Datacom DFC-0115 Manual

DFC-0115
REACTIVE POWER CONTROLLER
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.
SAFETY NOTICE
Failure to follow below
instructions will result in
death or serious injury
 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.
INSTALLATION
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.
Current transformers must
be used for current
measurements. No direct
connection allowed.
