The plug-in power supply units may only be put into operation if
the housing is safely closed and screw-fastened.
Power packs are not approved for utilisation on human beings or
animals.
If one or several power packs are series-connected, hihgly dange-
rous voltages (> 35 VDC) are generated.
Power packs and the consumers connected to them must not be
operated without supervision.
Bright cables and contacts should not be laid. All these areas must
be covered by appropriate, flame-retardant insulating material or
other measures to protect them against direct contact. The electri-
cally conductive parts of the consumers connected must also be
protected against direct contact by appropriate measures.
If safe operation can no longer be reasonably assumed, the unit
must be decommissioned and protected against involuntary opera-
tion. Safe operation cannot be reasonably assumed if
- the unit shows visual traces of damage,
- the unit no longer functions and
- after extended storage under unfavourable conditions or
- after severe strain during transit.
Never connect your plug-in power supply unit(s) to the mains
straight after having taken it (them) from a cold into a warm atmos-
phere. Under unfavourable conditions, the condensate which might
develop may destroy your unit. Allow the unit to adjust to room
temperature without connecting it.
