II. Safety instructions
The following instructions are for your own
safety and must be observed under all
circumstances:
• Please read safety notes and following
installation instructions before
connecting the unit.
• Keep the installation instructions care-
fully stored for later reference.
• The unit is only intended for permanent
connection to the power supply circuit.
• All connection work is to be carried out
by a qualified technician.
• An easily accesible all-pole dis-
connecting device with 3mm minimum
contact gap width is to be installed near
the unit so that it can be disconnected
for service work.
Earthing must be low-resistance in
compliance with DIN 0100.
• All DIN 0805 requirements must be met
when installing. The individual wires of
the supply cable are to be fitted with
connector sleeves. The mains cable is
to be fastened in the housing so that it
cannot come into contact with any
secondary cables (see section IV).
