3.5 - WGC TRANSFORMERS
The transformer is designed for wall-mounting or DIN-rail assembly with an accessory for installation.
The WGC is a feed-thru busbar type transformer, where the conductor cables to be measured must
pass through the inner hole or window of the transformer.
3.5.1 PANEL INSTALLATION
For panel installation, 4 clamping clips are provided with the transformer, see Figure 6.
Figure 6: Clamping clip.
The clamping clips must be installed on the WGC, as shown in Figure 7.
