Solenoid Drive
Series MG…X, MG…-A.X
With - protection for intended use in ex- zone 1
in accordance with 2014/34/EU (ATEX 95)
Operation
100% ED are permitted even in case of the most unfavourable ambient conditions.
DANGER!
During continuous operation the solenoid drive may get hot. Don‘t touch,
danger of injuries!
During operation it must be guaranteed, that neither the maximum permitted ambient tempera- ture or
of the fluid nor the load limit (excess voltage) will be exceeded. If necessary the solenoid drive has to
be protected against overcharging. All solenoid drives are wired with a varistor. To avoid induced
voltage, which may cause damage within the installation, the user must possibly provide additional
protective measures, which go beyond the installed varistor.
Dismounting of the solenoid drive
ATTENTION!
Disconnect the circuit before opening or, respectively, removing the
soleno id drive and wait at least 120 minutes.
DANGER!
During continuous operation the solenoid drive may get hot. Don‘t touch,
danger of injuries!
Loosen cylinder head screw (910/3) and remove it including lock washers (905/3). Remove so-
lenoid housing cover (105) from Ex-chamber cover (127). Disconnect the connection cable
from the clamps of the line duct (733). Loosen the cylinder head screws (910/2) and remove
them with the lock washers (905/2).
CAUTION!
The Ex-chamber cover (127) must not be disconnected from the
solenoid housing (103) by means of a screw driver or any other pointed
tool.
Lift the Ex-chamber cover (127) from the solenoid housing (103). Loosen the conductor line of
solenoid drive MG..x at the connection clamp, or respectively, in case of solenoid drive MG..
