2. General instructions
The following points must be observed when using the voltage detector PHEG –
otherwise danger to life and limb!
Type PHEG... voltage detectors may only be used in electrical DC systems with nominal voltages
(see rating plate) for which they are designated.
Voltage detectors type PHEG1... may only be used in installations with earthed negative or positive
poles (observe the rating plate of the voltage detector).
Voltage detectors type PHEG2 may also be used in installations without earthed poles, if the
installation‘s voltage against earth at each point is smaller or equal to the nominal voltage the
upper nominal voltage (in case of nominal voltage ranges) of the voltage detector used.
PHEG... voltage detectors must be inspected before use to ensure that they are functioning
perfectly.
The voltage detector PHEG… may only be held by the handle and guided from a safe operating
location. The operator must maintain the necessary safety distance to live parts.
When placing the test electrodes of the voltage detector PHEG... , keep them as far away as
possible from other live or earthed parts of the installation.
Type PHEG... voltage detectors consist of several elements (see point 4 operation / assembly, Fig. 1).
The PHEG... voltage detector can be used in indoor and outdoor installations.
The devices can also be used in wet weather conditions (design based on IEC 61243-1). However,
they must not be permanently energised for more than 1 minute.
Parts which are damp or covered in condensation (e.g., as a result of extreme temperature
fluctuations) must be wiped dry and, if necessary, allowed to come to the ambient temperature
before implementation.
The position of the voltage detector does not affect its proper electrical function. The operating
position depends on the local conditions of the installation.
For safety reasons, defect parts of the voltage detector must be withdrawn from further use.
When using the voltage detector, the limit values –25 °C to + 55 °C for temperature and 20% to
96% for relative humidity must be observed.
The response of the voltage detector should be checked from time to time at operating voltage
(lowest voltage of the nominal voltage range).
The connecting lead of voltage detector type PHEG2... must me kept as far away as possible from
unearthed parts.
