CABLE LENGTH
The standard cable length from the module to the consumer
(BSK, ERK, RM) is 1 m including prepared connection option.
The max. cable length from the module to the bus line is 1.5
m.
The total cable length from the switch cabinet to the last
terminal of the EasyF module with 128 modules must not
exceed a length of 1000 m.
Moreover, a distance of at least 5 cm between two flat cables
is recommended if cables are installed, for example in ducts,
tracks, etc.
MODULE MOUNTING
To ensure connection, a minimum distance of 40 mm from
the four side surfaces to walls, ventilation ducts or similar is
recommended.
For removing the module cover, a minimum distance of 100
mm from the top side of the cover is recommended.
In addition, it is recommended to fasten the module at a
distance of max. 100 mm from edges of the inspection
opening to provide a good accessibility to the module during
commissioning or service activities.
FLAT CABLE SYSTEM
H corresponds to the cable thickness
R corresponds to the smallest recommended bending radius
When using the connection socket (-MASD), it is
recommended to fasten it using cable ties or the like.
The recommended distance between points for fastening of
the flat cable is between at least 500 mm and a maximum of
1500 mm.

The cable manufacturer always recommends to use an
additional strain relief by means of cable ties (see figures).
This reduces the tractive forces at the connection socket.
According to EN 61535 A1, tractive forces of 100 ±2 N are
allowed for a cable diameter of more than 16 mm.
SWITCH CABINET MOUNTING
When mounting the EasyS-W01 or –W02 switch cabinet, the
minimum distance of 0.8 m from the ground is
recommended. A minimum distance of 0.2 m (on the right or
left) is also recommended. This distance from a side surface is
also recommended for the EasyS-A01 to –A05 switch
cabinets.
For fastening the EasyS-W01 to W02 switch cabinets, select
the corresponding fastening material depending on the
masonry.
