the charging process.
GMC-I Messtechnik GmbH 9
• Measurement may only be performed on voltage-free equipment and devices.
• Measurements may not be performed under moist ambient
conditions, where condensation has occurred, or in explosive
atmospheres.
• Do not disconnect the measurement cables until the device
under test has been fully discharged.
• Observe accident prevention regulation (Health and Safety Policy DGUV regulation 3), “Electrical Systems and Equipment”.
• Do not perform measurements alone: always have a second
person help if possible.
• Make sure that measurement cables are connected correctly.
• Do not touch the test probes at any point beyond the finger
guard.
The METRISO PRIME+ may not be used:
• If visible damage is apparent
• With damaged connector, measuring or test cables (test cables may not, under any circumstances, be mechanically damaged or kinked, because impaired insulation characteristics
may otherwise result)
• If these no longer function flawlessly
In such cases, the devices must be removed from service and
secured against any possible inadvertent use.
Send the instrument to our Repair and Replacement Parts service
department in such cases (see chapter 12 on page 54).
Opening of Equipment / Repair
Attention!
!

2.1 Checklist for High-Voltage Tests
Measurements may not be performed under moist ambient conditions, where condensation has occurred or in
explosive atmospheres.
Personnel Safety
➭ Turn the machine under test off and lock it in the off position.
➭ Perform insulation resistance measurement.
➭ Make sure that the system is grounded.
➭ Secure the danger zone with barriers, closing even narrow en-
trance ways.
➭ Set up warning signs such that they are plainly visible.
➭ Set up warning lamps such that they are plainly visible.
➭ Attach the emergency stop button in a plainly visible fashion.
➭ Warn personnel working in the area of possible danger.
➭ Always turn the test instrument off with the key switch and re-
move the key before leaving the work area.
10 GMC-I Messtechnik GmbH
Safety Precautions for the Machine Under Test (recommended)
➭
Review the circuit diagrams and make a note of all electrical circuits.
➭ Disconnect the neutral conductor from the mains.
➭ Short circuit each electrical circuit to itself.
➭ Disconnect control circuits with overvoltage arresters, if the ar-
resters would be triggered by utilized test voltage.
➭ Disconnect PELV circuits (no high-voltage testing is required
for these circuits).
➭ Test insulation at each circuit with 1000 V.
(If insulation resistance is OK at 1000 V, no failures should
occur during the high-voltage test.)
➭ Disconnect frequency converters.
➭ Caution in TN systems!
The protective conductor is connected to the neutral conductor in the junction box. High-voltage is thus applied between
the phase conductors and the neutral conductor.
The neutral conductor must be cut if necessary, because it is
not disconnected from the mains by means of fuses.
Setting Up the Test Instrument
High-Voltage Test
➭
Test all circuits (conductors) against the protective conductor (all
switches in the mains circuit must be turned on, and testing must be
performed upstream and downstream from all relays and contactors).
➭ Remove all shorting devices after testing has been completed.
Testing Without Short-Circuiting
➭ Separately test all conductors from all circuits against the pro-
tective conductor (the machine could be damaged in the case
of arc-over).
Functions Test
➭ The machine must be tested for correct functioning after the
high-voltage test, especially as regards safety functions.
