INSTALLATION
The PRO EM235 is designed exclusively for installation on DIN-rail.
Please note to leave room for future expansion: when installing a basic unit
(without modules), it is recommended to maintain a minimal gap of 30-100mm to
the right of the unit, allowing future installation of additional detachable SATEC
modules (figure 5; depending on number of added modules, 17.8mm each).
Figure 2:
Opening the latch
Use a flathead screwdriver to dislodge the unit
from the rail by inserting the screw-driver into the
slit in the latch, pushing the latch downwards. To
install the unit push the latch back upwards.

ELECTRICAL CONNECTIONS
The following steps (Figure 3) correspond with a low-voltage three phase network:
1. Make sure all power sources are disconnected.
2. Make sure that your designated power supply corresponds with the unit's rating.
3. Connect the power supply (bottom-left of front panel) via 12 AWG wires and a
designated circuit breaker.
4. Standard external current transformers: connect the CT's (14 AWG minimum) "+" pole to
the device's I1+ current input (unit’s bottom right of front panel, as in figure 3) and the "-
" pole to the adjacent I1- current input. Repeat this for the following two phases, I2 and
I3. Verify proper polarity in your connections in accordance with the arrow printed on
the external CTs.
“HACS” CTs: connect the red/white wire to the "+" terminal and the black/orange (colors
vary according to the CT model) wire to the "-" terminal.
5. Connect the voltage measurement inputs (22-12 AWG; bottom-center of front panel).
6. Connect the com wire (26-12 AWG, shielded) to COM1 (RS485, top-left of front panel).
7. Power-on the unit.
