3. Installation
Installation of the units should be carried out by qualified personnel only. The electronic components within the units 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.
Mounting the boxes
The site chosen for the location of the units 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%.
Remove the front plate by taking out the two fixing screws and put them in a safe place for re-fitting later.
Remove knockouts from the top and or back of the box in the positions at which cables will enter.
Using the box as a template, mark the position of the fixing holes, ensuring that the wall is flat at the chosen location. Screws
or bolts of a minimum of 5mm diameter and 40mm long must be used to mount the enclosure in all mounting positions.
After the box is firmly fixed, remove any knockout blanks and dust or swarf caused by drilling and
fixing the box.
4. Cabling
Cables should be brought into the cabinet using the knockouts provided and where necessary, using
couplers to maximise the space within the enclosure. Use the knockouts closest to the terminating
position for each cable, to ensure cable length within the enclosure is kept to a minimum.
Ensure that only the numbers of knockouts are removed to meet the cable termination
requirements, as any additional apertures in the enclosure will compromise the IP30 ingress
protection.
Brass inlet bushings or cable glands should be used to maintain insulation and to ensure EMC
compliance. t
The screen or drain wires should be bonded to earth via metal cable glands.
The maximum size of cable, which can be terminated, is 2.5
2
mm.
The communications protocols are highly immune to noise but sensible segregation from known
noise generating sources such as mains cables is recommended.
