The DFC-0115 is an advanced, precision
15 step power factor control and metering
device, which continuously matches the
target cosø value of the load.
Installation and configuration of the DFC-
0115 is very simple thanks to the auto-
learning function.
Each step output supports single-phase,
two-phase, and three-phase connection of
capacitors and reactors.
Electrical equipment should be installed only
by qualified specialist. No responsibility is
assured by the manufacturer or any of its
subsidiaries for any consequences resulting
from the non-compliance to these
instructions.
Check the unit for cracks and damages due
to transportation. Do not install damaged
equipment.
Do not open the unit. There is no
serviceable parts inside.
Fuses of fast type with a maximum rating of
6A must be connected to the power supply
and phase voltage inputs, in close proximity
of the unit.
Disconnect all power before working on
equipment.
When the unit is connected to the network
do not touch terminals.
Short circuit terminals of unused current
transformers.
Any electrical parameter applied to the
device must be in the range specified in the
user manual.
Do not try to clean the device with solvent or
the like. Only clean with a dump cloth.
Do not allow water to come in the unit.
Verify correct terminal connections before
applying power.
Only for front panel mounting.
Before Installation:
Read the user manual carefully,
determine the correct connection
diagram.
Remove all connectors and mounting
brackets from the unit, then pass the
unit through the mounting opening.
Put mounting brackets and tighten. Do
not tighten too much, this can break
the enclosure.
Make electrical connections with plugs
removed from sockets, then place
plugs to their sockets.
Make sure to use adequate fuses.
Do not subject the unit to water spill.
Below conditions may damage the
device:
Incorrect connections.
Incorrect power supply voltage.
Voltage at measuring terminals
beyond specified range.
Current at measuring terminals
beyond specified range.
Overloaded or short circuited relay
output terminals.
Below conditions may cause abnormal
operation:
Power supply voltage below minimum
acceptable level.
Power supply frequency out of
specified limits
Phase order of voltage inputs not
correct. (Without auto-correct function)
Current transformers not matching
related phases. (Without auto-correct
function)
Incorrect current transformer polarity.
(Without auto-correct function)
Inappropriate delay for switch on,
switch off delays of steps.
REACTIVE POWER CONTROLLER
Failure to follow below
instructions will result in
death or serious injury
Current transformers must
be used for current
measurements. No direct
connection allowed.
