Even in the long-term test at 80°C there is no significant loss of mass due to corrosion.
Please note that the amount of antifreeze has a significant influence on the cooling effect and the
flow behavior of the cooling medium. In the case of mixing ratios with an anti-freeze content greater
than 1:10, a higher pump output is required in order to achieve the same flow through the ERS systems.
Electromagnetic Compatibility
ERS test bench energy systems are electrical equipment designed for use in industrial or commercial
applications. It
causes radio interference during operation (limit values according to EN
61000-6-4, se-
verity level 4). When used with a connected application, compliance with the specific safety regula-
tions and the handling of any radio interference are the responsibility of the owner.
The following rules for installation must be observed:
In order to prevent exposure to interference, separate mains and supply cables, motor cables, and
control and data cables. They should be installed at a minimum distance of 15
cm from each other.
Use only cables shielded with copper or tinned copper braiding; always clamp the shielding directly
to the equalizing rails (do not extend shielding with single-conductor cables)
Always equip inductive switching elements (contactors etc.) with suppressors such as varistors, RC
elements, or protective diodes.
Keep all connections as short as possible, and route them close to the reference potential; no free-
floating cables.
In case of unshielded cables, the forward and return conductors must be twisted to suppress sym-
metric interference.
