Page 9: Section 1: Introduction
Where external resistors are fitted to relays, these may present a danger of electric shock or burns, if touched. Front Cover The front cover provides additional securing of the relay element within the case. The relay cover should be in place during normal operating conditions. © 2022 Siemens Protection Devices Limited Chapter 1 - Page 5 of 38...

The only ‘action’ that is permitted is to reset the Fault Data display, latched binary outputs and LEDs by using the TEST/RESET button. Chapter 1 - Page 10 of 38 © 2022 Siemens Protection Devices Limited...
Page 15: Power Supply Unit (Psu)
The PSU does not contain any fuses or user serviceable protection components. Typically the PSU is connected to the auxiliary supply via an external HRC fuse rated at 6A (BS88/IEC60259). Isolation links may also be installed in accordance with user requirements. © 2022 Siemens Protection Devices Limited Chapter 1 - Page 11 of 38...

Page 24: Section 3: Voltage Monitoring Functions
Although a wide range is provided for live and dead voltage detector elements, the user must ensure that the live and dead zones do not overlap. Figure 3-1 VT Level Mode: 2 State Chapter 1 - Page 20 of 38 © 2022 Siemens Protection Devices Limited...
Page 25: Vt Level Mode: 3 State
This mode applies a 3% hysteresis setting to the drop off on both thresholds, to minimise ‘chattering’ of the element with frequency excursion.
