3.5.4 Checking For Absence of Voltage
DANGER
Power supply
The assembly contains energy-storing components (CAP and capacitors on the FDB
assembly)!
After switching off at the main switch or disconnecting from the main supply, hazardous
voltages are still present at some points of the assembly interior for a period of approx. five
minutes.
► Before performing any service work or disconnecting press-fit connections, make sure
that you check for absence of voltage - as described further below! Maintenance or re-
placement may only be performed when the assembly is de-energized.
► All press-fit connections for the CAP assembly and PS1 are of touch-proof design but
when connections are plugged in or unplugged while there is still residual voltage
(CAP capacitors are still charged, display lamps on PS1 or CAP still shine), this could
cause damage or destruction of these or other connected components!
Protective measures and rules of conduct
Tools / requirements:
●
The certified electrician or person instructed and trained in electrical matters must be familiar
with the voltage tester and with the particular details of the system (defined contact points for
determining absence of voltage).
●
Use certified voltage testers and phase testers with a certain fixed measuring range.
The use of universal and multiple measuring devices for determining the absence of voltages
is not permitted.
Only use two-pin voltage testers (DUSPOL) e.g. FLUKE T150 or T5-1000.
●
Knowledge of the user guide and all safety instructions specified by the voltage tester manu-
facturer is a requirement.
●
Observe the area of use for the measuring device (nominal voltage, protection class, voltage
type, switch-on period, temperature range, measurement category CAT IV).
●
Check the external energy source of the measuring device.
●
Wear closely fitting and closed workwear.
●
Technicians working alone must be able to take any occurring risks into consideration and to
master them. In the event of any confusion, consult your specialist superior.
Preparation:
●
Use the voltage testers in accordance with their intended use. Inspect them for damage prior
to use. Damaged devices or cables may not be used and are to be reported immediately.
●
Before performing any measurements, test the voltage testers for functionality on a comparat-
ive voltage source or perform an integrated function test.
●
Ensure safe handling/safe workplace. Take sufficient space for movement and lighting into ac-
count.
●
Secure the area against proximity and hazard from persons.
●
Pay attention to any nearby exposed or active parts. Secure the measurement area, if neces-
sary.
