Chapter 2 – Safety Information
Terminals exposed during installation, commissioning
and maintenance may present a hazardous voltage
unless the equipment is electrically isolated.
Tighten M3 clamping screws of heavy duty terminal block
connectors to a nominal torque of 1.0 Nm.
Tighten captive screws of header-type (Euro) terminal blocks
to 0.5 Nm minimum and 0.6 Nm maximum.
Always use insulated crimp terminations for voltage and
current connections.
Always use the correct crimp terminal and tool according to
the wire size.
In order to maintain the equipment’s requirements for
protection against electric shock, other devices
connected to Reason Switches shall have protective class
equal or superior to Class 1.
Watchdog (self-monitoring) contacts are provided to indicate
the health of the device on some products. We strongly
recommend that you hard wire these contacts into the
substation's automation system, for alarm purposes.
Ground the equipment with the supplied PCT (Protective
Conductor Terminal).
