Enclosure requirements

General requirements

Megablocks may be mounted in hazardous (classified) areas – see section 8.  The 

following conditions must also be satisfied to ensure safe and reliable operation.

a) Prevent any form of pollution that could compromise the operation of the unit. 

For example, choose an unpolluted location or a suitable enclosure to protect the 

assembly.

b) Provide an adequate level of mechanical protection. This can be achieved by 

selecting a protected location, a suitable enclosure, or a combination of both.

c) Ensure that all cable entries and connections are secure by making provision for 

the careful routing and securing of all cables.

d) Provide adequate security against unauthorized interference.

e) Conform to the permitted ambient temperature range of –45°C to +70°C.

Outdoor mounting

In addition to the General Requirements above, if the Megablock is mounted in an 

outdoor location, use a suitable enclosure with a minimum of IP54 ingress protection.  

A higher level of ingress protection rating will be necessary if the working atmosphere 

is, or can be, corrosive, or if the enclosure is subject to wet or dusty environments.
