8 Disconnecting the Inverter from Voltage Sources
1. Disconnect the miniature circuit-breaker from all three line conductors and secure against
reconnection.
2. If a multi-function relay is connected, disconnect its supply voltage and ensure that the device
cannot be reconnected.
3. If an integrated or external DC switch-disconnector is connected, switch it off.
4. Wait until the LEDs, display and, if applicable, fault indicator have gone out.
5. If a DC switch-disconnector is installed, pull the
handle out. For this purpose, use an Allen key
(AF 3).
DANGER!
Danger to life due to high voltages in the inverter
Death due to electric shock
The inverter operates at high voltages and must be disconnected prior to carrying out any
work on the device. In addition, if the DC connectors are pulled out without first switching
off the DC switch-disconnector, a dangerous electric arc can occur.
• Disconnect the inverter as described in this section.
CAUTION!
Risk of burns due to hot DC lid
During operation, the DC lid on the left-hand side of the connection area can become hot.
• Take care not to touch the DC lid when working in the connection area.
NOTICE!
Electrostatic discharge can damage the inverter
Internal components of the inverter can be irreparably damaged by electrostatic
discharge.
• Earth yourself before touching any components.
