For the connection of the load current with
insulated
crimping cable lugs with 8mm rings, terminal studs are
envisaged that must be tightened with a torque of 5.5 - 6Nm. The cable lugs must be exactly vertical to the
conducting plate. When laying leads, you should ensure that the connection leads are not heated up directly by
the exhaust from the heat sinks. As load fuses, fuse units for the protection of semiconductors must be used.
Project planning of their size must be made according to the connected capacitive load. You must ensure that the
equipment grounding conductor is connected correctly. The equipment grounding conductor connection in the
form of an M6 hexagon bolt is located on the heat sink beneath the connections for the capacitor and is labeled
with the PE conductor sign
.
For reactor-protected equipment it is absolutely essential that the
THYRO
SWITCH
is connected in series
before inductor and capacitor.
Terminal 1(+) and 3(-):
For gating with 10-30V DC, terminal 1 must be connected to plus and
terminal 3 to minus.
(see design: DC gating on page 5)
Terminal 2 and 3:
For gating with 180-260V AC 50/60Hz, terminals 2 and 3 must be used.
(see design: AC gating on page 5)
Terminal 4 and 5:
The supply voltage 200-250V AC or 100-130V AC with 50 or 60Hz is connected
to terminals 4 and 5.
(see design: DC gating and AC gating on page 5)

Commissioning
1. Check the correct connections of the
THYRO
SWITCH
2. Attach plastic housing
3. Switch on supply voltage ("Power" LED lights up)
4. Possible test of gating by the controller ("Control" LED lights up and fan starts up)
Note:
The operational current may only be released for the initial commissioning if
no gating takes place, that is, the
THYRO
SWITCH
is switched off.
6. Connecting operational current
7. Release controller (for gating and correct function, "Power", "Control", "Thyr1" and "Thyr2" light up)
