If the device requires servicing of any kind, you may need to disconnect and
remove it from its mounting. The initial installation should be done in a way that
makes this as convenient as possible.
■ Voltage/Power lines should be properly insulated as well as other cables. Be
careful when handing to avoid tripping.
■ Do not under any circumstances insert foreign objects of any kind into the heat
dissipation holes located on the different surfaces of the device. This may not
only harm the internal layout but might cause harm to you as well.
■ Do not under any circumstances open the device casing for any reason. Please
contact your dealer for any repair needed or follow the instructions on your
User’s Manual.
