WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors,
which can remain charged even when the frequency
converter is not powered. Failure to wait the specied
time after power has been removed before performing
service or repair work, could result in death or serious
injury.
1. Stop the Compressor.
2. Disconnect the AC mains, permanent magnet
type motors, and remote DC-link power
supplies, including battery back-ups, UPS, and
DC-link connections to other frequency
converters.
3. Wait for the capacitors to discharge fully before
performing any service or repair work. The
duration of waiting time is specied in Table 1.2.
Voltage [V] Cooling capacity [TR] Minimum waiting time
(minutes)
3x200 4–6.5 15
3x400 4–5 4
3x400 6.5 15
High voltage may be present even when the warning LED
indicator lights are o.
