Installation and user guide for PLATINUM® inverters 3800 TL, 3801 TL, 4300 TL, 4800 TL, 5300 TL, 6300 TL, 7200 TL
Installation
3.4.2 Connect the AC voltage
DANGEr
risk of death due to high AC voltage!
f
Switch off the mains voltage supply (AC side) before connecting the
inverter (safety device).
f
Make sure that the central isolation device can be accessed freely.
f
Only connect the inverter to TN or TT networks (see IEC 60364-1) with
230 V.
f
Observe max. fuse protection permitted on the AC voltage side, see
“Technical data” on page 48.
f
Make the AC voltage connection with a cable isolator switch.
PLATINUM GmbH recommends a type C cable isolator switch.
f
If an external residual current protective device is required, PLATINUM
GmbH recommends using a residual current protective device (rCD)
of type A.
CAUTION
Destruction of the inverter!
f
Never connect inverters between two phases.
f
Never mix up the phases with PE or N.
f
Distribute the inverters across the three phases in such a way that the
differences between the AC power levels on the different phases do
not exceed the maximum permitted unbalanced load of the network
operator.
Prepare the connection cable for the AC voltage
Dimensioning the wire cross section is the responsibility of the
electrician and depends on the cable length and installation situation.

1. Protect the AC voltage connection lines with appropriate fuses, see “Technical data”
on page 48.
2. Strip 18 mm of insulation from the AC voltage connection lines and add wire-end
sleeves.
