5.4 Preparatory work before installation
NOTE:
The leakage current is greater than 3.5 mA. A protective
conductor connection must be established before commissioning;
the use of RCDs alone is not permitted.
For the set output voltage, see section 4, Technical data.
5.5 Installing and mounting
NOTE:
The device contains reinforced smoothing with large electrolytic
capacitors in the output. If the de-energized capacitors are
connected to the battery by inserting the DC isolator or the DC
fuse, this results in a large charging current surge.
This can be avoided by switching on the appliance before
inserting the isolator and charging the capacitors to the appliance
output voltage. The DC isolator or fuse can now be inserted. The
input and output circuits of the appliance contain capacitors that
may still be live after the mains voltage has been switched off
(discharge time longer than 1 minute). Therefore, before removing
the device, check that the terminals are voltage-free and, if
necessary, discharge them via an external resistor at the mains
terminals or the L+ and L- terminals.
ATTENTION!
Risk of burns due to high heat sink temperature (> 65 °C).
Do not cover the heat sink and ventilation openings.
Do not touch the heat sink area during operation.
Allow the appliance to cool down before removing it.
5.5.1 Mains connection X1
DANGER!
Risk of electric shock!
Before carrying out any work on mains connector X1 or
mounting/unmounting the device: Disconnect mains,
prevent reconnection and check that all poles are de-
energized.
Do not make or break connection while energized.
A minimum protective conductor cross-section of 2.5 mm² is required
for the mains connection to X1. If this is not the case, the additional
earthing connection next to X2 must be used (minimum cross-section
10 mm² Cu).
