Clarification:
1) Connection of the auxiliary power source is not
compulsory
because it is fed internally by
the direct bus. Connection proves necessary if we want to save the position and the state
through the encoder output (emulation) when for safety reasons, the mains power is turned
off.
2) If the auxiliary power source is used, it is
essential
for it to be connected to the same
phases (2 out of 3 for three-phase) as the mains power supply (see recommended
diagram- FELX 306198 for single phase and FELX 306199 for three-phase
.
)
,
to avoid
damage to the appliance.
If this is not possible, this auxiliary power source can possibly originate from another circuit, but it
must, imperatively, be isolated from the system using a transformer whose secondary will not be
earthed. The voltage of the transformer secondary must be identical to the mains voltage (230V
for mono appliances or three-phase 230V).
4.4.4 Terminal block B1: brake supply
This terminal block is also able to receive a 24V power source voltage for the brake fitted to the
motor. It is supplied to the B2 motor terminal.
The customer is responsible for supplying an isolated, regulated, and filtered 24VDC voltage.
Protection against overvoltage by 1 Joule varistor, this protection is effective from 30V.
A 4A UL fuse must be used (UL recommendation) for +24V
DC
voltage.
4.4.5 Earth connection to the chassis
Chassis earth:
The cable cross-section must usually be identical to that of the mains connection in order to
comply with standards in force.
4.4.6 Short-circuit capacity
(UL 508 C certification)
“Suitable For Use on a circuit capable of delivering not more than 5000 rms symmetrical amperes
230 volts maximum”
4.4.7 Fuse specifications
(UL 508 C certification )
The auxiliary input must be protectected by the fuses F2 type : ATDR2, 2A, 600V class cc
made by Ferraz SHAWMUT.
