2.2 Mounting
The WebLog120 housing is installed on a TS35 top-hat rail. The housing occupies 8 division units (8 DU) on
the rail and, due to its low overall height of 60 mm, not only fits in a switch cabinet, but also in a meter cabinet
under the cover.
The device requires an external mains voltage of 110 to 250VAC, which must be connected by an electrician.
Please protect the device with a suitable fuse. We also recommend installing a circuit breaker in the control
cabinet so that the mains voltage can be switched off for service purposes.
