Earthing materials
Strap clamp, terminal
With the terminal AM3 it is possible to connect Cu-conductor, max. 35mm², to the earthing strap PP36. Earthing
strap PP36 is tightened with the strap clamp AM2. The distance between the screws is 10mm. The terminal and the
strap clamp are made of zinc-plated and yellow passivated steel.

AM2 6410050260950 Strap clamp for the earthing strap PP36 20/100
AM3 6410050260967 For the earthing strap PP36 20/100
Earthing strap
The earthing conductors, max. 35 mm² Cu, are connected to the various pipework using an earthing strap PP36 with
a strap clamp AM2 and terminal AM3. In case a 50 mm² or 70 mm² Cu-conductor is connected to the earthing block,
both ends of the earthing strap must be pressed together with the terminal to get sufficient conductivity. The
earthing strap is made of tinned annealed copper 1,5 mm thick. Lenght 1 m.

Potential equalizer bars
The potential equalizer bars are intended for the connection of system earthing conductors in buildings. Into AM4
it is possible to connect 8 pcs max. 50 mm² and 2 pcs max. 70 mm² conductors. Into AM5 it is possible to connect
5 pcs max. 50 mm² conductors. Both bars are made of tinned copper and fitted with zinc-plated steel screws and
tracking-resistant thermoplastic spacers.

AM4 6410019130959 Potential equalizer bar, max. 70 mm² Cu 5/50
AM5 6410019130966 Potential equalizer bar, max. 50 mm² Cu 5/50
Protective cover
In surface mounting, a cover PMR576 is used to protect AM4 and AM5. The cover has provisions for the conductors
to fit to the bar’s spacing and it is fixed on the wall with two screws.

Earthing terminal
The earthing terminal AM9 is mainly used to connect earthing conductors to various kinds of pipework, in sizes
Ø6-15 mm. The earthing terminal can also be used to connect earthing conductors to a building’s concrete reinforcement.
A suitable concrete reinforcement bar has a diameter of between 8-15 mm. The earthing conductor has one 4-35 mm²
terminal. If there is a need for a 25 mm² copper connector, two AM9 terminals must be used in parallel. The conductor bar
is made of tinned copper and the terminal is made of zinc-plated, yellow-passivated steel.

AM9 6410019130492 Earthing terminal D = 6-15 mm 1/50
Earthing terminal
The AM11 earthing terminal is used, for example, for the potential equalization of air-conditioning and ventilation
ducts. The earthing terminal has a single 10 mm² Cu-terminal. The terminal bar is made of tinned copper. It is affixed
with two pull rivets (pop-rivets), Ø3,2 mm, in the air-conditioning or ventilation duct and the protective lead is
connected to the connector attachment point. The conductors having a cross-section of Cu 1,5-10 mm² are suited to
a conductor connector equipped with conductor protection.
