CHAPTER 2: IMPORTANT SAFETY INFORMATION
2.2 ELECTRICAL REQUIREMENTS
110 V UNITS
All Matrix 3x, 5x, 7xe and 7xi 110 V bikes require the use of a 100-125 V, 60 Hz and a 15 A
“Dedicated Circuit”, with a non-looped (isolated) neutral/ground for power. This outlet should be a
NEMA 5-15R and have the same configuration as the plug. No adapter should be used with this
product. These bikes can be daisy-chained together with up to 4 units per 15 A dedicated circuit.
Matrix daisy-chain cord adapters are sold separately.
220 V UNITS
All Matrix 3x, 5x, 7xe and 7xi 220 V bikes require the use of a 216-250 V, 50 Hz and a 15 A
“Dedicated Circuit”, with a non-looped (isolated) neutral/ground for power. This outlet should be a
NEMA 6-15R and have the same configuration as the plug. No adapter should be used with this
product. These bikes can be daisy-chained together with up to 4 units per 15 A dedicated circuit.
Matrix daisy-chain cord adapters are sold separately.
DEDICATED CIRCUIT AND ELECTRICAL INFO
A “Dedicated Circuit” means that each outlet you plug into should not have anything else running on that same circuit. The easiest way to verify
this is to locate the main circuit breaker box, and turn off the breaker(s) one at a time. Once a breaker has been turned off, the only thing that
should not have power to it are the units in question. No lamps, vending machines, fans, sound systems, or any other item should lose power
when you perform this test. Non-looped (isolated) neutral/grounding means that each circuit must have an individual neutral/ground connection
coming from it, and terminating at an approved earth ground. You cannot “jumper” a single neutral/ground from one circuit to the next.
ELECTRICAL REQUIREMENTS
For your safety and to ensure good unit performance, the ground on this circuit must be non-looped (isolated). Please refer to NEC article 210-21
and 210-23. Any alterations to the standard power cord provided could void all warranties of this product.
The 3x, 5x and 7xe bikes are designed to be self-powered and do not require an external power supply source to operate. Without an external
power supply, the console’s start-up time may be delayed. Add-on TV’s and other console accessories will increase the time needed for start-up.
An external power supply will ensure power is provided to the console at all times and is recommended when add-on accessories are used.
For units with an integrated TV (like the 7xe and 7xi), the TV power requirements are included in the unit. An RG6 coaxial cable with ‘F Type’
compression fittings on each end will need to be connected to the cardio unit and the video source. Additional power requirements are not
needed for the add-on digital TV (3x and 5x). For units with an add-on PCTV (3x and 5x), the TV power requirements are separate.
North American power cord plugs shown.
Depending on your country, the plug type may vary.
GROUNDING INSTRUCTIONS
The unit must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce
the risk of electric shock. The unit is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be
plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances. If the user does not
follow these grounding instructions, the user could void the Matrix limited warranty.
ADDITIONAL ELECTRICAL INFO
In addition to the dedicated circuit requirement, the proper gauge wire must be used from the circuit breaker box, to each outlet that will have the
maximum number of units running off of it. If the distance from the circuit breaker box to each outlet, is 100 ft (30.5 m) or less, then 12 gauge wire
should be used. For distances greater than 100 ft (30.5 m) from the circuit breaker box to the outlet, a 10 gauge wire should be used.
ENERGY SAVING / LOW-POWER MODE
All units are configured with the ability to enter into an energy saving / low-power mode when the unit has not been in use for a specified period
of time. Additional time may be required to fully reactivate this unit once it has entered the low-power mode. This energy saving feature may be
enabled or disabled from within the ‘Manager Mode’ or ‘Engineering Mode.
ADD-ON PCTV (3X AND 5X)
A 15 A or 20 A “Dedicated Circuit” with a non-looped (isolated) neutral/ground is required. Each PCTV requires at least 1.2 A of current. No more
than 12 PCTVs should be used for each 15 A circuit and no more than 16 PCTVs should be used for each 20 A circuit. The power outlet should
have the same configuration as the plug. No adapter should be used with this product. An RG6 coaxial cable with ‘F Type’ compression fittings
will need to be connected between the video source and each add-on PCTV unit. See the PCTV Manual for web connection requirements.
ADD-ON DIGITAL TV (3X AND 5X)
Additional power requirements are not needed for the add-on digital TV. An RG6 coaxial cable with ‘F Type’ compression fittings will need to be
connected between the video source and each add-on digital TV unit.
BATTERY CHARGING (3X AND 5X)
The bike saves its batter charge by moving into a shutdown mode whenever PEDAL FASTER appears on the display. If the user does not
maintain a pedal rate of 40 RPM or higher, a 30 second shutdown process begins. When the battery voltage is low, LOW BATTERY appears
on the display. This means it is time to recharge the battery. If the battery must be charged, use the optional power adapter charging unit. The
charger should be connected to the bike for a minimum of eight hours to ensure a thorough charge.

CHAPTER 3: PREVENTATIVE MAINTENANCE
3.1 RECOMMENDED CLEANING TIPS
In order to maximize life span, and minimize down time, all Matrix Fitness Equipment requires regularly
scheduled cleaning.
YOU WILL NEED:
- Mild dish soap and water mixture in a spray bottle (10:1 water to soap ratio).
- Vacuum / Shop Vac with extendable hose and soft brush attachment.
- Corrosion Block (available from Matrix - part # ZMS4001374).
DAILY:
1. Wipe down the unit after each use with a mild dish soap and water mixture. NOTE: Spray the soap / water mixture onto the cloth.
NEVER spray directly onto the equipment. We recommend that you do NOT allow customers to use spray bottles to clean the equipment. If
the cleaner is sprayed directly on the equipment or overspray is present, it may cause your equipment to rust and / or cause damage to con
sole overlays.
WEEKLY:
1. With a clean dry 100% lint free cloth and water / soap mixture, wipe down the entire frame so it is free of dust, dirt, and sweat.
2. With a clean dry 100% lint free cloth and water / soap mixture, wipe down the entire console area including the hand grips and hand rails.
MONTHLY:
1. Vacuum under and around the Bike. If you need to move it, unplug the unit first.
2. Remove the shrouds and use a vacuum to remove any dust or dirt built up under the covers. NOTE: Be careful not to damage or unplug
any of the wiring.
3. Apply Corrosion Block to the metal part of the iPod cable.
-
3.2 CHECK FOR DAMAGED PARTS
DO NOT use any equipment that is damaged or has worn or broken parts. Use only replacement parts supplied by Matrix Fitness Systems.
MAINTAIN LABELS AND NAMEPLATES. Do not remove labels for any reason. They contain important information. If unreadable or missing,
contact Matrix Fitness Systems for a replacement. 1-866-693-4863, www.matrixfitness.com
MAINTAIN ALL EQUIPMENT Preventative maintenance is the key to smooth operating equipment. Equipment needs to be inspected at regular
intervals. Defective components must be replaced immediately. Improperly working equipment must be kept out of use until it is repaired.
Ensure that any person(s) making adjustments or performing maintenance or repair of any kind is qualified to do so. Matrix Fitness Systems will
provide service and maintenance training at our corporate facility upon request or in the field if proper arrangements are made.
