9 Disconnecting the Inverter from Voltage Sources
Prior to performing any work on the inverter, disconnect it from all voltage sources
as described in this section. Always adhere strictly to the prescribed sequence.
Procedure:
1.
Disconnect the miniature circuit- breaker and secure against reconnection.
2.
Disconnect the DC switch and secure against reconnection.
3.
Use a current clamp meter to ensure that no current is present in the DC cables.
4.
Release and remove all DC connectors. Insert a flat-blade screwdriver or an
angled screwdriver (blade width: 3.5 mm) into one of the slide slots and pull the
DC connectors out downwards. Do not pull on the cable.
5.
Ensure that no voltage is present at the DC inputs of the inverter.
6.
Remove the AC connector from
the jack.
Use a suitable measuring device to
check that no voltage is present at the AC connector between L and N and L and
PE.
10 Technical Data
Destruction of the measuring device due to overvoltage
•
Only use measuring devices with a DC input voltage range of 580 V or
higher.
Damage to the inverter due to electrostatic discharge
•Touching electronic components can cause damage to or destroy the
inverter through electrostatic discharge.
• Ground yourself before touching any component.
