Prior to Installation
Check that Motor Full Load Ampere (FLA) is lower
than or equal to the starter Full Load Current (FLC)
and that the Main and Control voltages are as
indicated on the front panel.
Mounting
• The starter must be mounted vertically.
• Do not mount the starter near heat sources.
• Protect the starter from dust and corrosive
atmospheres.
Temperature Range and Relative humidity
The starter is rated to operate within the temperature
range of -10ºC (14ºF) to + 50ºC (122ºF).
Relative humidity inside the enclosure should not
exceed 95% non-condensed.
Do not interchange line and load connections.
Short Circuit Protection
For short circuit protection use M.V. fuses.
Transient Protection
When high transients are expected, external protection
should be used (consult factory).
WARNING
Power factor correction capacitors, if required must
be installed on the line side of the HRVS-DN
Do not connect three phase voltage without starting
the HRVS-DN for more than 30 seconds.
Power Section Connections
• Line to terminals
L1, L2
and
L3
.
• By-pass to terminals
L1b, L2b
and
L3b
.
• Motor to
U, V
and
W
.
• Line and By-pass contactors must be used.
• Power Factor Capacitors, if required, should
be installed on the HRVS-DN line side (not
on the HRVS-DN Load side).
• Main supply must be applied in the correct
phase sequence.
• Bus bars and bypass contactor must be
arrange to maintain current flow through the
bypass after end of acceleration process.
Otherwise, current protection of the soft
starter will not function.
• Interlock the serial contactor - starting relay
with the “Fault relay” of the HRVS-DN.
