Safety First ..............Don't assume anything............. Always double check.
If in doubt, ask someone who is QUALIFIED to assist you in the subject.
Warnings
Please carefully read this manual and all warnings. Install the display
ONLYwhen you are sure that you’ve covered all aspects.
Check that the model number and supply voltage suit your application
before you install the display.
Connect the display according to current IEE regulations, IEC61010 &
NFPA:70 National Electric Code in USA.
We designed this meter for Pollution-Degree 2 environments.
It is sealed to IP65 NEMA4 all round for wall and suspension mounting
versions with glands on the bottom surface.
Power supplies to this equipment must have anti-surge (T) fuses at
2A for 230V supply, 5A for 110V supply or 5A for DC supplies in the
range 11-30VDC. Aswitch or circuit breaker, clearly marked as a
disconnecting device, must be included close to the installation.
Don’t touch any circuitry after you have connected the display, because
there may be lethal voltages on the circuit board.
Only adjust on-board switches or connections with the power turned off
Make sure all screw terminals are tight before you switch the meter on.
Only clean the display’s case with a soft damp cloth. Only lightly dampen
with water. Do not use any other solvents.

Rear case screws - please note
The rear panel is held in place with finger-screws, which
only need to be gently tightened.
Do not use tools to tighten or loosen the screws, as
this could cause damage to the internal threads.

General Description
The FUSION Series of displays accept industrial sensors to allow various
physical measurements to be made, such a weight, temperature, pressure,
humidity etc. Different models are available for different sensor types.
The main function of the FUSION series is to give a large numeric readout of
the variable being monitored. You can choose from various digit sizes and
formats. Most models include an excitation power output, to power the sensor
directly.
Optional output modules are also available, to give alarm relay outputs, analogue
output or digital communications, or any combination of these options.
Displays are programmed using front panel pushbuttons. The buttons may be
locked with a switch. The buttons may also be wired remotely, so that you can
make your settings from ground level.
These displays have two power supply options : 100-240 VAC or 11-30VDC
These units must be installed fully assembled, and must be installed according
to local electrical installation rules. When properly installed, with glands on the
lower surface, they provide ingress protection to IP65 / NMA4X
Safety
Obey all safety warnings in this manual, and install the display according to
local wiring and installation regulations. Failure to follow these guidelines may
cause damage to the display, connected equipment, or may be harmful to
personnel.
Any moving mechanical device controlled by this equipment must have suitable
access guards to prevent injury to personnel if the meter should fail.

Caution: There is a risk of electrical
shock if this instrument is not properly installed
Caution: Risk of danger: Read the whole
manual before you install this meter

Mounting and Installation
Install your Fusion display according to local electrical regulations.
Mount it away from moving machinery, to minimise the chance of damage, and
keep away from sources of heat, plastics solvents and electrical and magnetic
noise, such as welding equipment, arc lighting, inductive machines etc.
The screws on the back of the display are necessary for sealing - do not omit
any screws.
Do not overtighten screws - it is sufficient to finger-tighten them. In no
circumstance use an electric screwdriver to remove or fit screws, or you will
damage the case threads and sealing will be impaired.
Power cables and alarm relay cables should be routed seaparately to input
signal, logic signal, serial data and analogue output cabling, to minimise the
chances of electrical interference.
8
Only open the case when power has been removed.
This display uses internal detachable screw terminal connectors. Refer to the
wiring diagram on the following page for the correct positioning of each wire.
Each cable is fed through a compression gland for sealing. All glands must be
sealed, unused glands must be plugged.
The conductors you use must be suitable for the meter’s temperature, current
and voltage rating, which is broadly described as follows:-
Cable Temperature Rating
All cables must be rated for operation up to 90C continuous.
Cable gauge
The connectors on this instrument can accept conductors up to 1.5mm2c.s.a.
The minimum cross sectional area shall be 0.5mm2
Cable insulation voltage rating
Cables shall have an insulation voltage rating of at least 380V continuous.
Wire preparation:
We recommend multi-strand wire, because it withstands vibration better than
single strand cable. Pull the wire firmly after you make the connection to confirm
it is tight.
Use screened cable for all signal and control wiring and connect the screen to
earth at the destination end only. Route signal cabling away from power cabling
and relay switching cabling, to avoid electrical noise interference.
Use a single, circular cable through each gland, diameter 4.5 to 6.5mm
Wiring Advice
No bare wires exposed
Terminal screwdiver - 3mm blade
Strip back
5mm max.
