1. Introduction

NOVA is a flexible and accessible platform which is designed to be easy to use. However, proper training and supervision is required to ensure safe operation. As with any lab equipment, NOVA and the accompanying materials and modules should be handled with care and you should read this manual carefully before using NOVA.

NOVA is for use as-is. Any modifications to the machine or improper use, including unauthorized repairs, without explicit approval or direction from Voltera, may damage the machine or cause bodily harm and will void your warranty.

In case of emergency or prior to performing any Voltera-directed hardware maintenance, please ensure that the power cable is disconnected from NOVA.

2. Markings and warning statements

All users of the machine must read this safety information carefully before using NOVA. Improper use of NOVA or use in a manner not specified by Voltera may result in impairment of protections and may present hazards such as electric shock, crushing injuries, or pinch points.

2.1 Mechanical hazards

Gantry Bridge, Module Hub, and Smart Probe

Keep hands away from NOVA when the system is moving to avoid injury.

The Gantry Bridge and Module Hub can produce pinch hazards when the system is in motion. When the Smart Probe is mounted, it can also produce similar hazards. Stay clear to avoid these hazards while the machine is in use.

Precision nozzles are sharp

Handle precision nozzles with care when using the Smart Dispenser. The precision nozzles can pierce skin and lead to injury when being handled and when the Smart Dispenser is mounted on NOVA.

Ensure hands are clear of the machine when the Smart Dispenser is in use and the system is in motion. Take care not to get caught on nozzles when mating precision nozzles to the Smart Dispenser.

2.2 Hot surfaces

Smart Dispenser heater

The Smart Dispenser contains a 12W heater that heats to a maximum of 65°C (149°F), and if damaged, this temperature can reach 80°C (176°F). Take care when handling a hot dispenser.

2.3 Application-specific inks, materials, and cleaning agents

Material safety is the user’s responsibility

It is your responsibility to be aware of the hazards created by the materials used in your application. Ensure you take necessary precautions to ensure that inks, substrates, and cleaning agents will not cause a hazard on their own, or as a result of a reaction with one another or NOVA.

Read all relevant safety data sheets (SDS) for your application before working with NOVA. Materials provided with NOVA are non-hazardous and non-volatile.

2.4 Electrical connections

Only mount approved modules

Never touch the electrical contact pins while the locking lever on the Module Hub is engaged. NOVA will only accept Voltera approved modules.

Ensure power adapter is accessible

Ensure that the connecting power adapter is easily accessible when using the machine, including the connection to NOVA. Do not place the power adapter in a place that is difficult to reach.

2.5 Use personal protective equipment

Hearing protection

NOVA contains vacuum pumps which can be loud at maximum power. Wear hearing protection if the pumps are run above 30% duty cycle for extended periods.

Eye protection

Wear eye protection if using the Smart Probe module with custom fixturing, printing on 3D structures, or when using mounting accessories. If the Smart Probe’s stylus accidentally contacts a hard surface during travel, it can fracture and create shrapnel.

Protective gloves

Wear protective gloves when handling conductive inks, solvents, or other electronic materials. Consult the SDS before using.

2.6 Two person lift

Heavy equipment

NOVA weighs 35 kg (77 lb.) and should always be lifted by two people to avoid injury. Use proper lifting technique when relocating. Failing to do so can cause muscle strain or back injury.

Place NOVA carefully, as dropping the equipment can cause serious harm. When moving NOVA, each person should lift by the base with two hands. Do not lift the machine by the bridge/gantry in order to maintain proper calibration of your unit.

2.7 Do not disassemble

NOVA is not user-serviceable

Any modifications to the machine without explicit approval or direction from Voltera may damage the machine, may cause bodily harm, and will void your warranty. Except at the express direction of Voltera, do not open or disassemble NOVA, or any Voltera modules, or equipment.
