Electrical Power
Vitronics Soltec electrical wiring design is based on the USA National Electrical Code
(NFPA-70 & 79) from the National Fire Protection Association guidelines and European
Standard EN 60204-1. Vitronics Soltec makes no claims or warranties for compliance to
any other standard or any local, state, federal or country codes, expressed or implied.

ovens are not equipped with a main circuit
breaker disconnect switch. A properly rated fused disconnect or main circuit breaker
switch, facility power cable and connection to the oven switch must be supplied by the
customer and installed by a qualified electrician in accordance with applicable regulations
and codes.
Estimating Power Requirements
Refer to the Electrical Configuration on the Purchase Order for the oven or the oven’s Nameplate Data to
determine the voltage. CAUTION: Incorrect voltage can result in extensive damage to the oven .
The Electrical values in the data tables are based on Vitronics Standard Factory Settings for power
management. Modification to the power management settings in the Oven Control Software may
render these numbers invalid

Power Connections
Connect the power and ground cables from the dedicated service (fused disconnect or circuit breaker) to the
power connectors located inside equipment access door located at the front-right corner of the oven. Connect
and secure the cables to the power and ground blocks. A hex wrench for socket head screws will be needed
to tighten the power connections after inserting the supply conductors. The Circuit Breaker also uses socket
head screws for securing the conductors.

Grounding
A dedicated equipment ground from the facility distribution panel for the oven is required to comply with Article
250 of the National Electrical Code. The equipment ground is necessary for the safety of personnel as well
for safe and reliable oven operation. All grounding and service wiring should be installed and tested by a
qualified licensed electrician.
Power Quality
• The oven control systems do not condition the facility supplied power to the oven .
• For proper operation, the power must be maintained at a "cleanliness level" of less than 10% of High
frequency (200V rise / microsecond) noise on the input voltage.
• The AC voltage supplied to the oven must be + 10% of the stated voltage. (For example 220 VAC must
be between 198VAC and 242 VAC).
• The voltage frequency must be within + 1% limit of the stated frequency.
• For 3 Phase power, any line to neutral voltage must be within + 5% of the arithmetic mean of the three line
to neutral voltages.
Any and all damage, service and costs resulting from poorly conditioned facility power is solely the
responsibility of the customer.
Power Distribution
A dedicated facility electrical distribution panel is recommended. Avoid powering heavy duty, electrically noisy
equipment from the same panel as the oven; such as:
• Heavy air conditioners
• Elevators
• Heaters
• Office equipment
• Fluorescent lights
• Air ionizers
• High current motors such as electric drills or water pumps
• Welders
• Placement equipment
Electromagnetic Fields
As with all electronically controlled equipment, the oven should be installed in an area not affected by
electromagnetic fields generated by other pieces of equipment.
Uninterruptable Power Supply Systems
Vitronics Soltec offers as and option, a UPS system for the oven which operates the oven conveyor, computer
/ control system and hood lifts for approximately five minutes after loss of facilities operating power. Consult
the purchase order for configuration. It is important to note that neither UPS option will operate the oven
heaters or cell fans.
