General
With our DC-MULTISER devices, dc current, voltage, active power and active energy may be measured. Moreover,
double-sided (positive-negative) current may be measured. The device allows the total, positive and negative operation
times to be monitored separately.
Before enabling this device, please read this manual carefully for the safety of both your system and yourself.
Please do not take any actions before contacting our company for any ambiguous matters.
Fields of use
Assembly Instructions
1- 1-Before starting the assembly of the device, ambient temperature and
humidity of the assembly location should be checked.
Otherwise the device may get damaged.
Storage Temperature: -10C....+70C
Ambient Temperature: 0C........+50C
Humidity: %15 - %95 (without condensation)
2-It should be taken care to ensure that the switchboard on which the device is to be
mounted should comply with IP20
3-The device should be mounted on the assembly rail inside the switchboard.
4-Please allow a clearance of at least 50 mm between the front side of the device
and the switchboard cover or protection sheet.
Making the connections
The connections of the device should be made when the device is deenergised.
The device should be connected as shown in the connection diagramme.
Please make the RS485 connection
Please do not energise the device before carrying out a check for all the connections by means of a gauge.
Current and voltage terminals comply with cables with a max. Cross-section of 2,5mm2
Pulse outputs, inputs and RS485 terminals comply with max. 1,5 mm2 cables
CAT5 (category 5) cable is recommended for RS485 connections
If the system presents power quality problems, insulation transformer or EMC filter should be used
for auxiliary power supply.
Connections
Current Connections
Please connect the load before shunt resistance. The load should be serial connected to the shunt resistance. One end
of the shunt resistance should be connected to the load and the other end to the negative of the system.
Current and voltage inputs are
completely insulated from the system.
Secondary value of the shunt
resistance may vary between
50mV and 100mV. The relevant
value should be set from the
menu of the device.
Voltage Connections:
Measurement range for UH and
UL types 0-300 Vdc
Measurement range for OH and
OL types 0-300 Vdc
