3.1.3 Instructions for Mechanical Installation
Hazardous voltage may be present.
In order to avoiding fluid spills shorting voltages within the converter,
place the controller in a spill protected environment (for example
protected electronic cabinets).
If explosive flammable gases are present, place the converter in an
explosion-proof cabinet.
1. The converter shall be installed in a spill protected cabinet.
2. Assure that enough ventilation is provided in order to avoid exceeding the allowed ambient temperature and
humidity range: Temperature range: 0–40°C (32–104°F). Humidity range: 30-85% R.H. (no condensation).
3. A wall-mountable extension cable (see Table 3 and Figure 11) is provided in order to panel mount the sensor
cable on the cabinet wall. Make a whole to the cabinet wall according to Figure 11. The gasket ring delivered
with the extension cable can be used on the inside of the cabinet wall hence achieving an IP-67 sealing.
4. For connecting the sensor to the wall-mountable connector on the cabinet the interconnect cable according to
Table 3 and Figure 9 can be used.
Step 1: Align first the Snap-Pin side of the converter with
the DIN rail corner (picture a). If the rigid side is
aligned first (see picture b) than some of the DIN
rail parts of the converter housing might be
damaged.
Step 2: Press in the converter on the spring-pin side (see
picture c).
Step 3: Press in the fix side of the DIN rail recess of the
converter housing (see picture d)
Step 4: Relax the converter and let the snap-pin fix it
(see picture e).
