Unlatching is done via:
•
Electromagnetic unlatching, remote-controlled
•
Manual unlatching via push rod or draw bar.
The remote tripping is carried out via the electromagnetic shunt release Y1 (9). If
manual unlatching (EMERGENCY STOP) via the push rod or draw bar is not avail-
able, the shunt release Y1 can be carefully manually actuated from the rear side of
the vacuum contactor in a de-energised state and for test purposes (see details in
Fig. 8).
Manually operated unlatching (EMERGENCY STOP) is performed with a push rod
or draw bar (12, 15) with approx. 30 N. The customer is to mount M4 threaded rods
for the push rod or draw bar with fitting end pieces or other suitable terminators.
Tightening torque 3 ±0.5 Nm.
If no latching or unlatching is available but is planned for backfit, the following mod-
ules can be subsequently ordered and mounted:
•
Mechanical closing latching with shunt release Y1
•
Manually operated unlatching mechanical system (EMERGENCY STOP) with
draw bar or push rod
See chapter "Mounting the mechanical closing latching (optional) and manual
unlatching (optional)", p. 29.
A description of the installation is only supplied with the operating instructions of the
retrofit kit.
