The outer box of HISO3-20 (Figure 6-5 to Figure 6-7) (manufacturer: Rolec; series: Alu-Kom;
part number: AKH311) offers an outside screw-terminal for earth connection (see Figure 6-7).
The box dimension is 402.5 x 310 x 180 mm³. It is made of aluminum with polymer-coated
surface. The SISO3 modules are clamped on a DIN rail. Cables enter on two sides over two so-
called cable entry systems (see Figure 6-6 and Figure 6-7). A label nearby the cable entries
identifies the Ex i cable entries (Figure 6-7) and the non Ex i cable entries (Figure 6-6
.
The cable entry system consists of a frame for up to 5 inserts, each insert (21 x 21 x 19 mm³,
icotek KT4/5 #39908) allowing inserting up to 4 cables of 5 mm diameter each. Internal cable
c
hannels are prepared to feed the AE system from one side, ending at the SISO3s’ BNC plug,
and the Ex i cables to the sensors from the other side, ending at the SISO3s’ SMA plug.
