4.1 Installation
The installation of the panel should be carried out by qualified personnel only. The electronic components within
the panel are vulnerable to physical damage and damage by electrostatic discharges.
It is advisable to wear a wrist strap designed to prevent the build-up of static charges within the
body, before handling any electronic circuit boards.
Never insert or remove boards or components with the power on. To avoid this hazard a Mains
Isolator Switch should be installed.
Mounting the Cabinet
The site chosen for the location of the panel should be clean and dry and not subject to shock or vibration. The
temperature should be in the range -5° to +35° C, the humidity should not exceed 95%.
Open the outer cover using the key provided.
Unplug the power terminal block from the left
hand side of the circuit board, remove the two
screws holding the plate in position and then
remove the complete circuit board and plate.
Hold the assembly by gripping the metal plate
only and try to avoid touching the circuit
board.
Place the plate/circuit board assembly and
fixing screws in a safe location to prevent
accidental damage.
The outer cover can be removed to make
fitting more manageable by removing the two
pins holding it in position on the left hand side.
Remove knockouts from the top and or back of
the box in the positions at which cables will
enter.
When surface mounting use the box as a
template, mark the position of the top-fixing
hole, ensuring that the wall is flat at the chosen
location. The top fixing is a keyhole slot and
fitting a screw here and hanging the box first
will assist in marking the remaining fixing
points.
Screws or bolts of a minimum of 5 mm
diameter and 40 mm long must be used to
mount the enclosure in all three mounting
positions.
After the box is firmly fixed, remove any
knockout blanks and dust or swarf caused by
drilling and fixing the box.
See bezel installation instructions if Semi or
Deep recess mounting.
