EMERGENCY SHUTDOWN
The machine is fitted with two emergency stop push button control switches
(one at the front right corner of the machine and one on the left side of the
machine above the rails). Pressing either of these push-buttons (or opening the
machine access covers) cuts the power supply to all motors and selected
actuators. A warning of this condition is reported on the machine monitor.

FRAME COVERS
In order to protect personnel and prevent damage to the machine, six panels
are fitted around the base of the machine. These panels (listed below) may be
removed to assist maintenance.
• Front Panel
• Side Panels - Front (2 positions)
• Side Panels - Rear (2 positions)
• Rear Panel
Removal of the front and rear panels requires a maintenance key to release two
locking mechanisms located externally at the top corners of each panel (Panel
Locking Mechanism figure refers).
The two side front panels on each side of the machine are slid forward of their
internal support lugs at the bottom of the machine, (providing that both the
individual internal quick release fasteners have been released).
NOTE
The front left side panel cannot be removed with the MMI Assembly in place.
For removal of the ergo arm mount, see Removal of the MMI Assembly - Major
Relocation - Transport chapter of the Technical Reference Manual.
The two side rear panels on each side of the machine are slid to the rear of their
internal support lugs at the bottom of the machine, (after the rear panel has been
removed) and their individual internal quick release fasteners (2 positions) have
been released.

Enclosures Enclosures are not fitted with a safety interlock. Inadvertent access to such
enclosures is prevented by the presence of the enclosure panels and the frame
covers. However within enclosures, care has been taken to ensure that
electrically live components are covered.

SAFETY FEATURES
HIGH VOLTAGE PROTECTION
Chapter Issue 1 Oct 02 Installation Manual 2.5
HIGH VOLTAGE PROTECTION
Mechanisms The machine incorporates Class 1 electrical protection according to the IEC 536
requirement 1:1993.
All machines prior to shipment undergo electrical safety tests as described in
EN60204-1 (1997) Section 19:
• 19.2 Continuity of the protective bonding circuit
• 19.3 Insulation resistance test
With the exception of the optional Onboard Suction Filtration Unit, machine
mechanisms are powered by voltages less than 50V.
NOTE
Refer to Machine Preparation chapter (Machine Relocation section) for infor-
mation on Vacuum Filtration Unit checks.
Access Where incoming supply voltages are present, protection is afforded by control-
ling access to the enclosures that house the supply. The machine is fitted with
a mains isolator switch that cuts power to all circuits located beyond the switch
on both incoming and outgoing power terminals. The isolator switch is located
at the front of the machine.
Hazard Warning
Labels
Hazard warning labels are placed on the outside of enclosures where danger-
ous voltage (100V-240V) terminations are present within.
Earth Bonding All external metal surfaces are mechanically and electrically bonded to the
machine earth point. The bonding wire used is identified by its green and yellow
insulation and is commonly used to earth bond throughout. Care should be
taken when removing these links that when they are replaced they are secured
tightly and cleanly.
