Professionals must handle these areas. Iskra, d.d. does not take on responsibility for the use and installation. The energy meters are CE‐marked according to the LV‐directive and EMC directive for housing and light industry, which normally covers the most common use of the energy meters. Before energising the equipment, the following should be checked: Voltage rating and polarity; Current transformer (CT) rating and integrity of connections; For WSx30x the recommended maximum rating of the external protective fuse is 6A; Important: CT must be short‐circuited, before the wires are moved from terminals on the EM. Electric energy meter – WSxx0x ‐ User’s Manual 3 Contains of delivery CONTAINS OF DELIVERY The delivery contains: ‐ Energy meter WSx10x or WSx30x ‐ Quick guide 4 Electric energy meter – WSxx0x ‐ User’s Manual TYPES TYPES These meters are divided, according to their features, into more groups, each with its own qualities. WSx30x is transformer (x/1A, x/5A) operated group of energy meters with optional RS485 communication and MODBUS protocol, tariff input and pulse output. Group WSx10x has the same features as WSx30x, but direct connection up to 65A. The energy meters can be divided also according to the way in which energy is shown. WS0x01 meters have 7‐digit energy counter, WS0x02 meters have two 7‐digit energy counters and finally WS1x02 meters have 2x9 ‐ digit LCD display. Electric energy meter – WSxx0x ‐ User’s Manual 5 Connection CONNECTION Meter terminals are positioned on the bottom and the top side of the meter and are covered with the protection cover. Labels with connection diagram are located on the bottom of both covers. Current and voltage inputs are located on the bottom side as shown on the picture bellow. At direct connected meters WSx10x voltage inputs are equipped with protection bung, which allows you to physically break contact, before connecting or disconnecting voltage to the instrument and for test purposes. On the top side are connection terminals for communication, pulse output and tariff input. Regarding to the meter version either 3 or 4‐wire connection can be used. Drawing of the terminals 3‐wire connection for WSx10x (3u) 4‐wire connection for WSx10x (4u) 3‐wire connection for WSx30x (3u) 4‐wire connection for WSx30x (4u) 6 Electric energy meter – WSxx0x ‐ User’s Manual CONNECTION Connection of auxiliary circuits (the same for all versions) Connection of the tariff inputs On the top side are connection terminals for tariff input (terminals 13, 15, 33). With two tariff inputs can be selected up to four tariffs. Tariff inputs are galvanic isolated from other circuits. Connection of the pulse outputs Pulse outputs are used for external control of the consumed energy and for testing. A number of pulses depend on consumed energy. Connection of the communication For RS 485 communication the PC will require either an internal RS 485 communication port or an external RS 232 / RS 485 interface. Conductors A and B should be terminated with a 120 Ω terminating resistor at the end of a string.
