Important notes

{
Danger!
All power connections (L1, L2, L3, 1U, 1V, 1W, 2U, 2V, 2W, B1, B2 and BN) can
l
carry dangerous voltage when the starttec is connected to the mains. Therefore
the starttec must be disconnected before you start working on it or open the
housing.
After the connection of a PTC thermistor or thermostat (NC contact) all control
l
terminals only have a basic insulation (single isolating distance):
– Protection against contact - in the event of a defective isolating distance - can
only be ensured by external measures, e.g. double insulation.
Fuses and cable cross-sections
Cable cross-sections must be selected according to the max. input current.
l
Only use UL-approved cables, fuses and fuse holders for UL systems.
l
Observe national and regional regulations (e. g. VDE0113, EN 60204)!

1) ) Use UL-approved cables, fuses and fuse holders only. Use UL approved cables, fuses and fuse holders only.
UL fuse: 500 ... 600 V, tripping characteristic "H" or "K5"
All-current sensitive e.l.c.b.
2)
Residual current circuit breakers must only be installed between mains supply and starttec.
l
Residual current circuit breakers can be accidentally triggered by simultaneous connection of several
l
starttecs to the mains.
