DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
If the supply cord is damaged, it MUST be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
CAUTION
Do NOT push or place redundant cable length into the unit.
NOTICE
The distance between the high voltage and low voltage
cables should be at least 50 mm.
6.1 About electrical compliance
For the models EGSAH/X06+10(U)D▲9W▼(G), the following
statement…
Equipment complying with EN/IEC 61000‑3‑12 (European/
International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public low-voltage
systems with input current >16 A and ≤75 A per phase.).
…is valid in the following cases:

6.2 Safety device requirements
Power supply
The power supply must be protected with the required safety
devices, i.e. a main switch, a slow blow fuse on each phase and an
earth leakage protector in accordance with the applicable legislation.
Selection and sizing of the wiring should be done in accordance with
the applicable legislation based on the information mentioned in the
table below.
Make sure that a separate power supply circuit is provided for this
unit and that all electrical work is carried out by qualified personnel
according to local laws and regulations and this manual. An
insufficient power supply capacity or improper electrical construction
may lead to electric shocks or fire.
