Terminal compartment: open

SAREx 16.2 Control unit - electromechanical
KM version with additional support terminals (terminal blocks) via terminal carrier.
When using solid fieldbus cables in line topology, imperatively use support terminals.
Both versions (KT and KM) are available with terminal compartment in protection
type Ex e (increased safety) as well as in protection type Ex d (flameproof enclosure)
(refer to Ex marking on name plate).
Plug-in connection is made via the connection frame. For cable connection, simply
remove the cover. The connection frame with the cable entries remains within the
device. The flameproof interior of the connected devices remains sealed.
