1.2 Poper Use and Safety Conditions

• Installation and connections should be established in accordance with the instructions
set out in the manual by authorized persons. Unless the connection is built properly,

device should not be operated.

• Before wiring the device up, make sure that energy is cut o

• Do not disconnect the POWYS current transformer connection before short circuiting
the k-1 tips of the current transformer somewhere else. Otherwise, dangerous high
voltages may emerge at the secondary tips of the current transformer.

• Use a dry cloth to remove the dust from the device/clean the device. Avoid using
alcohol, thinner or a corrosive material.

• Device should be engaged only after all the connections are made.

• Do not open the inside of the device. There are no parts which the users can intervene
inside.

SECTION 1 GENERAL INFORMATION

7

• Device should be kept away from humid, wet, vibrant and dusty environments.

• It is recommended to connect a breaker or automatic fuse (2 amper) between the
voltage inputs of the device and the network.

The manufacturing company may not be kept responsible for unfavorable
incidents that arise out of the failure to follow the above cautions.

1.8 Four Quadrant Representation

The angle(Ø) between voltage and current provides us information about the direction of energy
ow. A positive sign for active/reactive power indicates that active/reactive power is consumed. And
also a negative sign for active/reactive power indicates that active/reactive power is generated.

Fig. 1-5 Four Quadrant Representation

NOTE: If the signs of active and reactive power are examined, it can be defined the quadrant that
POWYS measures.

In order to understand P and Q signs in POWYS 10xx and POWYS 11xx, instantaneous displays for P
and Q must be checked.
If active power display is seem constantly, it means active power(P) is positive. If it is blinked, it
means active power(P) is negative.
If reactive power(Q) display is seem constantly, it means reactive power(Q) is positive. If it is
blinked, it means reactive power(Q) is negative.

NOTE: Signs of P and Q can be reached through modbus communication.

e.g.; P= +10kW, Q= +5kVAr => Quadrant-1

P= -10kW, Q= +5kVAr => Quadrant

-2

P= -10kW, Q= -5kVAr => Quadrant

-3

P= +10kW, Q= -5kVAr => Quadrant

SECTION 2 INSTALLATION

2.1 Preparing for Installation

The purchased product may not include all hardware options referred in this document. This
situation does not constitute an impediment to the electrical installation.

Assembly and related connections of the product, must be implemented by
authorized persons in accordance with the instructions of user manual.

The device must not be put into service if the operator is not sure that all connections
are correctly accomplished.

2.2 Mounting

POWYS 10xx and POWYS 11xx are replaced onto 35mm standart rail.

Before wiring up voltage and current ends to POWYS, you must be sure that the
power is cut.

The product is connected to current transformer(s). Before disconnecting current
transformer leads, be sure that they are short circuited elsewhere or connected to
a parallel load which has suiciently low impedance. Otherwise dangerously high
voltages will be induced at the current transformer leads. Same phenomena also
apply for putting into service.
