The connection for 3x 400 V AC ... 500 V AC is achieved using the L1, L2, L3 and PE screw connections.
The device can be connected to 3-phase systems with nominal voltages 3x 400 V AC ... 500 V AC are connected. In the
event of a phase failure, unrestricted operation is possible with nominal capacity.
An operation in DC networks is also possible without any limitations.
ATTENTION
In DC applications, a suitable fuse must be wired upstream!
Connect not more than one power supply unit to a fuse or a power switch.
Suggestion: In AC connections, connect a maximum of one power supply unit to a fuse or a power switch.
In order to comply with UL approval, use copper cables with an operating temperature of > 75°C (ambient
temperature < 55°C) and > 90°C (ambient temperature < 75°C).

Protection of the primary side
The device must be installed in acc. with the regulations as in
EN 60950. It must be possible to disconnect the device using
a suitable isolating facility outside the power supply. Primary
circuit mains protection, for example, is suitable for this
purpose.
Required backup fuse (device and line protection)
External thermo-magnetic fuses are necessary for device
protection: 2/3 x 6 A, 10 A or 16 A power circuit breaker,
characteristic B (or identical function).
Connect a suitable fuse upstream for DC applications!
ATTENTION
If an external fuse is triggered, there is most
probably a malfunction in the device. In this
case, the device must be inspected in the
factory!
