Connections - Important notes

Danger!
Even if the starttec is inhibited (X3/28 = LOW), the connections 1V, 2V, B1 and B2
l
carry dangerous voltage!
After the connection of a PTC thermistor or thermostat (NC contact) al contact all
l
control terminals only have a basic insulation (single isolating distance).
Protection against contact - in the event of a defective isolating distance - can only
l
be ensured by external measures, e.g. double insulation.
Stop!
Connect the mains cable in phase. If the mains phases are mixed up, the following
l
error message will appear: Er252 ( a) or Er253 ( e).
The startec control mode (C0014) must be adapted to the wiring. Otherwise, the
l
starttec can be damaged:
– Two motors, one direction of rotation: C0014 = 0 (Lenze setting)
– One motor, change of direction of rotation: C0014 = 1!
Fuses and cable cross-sections
Cable cross-sections and fuses (slow) must be selected according to the max. input current.
l
Use UL-approved cables, fuses and fuse holders only.
l
Observe national and regional regulations (e. g. VDE0113, EN 60204)!
l
When using e.l.c.bs:
Only use all current sensitive circuit breakers ≥ 30 mA.
l
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
l
several starttec to the mains.
