7. Operation and locking
a) Motorized operation
– Switch the “MOTOR”-switch to the ON position.
In this position both the local and remote
functions
operate.
– Use the control pushbuttons I or O for local
control.
b) Manual operation
Switch the “MOTOR”-switch to the OFF-position.
Pull the coupling ring out and operate using the control
handle. Some disconnectors will need a slight turn in
the other direction with the control lever before the
coupling ring A-4 can be pulled out. See also acces-
sories UEMZ 469.
c) Motorized operation after manual
operation
After manually operating the disconnector once, the
power unit is not in synch with the disconnector. The
coupling ring A-4 usually drops into place itself when
next using the motor operating device. To assist the
coupling ring relocating itself, turn the axel slightly
backwards after manually operating the disconnector.
If for example the disconnector is opened manually
and then it is to be closed using the motor operating
device, fi rst drive the motor operating device to the
open position so that the coupling ring drops into place
and then drive it to the closed position.
d) Mechanical locking
Switch the “MOTOR” -switch to the O-position. The
disconnector can be locked when the motor operat-
ing device is in the open or closed position, also after
manual operation, even if the coupling ring is disengaged.
Lock after pushing the locking catch A-5 in using
∅
6...10 mm padlock. The locking will also open the
electrical operating circuit automatically.
8. Maintenance
The operating devices threaded shaft and gearwheel
is to be greased at 5 year intervals or after 1000 ope-
rations.
Recommended grease type is Isofl ex Topas NCA 52
or similar synthetic low temperature resistant grease.
The grease can be ordered from the manufacturer of
the operating device.
If the operating device is fi tted with an anti-conden-
sation heater check that it works.
