3.6 Linking in series
Certain Slam®Hornet units may be equipped with Ex
–certified socket in the factory. Sockets
are considered as one option so they are adde
d to the unit upon customer’s special request.
In-built sockets are recommended when the illuminated area is notably large, complex or not
enough wiring points are available. Linking the units in series save time, amount of cable and
provide an opportunity to build a chain of lights to provide enough illumination in the darkness.
When linking Slam®Hornet
–lights together, please take the following steps:
1) If using transformer, ensure its condition and capability to supply correct amount of voltage, current and
power (VA)
2) Connect the first unit outside the Ex
–area
3) Then connect the other luminaries to each other one by one
4) The in-built socket is only for chaining Slam®Hornet units.
5) Fix them with accessories you have selected
6) Take the chain into Ex
–area
Amount of lights which may be connected with each other depends on the supply voltage.
Competent person of the operator shall control and accept the temporary electrical
installation at the site
.
Before connecting Slam®Hornet luminaries together, please ensure the following points.
1. The total length of the light chain does not exceed 66m. Please see additonal detail below the chart.
2. The total current of the electrical installation does not exceed 16A.
