Wiring instructions:
• Use suitable copper cables that are designed for at least the following operating temperatures:
+60°C for ambient temperatures up to +45°C and
+75°C for ambient temperatures up to +60°C and
+90°C for ambient temperatures up to +70°C.
• Observe the national installation rules and regulations!
• Make sure that all single wires of a strand are connected to the terminal!
• Do not use the device without PE connection.
• Unused terminals should be tightened firmly.
• Ferrules are permitted.
Series connection of power supply units:
Series connection (looping from one power supply output to the next) is permitted as long as the average
output current flowing through a connection pin does not exceed 54 A. For higher currents please use a
separate distribution terminal strip as shown in Fig.
