8200w² Monitor Instruction Manual
(Refer to BS7671, section 522 “Selection and erection of wiring systems in relation to external
influences” for guidance).
Shrouded Bootlace Ferrules should always be used when terminating conductors.
4.4.2 DC Power Connections
The DC power connection is a 3 way terminal strip, located furthest right of the termination
bank. The left terminal is the Positive (+) supply, the Right terminal is the Negative (-) or Zero
voltage supply and the centre terminal is the Ground.
The power supply is galvanically isolated from all other terminals on the 8200w² Monitor. It is not
necessary to connect a ground to the monitor,.This terminal has been provided for convenience.
The DC powered 8200w² Monitor is powered typically from a 12V to 24V DC supply.
Min/Max Voltages are 9V to 36V. We do not advise operating the monitors in the field at
voltages approaching the Min or Max values as surges, dips or ripples in supply can fall outside
the Max/Min limits and can cause damage or interruptions to the performance of the 8200w² Monitor.
It is recommended that a circuit protective device (5A Trip) or fuse (5A anti-surge fuse) is fitted to the supply
voltage in close proximity to the monitor and located in a position where it is not difficult to operate, replace
or reset the device. The monitor has an on-board 3.5A fuse for internal protection and is fitted with a reverse
polarity diode.
In addition to the protective device, we advise a local isolator or disconnection switch is fitted in close
proximity to the monitor to allow easy disconnection or isolation of the monitor. This switch should be in easy
reach of the operator and clearly marked as the disconnection device for this equipment. This allows for easy
power-down of the monitor during servicing or periods where the monitor is not being used.
NOTE: If the equipment is used in a manner not specified by this manual, the protection provided by the
equipment may be impaired.
4.4.3 AC Power Connections
The AC power terminal strip is a 3 way connector, located furthest right of the termination bank.
The left terminal is the Earth (E), the Right terminal is the Live supply (L), and the centre
terminal is the Neutral Supply (N).
The AC powered 8200w² Monitor is powered typically from a 100VAC to 240VAC 50/60Hz
supply.
Min/Max voltages are 85VAC to 264VAC, 47Hz-63Hz. We do not advise operating the monitors
in the field at voltages approaching the Min or Max values as surges, dips or ripples in supply
can fall outside the Max/Min limits and can cause damage or interruptions to the performance
of the 8200w² Monitor.
The supply voltage should be fitted with a 3A Type C MCB (the monitor is prone to inrush currents during
initial power up, therefore a “Motor Rated” Type C MCB should be used to prevent nuisance tripping).
It is recommended that a circuit protective device or MCB is situated in close proximity to the monitor, and
located in a position where it is not difficult to operate or reset the device.
In addition to the protective device, we advise a local isolator or disconnection switch is fitted in close
proximity to the monitor to allow easy disconnection or isolation of the monitor. This switch should be in easy
reach of the operator and clearly marked as the disconnection device for this equipment. This allows for easy
power-down of the monitor during servicing or periods where the monitor is not being used.
The monitor should be adequately earthed. Circuit Protective Conductor (Earth conductor) Cross Sectional
Area (CSA) should not be less than the CSA of the calculated phase conductors.
(Refer to BS7671, section 543 “Protective Conductors” for guidance).
NOTE: If the equipment is used in a manner not specified by this manual, the protection provided by the
equipment may be impaired.
All external wiring should comply with local wiring regulations and standards.
The monitor has an insulation resistance of 3KV, however, care should be taken when conducting insulation
resistance tests. We advise the AC terminal strip is disengaged from the circuit board before such tests are
carried out.
