4.2.
ASSEMBLY
- The unit is designed for mounting inside housings (control panel, switchboard)
insuring appropriate protection against surges and interference. Metal housings
must be connected to ground in a way that complies with the governing
regulations.
- Disconnect the power supply prior to starting assembly.
- Check the connections are wired correctly prior to switching the unit on.
In order to install the unit, a 90.5 x 43 mm mounting hole (Figure 4.1, 4.2) must be
prepared. The thickness of the material of which the panel is made must not exceed
5mm. When preparing the mounting hole take the grooves for catches located on
both sides of the housing into consideration (Figure 4.1, 4.2). Place the unit in the
mounting hole inserting it from the front side of the panel, and then fix it using the
brackets (Figure 4.3). The minimum distances between the centre points of multiple
units - due to the thermal and mechanical conditions of operation - are 115 mm x
67mm (Figure 4.4).
