2 .3 MTL7700 range – accessories
MTL7700 range of barriers mount directly onto DIN-rail. A
comprehensive selection of mounting, tagging, power and earthing
accessories is available. Installation details are given in section 4.3.
Essential accessories
The following are usually considered essential for mounting and
earthing MTL7700 range of barriers:
DIN-rail (eg, THR2 or THR7000)
Insulating spacers (eg, ISP7000)
Earth terminal (eg, ETL7000)
