Installation
WARNING:
Electrocution hazard. To avoid personal injury or
death from electrocution, remove all sources of power and
allow stored energy to discharge before installing or removing
equipment.
Caution:
For general guidelines on system planning, design,
installation, commissioning, use and maintenance, refer to the
EN 54-14 standard and local regulations.
Installing the mounting base
Surface mount the base using 2 x M4 screws (not supplied).
Wiring
Wire the mounting base as shown in Figure 1 (standard
installation with end-of-line resistor) or Figure 2 for the diode
base (BS 5839-1 installations with active end-of-line
termination).
