Avoid Electrocution - Daikin PE-ADDA200 Service And Installation Manual

2.2 Avoid electrocution

Only personnel qualified in accordance with IEC (International Electrotechnical Commission) recommendations
may be permitted access to electrical components. It is particularly recommended that all sources of
electricity to the unit be shut off before any work is begun. Shut off main power supply at the main circuit
breaker or isolator.
IMPORTANT: This equipment uses and emits electromagnetic signals. Tests have shown that the equipment
conforms to all applicable codes with respect to electromagnetic compatibility.
RISK OF ELECTROCUTION: Even when the main circuit breaker or isolator is switched off,
certain circuits may still be energised, since they may be connected to a separate power
source.
RISK OF BURNS: Electrical currents cause components to get hot either temporarily or
permanently. Handle power cable, electrical cables and conduits, terminal box covers and
motor frames with great care.
Always disconnect the VFD from the power source before performing any maintenance or adjustment. The VFD
shall be deemed off when at least one of the following conditions is met:

All fuses connected in series with the power supply have been removed

The main switch is disconnected at all poles

No power is supplied to the VFD
AND

The power supply to the solenoid valve circuit is disconnected
AND

The DC-Link capacitors are discharged
CAUTION - Risk of Electric Shock: Before opening the enclosure, wait at least 20 minutes after
disconnecting the power supply, as indicated on the label applied on the Inverter
enclosure. This to make sure that all live parts are discharged.
NOTE: residual voltage (< 60 V) may still be present across the DC-Link after 20 minutes.
The device without its cover can be accessed only 20 minutes after the power supply has been switched off. This
time allows the DC-Link capacitors to be discharged to a safe voltage level.
CAUTION - Risk of Electric Shock: in case of malfunctioning of the discharge device integrated into
the inverter, the DC-Link capacitors may remain charged even after 20 minutes since
disconnection. Never touch the inverter while removing the enclosure. Always check
the DC-Link capacitors are discharged at least below 60 V before initiating any operation
on the inverter!
