• Wire strip length 6mm (0.24in) recommended Class I Div. 2 (UL 1604)
Design details – for your advantage:
• All terminals are easy to reach as mounted on the front panel.
• Input and output are strictly apart from each other (input below, out-
put above) and so cannot be mixed up.
• Mounting and connection do not require any screwdriver
• A jumper (output terminal) serves to adjust the output voltage
(12V resp. 15V).
