Removing The Control Panel - Thermo Scientific DSP2 Installation And Operation Manual

Removing The Control Panel

Before removing the control panel insure that the
MAINS SUPPLY is switched OFF. Either remove fuse
F1 from the power supply or shut down power source
to the metal detector.
The control panel is mounted on the search head
( or remote box ) with four mounting bolts. Remove
these bolts to gain access to internal connectors.
The power supply and search head cables are wired
into 'quick disconnect' connectors. It is not
necessary to remove the wires from these connectors.
When removing the connectors be careful not to pull
on the wires, pinch the connector and pull.
