Accessing the DIP switches
Dangerous voltages and currents are present in the active converter
When power is applied to the converter, even when it is not active, dangerous levels of
voltage and current are present in the system.
Before attempting the removal of any components of the system the following steps should
be taken to ensure that the system is completely safe:
1. Ensure that the converter is not running, if so, the converter must be stopped.
2. Disconnect all mains power supplies to the system. If an external 24 V supply is
3. Wait 5 minutes to allow all the residual current and voltages to dissipate fully.
Generally the G110M system is delivered fully assembled on a motor which prohibits easy
access to the DIP switches. To access the DIP switches it is necessary to remove the Power
Module; this action is illustrated in the figure below.

Description of the DIP switches functions
When the DIP switches are in the OFF position, the value of the function is defined by the
default value of the parameter. If the DIP switch is activated for a specific function, then the
parameters for that function cannot be modified by manually editing the parameter value, i.e.
ready-only.
