Connections
The amplifier and network module housed in the rear of the cabinet is protected by a weatherproof canvas cowl. This vital
accessory has two functions. In the event of poor weather it will keep all electrical connections dry. In the event of very hot
weather it acts as a sun shade to keep direct sunlight off the amplifier cooling system and thus prevents over-heating.
The cowl travels folded flat for ease of transportation. It is held in the operating position by two triangles of canvas mounted
towards the middle of the cowl. These have straps attached and by pulling the straps the cowl pops up into position and is held
in place with the two supporting triangles which connect to the inside of the cowl using Velcro. To fold the cowl flat, the straps
are again used to pull the supporting triangles down left and right.
Mains
The mains inlet to the MLD in common with all larger format MLA series enclosures is a 16A male 230V Ceeform inlet connector.
As the MLD is always going to be at the bottom of an array and will always be at 13.75⁰ to the MLA cabinet above it in an arr
ay
which may already have a steep curve, the mains inlet may be angled upwards making ingress of water a possibility where
systems are deployed outdoors. This could easily occur due to rain running down the mains cable and then to the mains
connection. Whilst the Ceeform connectors have an IP67 rating the MLD features an additional weatherproofing measure in the
form of a canvas bag in which the mains inlet is housed. Once the in-coming mains connector is mated with the inlet, the draw-
string around the opening of the bag is pulled tight around the cable to seal it from water ingress. The string has a button-press
release catch to hold it closed.
