- Page 2 Hardware Physical Installation 1. The WattsOn-Mark II Metering Kit (“W2KIT”) is supplied in a polycarbonate enclosure. The only enclosure carries a NEMA 4X panel when ordered without the optional front panel LCD. 2. The enclosure includes mounting flanges. The flange dimensions are described in detail on the back of the enclosure itself.

- Page 4 LCD. While it may be used to power other equipment, it is important to consider the maximum output of the power supply (indicated on the power supply unit). The power consumption of the WattsOn-Mark II and LCD is approximately 400mA @ 24VDC. Voltage Inputs Line voltage to the voltage sensing inputs (Va, Vb, Vc) should be fused.
- Page 5 By default, the Modbus address is set to “1”. This may be easily changed via the DIP switch on the meter itself to address 1-15 (1-“F” respectively on the DIP switch). If a higher Modbus address is required, it may be set via the LCD menu (or via software). Refer to the WattsOn-Mark II User manual for more details.
- Page 6 The password may be changed via the “Password Settings” page. It is recommended to change the password so that the meter settings cannot be changed via the LCD in the future. If the password is lost, it must be recovered using a special procedure (contact Elkor for more details). Meter Settings To enter the “Meter Settings”...

- Page 8 The WattsOn-Mark II allows for CT Ratio and Phase shift values on a per-channel basis, however the LCD only allows entry of the parameters on a global level. In this case, it is suggested to use the average value, since they tend to be fairly uniform among a CT model.
- Page 9 Va. The same rationale should follow for phase B and C respectively. If it is impractical to do this, Elkor provides an online “phase-swap” calculator which allows the user to simulate swapping CT phases to observe the effect.
