The switch functions and the error monitoring influence the position of various relays.
The relay contacts can be used for switching via the RELAY terminal. The relay contacts
are isolated.
Dangerous contact voltage
Voltages above 30 V AC or 60 V DC are deemed to be dangerous in the event of contact
in accordance with EN 61010.
 Only apply a grounded protective extra-low voltage (PELV).
 Connect peripheral components with a shielded connecting cable (electromagnetic
compatibility) to the RELAY terminal on the back of the device.

2 n.c.
1) Fused with a PTC element at 200 mA, self-resetting after the device power-off or disconnecting of
the RELAY plug. Meets the requirements for grounded protective extra-low voltage.
The B-type USB port facilitates direct communication with the TPG 366 via a computer
(e.g. firmware update, parameter storage (read/write)).
