Installation
Warning
!
The system must be properly grounded.
The electrical installation must include a fuse and an easily accessible, all-pole
switch to fully disconnect the device from all power.
Before beginning the installation or performing maintenance work, the device
must be switched off and secured against an accidental power on.
When connecting the device, make certain that the mains leads in the device
are appropriately clamped to prevent short-circuits caused by torn wires.
The wires used to connect the device must have a cross-sectional area of at
least 1.5 mm
Low Voltage
Caution
!
With the external 24 V supply, make certain that the low voltage is electrically
isolated from the mains. Only use power supplies that are manufactured in
accordance with IEC 364-4-41 or HD 384.04.41 (VDE 0100, Part 410)!
The supply voltage may only lie within the specified voltage range. If it is not,
the possibility of functional failure on the part of the unit can not be excluded.
Note
The external 24 V supply is not electrically isolated. The 0 V line is connected
to the protective earth (PE).
After the 24 V supply is switched off, the device must be booted again.
