• When installed as intended and secured by the eight front panel mounting screws, the unit can withstand shocks
and accelerations. Unit must be installed such that it is supported fully along both bottom side edges of the
chassis, at least 2 inches in, by a suitable angle bracket on shelf.
CE Mark Specific Safety Requirements
• This equipment meets all applicable safety directives (as specified in prEN50178) required to qualify for the
application of the CE marking.
• This equipment must be installed in accordance with the applicable requirements, or prEN50178 and
EN60204-1 / IEC-204-1.
• This equipment is qualified to operate at Pollution Degree II and Insulation Category II.
• This equipment is intended to be powered only from a 208 VAC, 3 Phase (3 wire plus ground) service with no
neutral connection used. For use at other voltages, a safety isolation transformer must be used to power this
equipment in accordance with the requirements of EN60742 / IEC-742.
• The installation of this equipment must assure that the AC power input connector (UL/CSA) is not accessible to
the user/operator. Access may be gained only by a qualified service technician. AC Mains connector installation
must be in accordance with local requirements.
• This unit provides appropriate separation between all interface, mains and output circuits in accordance with
5.2.18 of prEN50178.
AC Interlock System
• The low voltage (24 VAC) safety interlock circuit is designed to disable the unit in the event of an interlock
fault condition. At a minimum, interlock protection is located at the removable top cover, bottom cover and RF
output connector safety cover.
• End user’s system should provide indication to the operator of the interlock fault condition.
• Low voltage power for the interlock circuit is supplied by a step down transformer located inside the unit. This
transformer is designed to provide safe low voltage operation and provide isolation from the main AC line.
Lockout/Tagout
Prior to performing system maintenance, repair or other service operations the generator must be locked out and
tagged out to prevent accidentally energizing the system.
The following steps should be performed only by a qualified service technician:
• Disconnect AC input power to the generator.
• Mount a suitable “Clamshell” type lockout device to the AC input plug such as a Hubbell # HLD2 or
equivalent. Follow all manufacturers’ directions for the lockout device.
• Secure the lockout device with an appropriate padlock or safety lock.
• Apply a lockout warning tag to the lock out device.
The Lockout / Tagout device should not be removed until system service is completed and it has been determined
appropriate to reconnect and operate the generator.
