General Safety Instructions
WARNING
High Voltage! Only a qualified electrician can carry out the electrical
installation of this filter.
High voltage is used in the operation of this filter. Use Extreme caution to avoid
contact with high voltage when operating, installing or repairing this filter.
Injury or death may result if safety precautions are not observed.
WARNING
The opening of the branch circuit protective device may be an indication that a
fault current has been interrupted. To reduce the risk of fire or electrical shock,
current-carrying parts and other components of the filter should be examined
and replaced if damaged.
An upstream disconnect/protection device must be used as required by the
National Electrical Code (NEC) or governing authority.
Even if the upstream disconnect/protection device is open, the drive
downstream of the filter may feedback high voltage to the filter. The drive
safety instructions must be followed.
Injury or death may result if safety
precautions are not observed.
The filter must be grounded with a grounding conductor connected to all
grounding terminals.
Only spare parts obtained from MTE Corporation or an authorized MTE
distributor can be used.
After removing power, allow at least five minutes to elapse and verify that the
capacitors have discharged to a safe level before contacting internal
components. Connect a DC voltmeter across the capacitor terminals and ensure
that the voltage is at a safe level.
Caution
Loose or improperly secured connections may damage or degrade filter
performance. Visually inspect and secure all electrical connections before
power is applied to the filter.
Product should not be mounted on wood or any other combustible surface.
Doing so could lead to fire or damage to the product.
The user of this filter must assure that the input voltage and frequency is
correct for the filter rating and that the voltage applied falls within the rated
operating tolerance envelop specified for the filter. For severe power line
applications where the power feed is likely to experience surges and transients
that exceed the input voltage rating, it is recommended that a TVSS (Transient
Voltage Surge Suppression) or SPD (Surge Protection Device) be deployed
ahead of the filter to reduce the possibility of exceeding the filter rated voltage.
Consult with TVSS or SPD manufacturer to determine the correct protection for
your power line conditions.
Filter must be mounted in the proper orientation per labeling.
