The cover of the Isomag switch
hinges down to allow access to
the fixing holes. Unscrew the 2
cover retaining screws using the security key supplied and
swing down the cover. The internal plastic cover protects the
electrical contacts and the ISOMAG Insulating Barrier.
The ISOMAG 4 can be fitted in any position on hinged,
sliding or lift-off guards.
The switch will accommodate inaccuracies in the guard or door but it should not
be used as a guide. When correctly installed the bottom of the actuator tongue
should clear the entry hole by 1mm. When the guard is closed there should
be a gap of 3 to 6mm between the actuator and switch faces.
On hinged guards the
minimum radius from the
hinge point to the actuator
tongue centre
should be as
shown.

Hinge down the cover to gain access to the
mounting holes. Mount the switch on the
stationary section of the guard using 2 x
M5 fixings. Use mounting brackets if
necessary.
Mount the actuator on the moving guard
section with the actuator tongue centrally
opposite the switch entry hole. Use the
two security screws provided. The
elongated holes allow adjustment before
fully tightening the screws.
The guard door
must be fitted
with a stop to
ensure a gap of
3 to 6mm. The
actuator MUST
NOT be allowed
to strike the
switch when the
guard door is
closed.
