5.
Use the three existing holes to
fix the housing back panel to the
wall: use three screws of a suitable
length for the thickness of the
wall on which the panel will be
mounted. Fit a rubber washer
(supplied) between each screw
and the housing back panel.
6.
Hook the front panel back up to
the lower part of the housing by
inserting the two hinges in their
seats and, bending them, rotate
downwards 180° to gain access to
the electronic board.
NOTE !
Make all the electrical connections as illustrated in the diagram for the corresponding model (see
drawing on page 16).
To effect correct electrical connection and maintain the protection rating, use appropriate wire/
raceway grips to ensure a good seal.
Route the wiring inside the unit in as tidy a fashion as possible: be especially careful to keep power
wires away from signal wires. Use clips to hold wires in place.
7.
Close the front panel, making sure
that all the wires are inside the
housing and that the housing seal
sits in its seat properly.
Tighten the front panel using the 4
screws, making sure the O-rings on
the head of each screw are used.
Power up the panel and carry out
thorough reading/programming
of all the parameters.
NOTE !
Be careful not to over-tighten the closure screws as this could warp the housing and compromise
proper operation of the membrane-type keypad.
Install short-circuit overload safety devices on all the power cables connected to the OPTYMA
TM
Control so as to prevent damage to the device. Work and/or maintenance must be carried out on
the unit ONLY after disconnecting the panel from the power supply and from any inductive/power
loads: doing so allows the worker to do his job safely.
If Modbus data communication
is connected, see the JUMPER
setting on page 14, preferably
before all the wiring is connected.
