEFORE
INSTALLATION
•WARNING Hazardous voltages may be present on the terminals -the
equipment must be installed by suitably qualified personnel
and mounted on an enclosure providing protection to atleast
IP20.
•ISOLATION The power supply terminals and associated internal circuitry
are isolated from all other parts of the equipment in
accordance with BS EN61010-1 for connection to aCategory
II supply (pollution degree 2)
Functional isolation (500v max) is provided between input
and output circuits, and between inputs and communications
(where fitted).
Any terminals or wiring connected to the input, output or
communications terminals which are accessible in normal
operation must ONLY be connected to signals complying
with the requirements for Safety extra low voltage (SELV)
circuits.
•WARNING If not installed in accordance with these instructions,
protection against hazards may be impaired
•Installation overvoltage category -2(as per BS EN61010-1)
•(If this equipment is to be used in environments with overvoltage category 3,
transient suppressors should be installed on wiring greater that 50VAC or
75VDC).
•The Mains supply to the equipment must be protected by a1Amp fuse and a
suitable switch or circuit breaker which should be near the equipment.
•The equipment contains no user serviceable parts.

MECHANICAL INSTALLATION
When installing the instrument into the panel, the following dimensions should be
taken into account.
The unit is held in the Panel by two metal clamp bars, on diagonally opposite corners,
fitted from the rear. Agasket is available, and should be fitted wherever sealing of the
instrument is required. See diagram below.
The maximum panel thickness is 3.5mm with agasket and 4.5mm without. The gasket
has aself adhesive side which should be stuck to the panel around the cutout. The
instrument may then be inserted and tightened against the gasket to form aseal. The
panel should be clean and smooth for the seal to be effective.

POWER SUPPLY
3.0 WIRING
This section describes how the instrument should be wired for the Power Supply,
Input Sensor or any Output options that may be fitted. All connections are made to
three or five way sockets which are removable for ease of wiring.
Installation should be undertaken in accordance with relevant sections of
BS6739 -British Standards code of practice for "Instrumentation in Process
Control Systems: Installation design and practice".
See important safety information on page 8
3.1 POWER SUPPLY
The Power supply rating will be
indicated on the top of the instrument.
Ensure that this is correct for the
voltage that is to be connected. If
there is adifference, refer to Service
Manual for details of power supply
adjustment.
Note that the power supply socket has
had polarisation keys fitted to prevent
insertion into any other plug at the rear
of the instrument.
The connection is made as shown.
Ensure that no bare wire protrudes from
the rear of the power connector risking
ashort circuit.
