the possible effects of noise, and affords protection against lightning and static discharge.
An optional lightning-protection terminal block can be installed in place of the non-
lightning terminal block for Transmitters that will be installed in an area that is highly
susceptible to lightning strikes.
Note:
The lightning-protection terminal block is red, the regular terminal blocks are black.
