RIOW REMOTE MODULES.
(CANOPEN
PROTOCOL).
5.4 Installation of the modules.
Place the modules on 1 profile, according to the European regulation EN50022 (DIN 35),
with 2 securing ends, one at each end of the group to help secure the modules. RIOW series
modules may be mounted horizontally or vertically; when mounting them vertically, use
additional mounting blocks at the bottom to secure the modules.
Ground connection.
The profiles on which the modules are mounted must be connected to the system ground
because some modules make contact with the profile to connect to ground. To connect the
profiles to ground, use a cable with a minimum section of 4 mm². To ensure contact between
the profile and the modules, the material of the profile must not be corrosive.
At the RIOW-PS24 module, the ground connection is done through the bottom pins of the
module. The ground connection is extended to the adjacent modules through the side
jumpers of the module.
Shield connection.
Proper shielding of the signal and data cables reduces interference and improves signal
quality while preventing measuring and data transmission errors. The cables must be
continuously shielded to ensure compliance with the technical specifications related to
measuring accuracy.
Ambient characteristics of the enclosure.
The temperature of the cabinet (enclosure) where the modules are mounted must not exceed
55 ºC (131ºF) when the modules are working. The heat dissipated by all the modules must
not exceed the heating capability of the cabinet where they are installed.
DO NOT make any connection or connect any module or cable if the group is under power. Before
making any connection, disconnect the power supply cable of the leading (first) module (RIOW-
CANOPEN) and, if necessary, that of the power supply module (RIOW-PS24).
Element Dissipated power
Leading (first) module. 2.0 watts.
Rest of modules. 0.8 W per module.
