Note: Risk of property damage due to electrostatic discharge
Electrostatic discharges can destroy components on the board. Therefore, if you do
not have ESD equipment, touch the metal surround on the network interface before
opening the housing to establish equipotential bonding.
Some maintenance work requires access to the circuit board. For this purpose,
you can open the housing.

Dismantle the rule.box from the top-hat rail.
3.
Touch the metal surround of a network socket to perform equipotential bon-
ding.

Gently press the narrow sides of the rule.box housing together so that the
plastic lugs on the long sides of the bezel detach from the body of the
housing.

tory settings.

vice.
