Connectors
The four instrument connectors are of the plug-in type. They plug into the housing from top or bottom and click in posi -
tion (audible latching). Releasing the connectors should be done by means of a screwdriver.
Two connector types are available:
•
Screw terminals for max. 2,5 mm
2
conductors
•
Spring-clamp terminals for max. 2,5 mm
2

Before handling the connectors, the unit must be disconnected from the supply
voltage.
Tighten the screw terminals with a torque of 0,5 - 0,6 Nm.
With spring-clamp terminals, stiff and flexible wires with end crimp can be introduced into
the clamping hole directly. For releasing, actuate the (orange) opening lever.
