Connections at the measuring access port
• At the inner side of the measuring access port you can solder up to 9 cables. The inside connections
must be insulated against each other and against ground. Use 300 °C / 572 °F solder.
• The 9 contacts are conducted outside via the measuring access port. You can use them to connect a
device via the delivered plug.
Maximum load capacity of the switching contacts: 42 V AC/DC - 2A
DANGER
Electrical hazard.
Danger of death.
Damage to switching contacts and connection socket.
∅ Do NOT exceed the maximum switching load of 42 AC/DC – 2Amp.
∅ Do NOT connect any devices with a higher load capacity.
Insulate the inside connections against each other and against ground. Use 300 °C
572 °F solder.
