Candela Corporation AlexTriVantage Laser System
Ground Continuity Tests
The laser system requires a connection to earth ground to reduce the risk of electric shock.
To verify that this safety feature is functioning properly, it is recommended that continuity
between the laser chassis and mains plug grounding pin be checked annually at a minimum,
monthly if the laser is moved frequently, or before use if the line cord and/or power plug has
been altered or replaced. If unsure of which pin is “ground” on your particular power plug,
consult an Electrician for help. The following procedure verifies ground continuity:
1. Using the Ohms setting of a Volt-Ohm meter, set the scale to “x1”. Measure the
resistance between the plug’s ground pin and any unpainted conductive surface on the
laser chassis. This reading must fall between 0 – 0.1 Ohms.
2. A battery and light, or a battery and buzzer combination maybe be alternatively used to
verify a ground connection between any unpainted conductive surface and the plug’s
ground pin if an Ohm meter is not available. An adequate ground connection will be
indicated by the illumination of the light or sounding of the buzzer.
Environmental Requirements
Before installation, the intended site must be prepared as described in this section. The site
must have sufficient space to accommodate the laser system, must provide the proper
electrical power configuration and receptacles, and must meet the additional environmental
specifications.
Space
Sufficient floor space is required for the laser system. Approximately 15 inches (40 cm) of
clearance is required between the rear panel and the wall to allow room for the power cord
and proper circulation of air from the cooling vents.
Air Quality
Ensure that the atmosphere is non-corrosive, with no salts or acids in suspension in the
air. Acids, corrosives, and volatile materials are likely to attack electrical wiring and the
surfaces of optical components.
Keep air-borne dust particles to a minimum. Dust particles can cause permanent
damage to optical surfaces. Metallic dust can be destructive to electrical equipment.
Humidity
20% to 80%, non-condensing.
Important Note: Installation of the laser must be performed by a Candela
Service Representative. Following installation, a Candela Clinical Consultant
must instruct designated personnel on the basic operation and care of the
laser. An in-depth clinical training is required of a physician to become
proficient in the use of the AlexTriVantage Laser System.
