Plugging Precautions
Any Cat. No. 413 suppressor module can be removed and replaced with the power applied. However it will
only take on the settings determined by its remote contol unit after every control on the remote has been
exercised.
Similarly, the remote controls can be plugged and unplugged with the power on although it has been found
that the normal bypass indicator can occasionally get out of sync with the front panel LEDs if the
reconnection is not made smoothly.
The 34-way ribbon cable between the 430 control unit and the supressor module frames should NEVER be
plugged or unplugged with the power on (from either the control unit end or any of the module frame ends).
At best the unit will stop responding to controls and need to be powered down and back up to reset the
processor and at worst SERIOUS DAMAGE can be caused.
