General information about electrical installation
■
High voltage warning
The voltage of the frequency converter
is dangerous whenever the equipment is
connected to mains. Incorrect installation of
the motor or frequency converter may cause damage
to the equipment, serious injury or death. Comply
with the instructions in this manual, as well as national
and local rules and safety regulations.
Touching the electrical parts may be fatal - even after
the equipment has been disconnected from mains:
Wait at least 4 minutes for current dissipate.
NB!:
It is the responsibility of the user or installer
to ensure correct earthing and protection in
accordance with national and local standards.
■
Extra protection
RCD relays, multiple protective earthing or earthing
can be used as extra protection, provided that local
safety regulations are complied with. In the case of
an earth fault, a DC content may develop in the faulty
current. Never use an RCD (ELCB relay), type A, as
it is not suitable for DC faulty currents. If RCD relays
are used, local regulations must be complied with.
If RCD relays are used, they must be:
-
Suitable for protecting equipment with a DC content
in the faulty current (3-phase bridge rectifier).
-
Suitable for a pulse-shaped, brief discharge
on power-up.
-
Suitable for a high leakage current.
N must be connected before L1 for single phase 200
V reduced leakage current units (type code R4).
■
High voltage test
A high voltage test can be performed by short-circuiting
terminals U, V, W, L1, L2 and L3, and applying
max. 2160 V DC in 1 sec. between this
short-circuit and terminal 95.
