SAFETY NOTES
WARNING!
This unit is intended for use with low voltage dc supplies. Connection of mains (line) supply volt-
ages will not only damage the unit, but may also cause an electrical shock hazard to be present at
operator accessible surfaces.
WARNING!
The supply voltage connector has two 0V pins, commoned together by the circuit board back-
plane, and two 24V (nom) pins which are also shorted together internally. This allows easy ‘daisy-
chaining’ of multiple units. Two separate power supply units may not be connected as to do so
may result in damage to the unit, and/or a potential fi re or explosion hazard.
CAUTION
Local lightning protection must be fi tted if the dc power supply unit is located more than 30 me-
tres from the visual supervisor(s) it is supplying.
Note: in order to comply with the requirements of safety standard BS EN61010, the recorder shall
have one of the following as a disconnecting device, fi tted within easy reach of the operator, and
labelled as the disconnecting device.
a. A switch or circuit breaker which complies with the requirements of IEC947-1 and IEC947-3
b. A separable coupler which can be disconnected without the use of a tool
c. A separable plug, without a locking device, to mate with a socket outlet in the building.
1. If a hazard could arise from an operator’s reliance on a value displayed by the equipment, the dis-
play must give an unambiguous indication (e.g. a fl ashing alarm) whenever the value is over range or
under range.
2. Where conductive pollution (e.g. condensation, carbon dust) is likely, adequate air conditioning/fi l-
tering/sealing etc. must be installed in the equipment enclosure.
3 The equipment is designed for process monitoring and supervision in an indoor environment. If the
equipment is used in a manner not specifi ed by the manufacturer, the protection provided by the
equipment might be impaired.
4. The battery within the unit must not be short circuited. When exhausted, the battery must be dis-
posed of in accordance with local regulations for poly-carbonmonofl uoride/lithium cells.
5. When connecting a USB device, it must be plugged directly into the instrument. The use of exten-
sion USB leads may compromise the unit’s ESD compliance.
6. There are no specifi c insulation requirements for external circuitry.
7.
In order to comply with CE requirements, the Protective-conductor terminal must be connected to a
protective conductor.
SYMBOLS USED ON THE EQUIPMENT LABELLING
One or more of the symbols below may appear as a part of the unit’s labelling.
CAUTION
When accessing the battery, or setting DIP switches etc. the operator must be at the same electri-
cal potential as the casing of the instrument.
When fi tting USB devices, both the operator and the device must be at the same electrical poten-
tial as the casing of the instrument.
