SAFETY

DANGER

HIGH VOLTAGE

RISK OF ELECTROCUTION

Observe extreme caution when working with this equipment

High voltage power supplies must always be connected to

protective earth

Do not touch connections unless equipment is turned off and

the capacitance of both the load and power supply are grounded

Allow adequate time for discharge of internal capacitance of the

power supply

Do not ground yourself or work under wet or damp conditions

Servicing Safety

Maintenance may require removing the Instrument cover with

the power on

Servicing should only be done by qualified personnel aware of

the hazards

Return to supplier for servicing

SÉCURITÉ

DANGER

HAUTE TENSION

RISQUE D'ÉLECTROCUTION

Observez une extrême prudence lorsque vous travaillez avec cet équipement

Les alimentations haute tension doivent toujours être connectées

au conducteur de protection.

Ne pas toucher les connexions à moins que l'équipement soit

éteint et que la capacité de la charge et de l'alimentation

électrique ne soit mise à la terre.

Prévoir un temps suffisant pour la décharge de la capacité

interne de l'alimentation.

Ne pas vous mettre à la terre ou travailler dans des conditions

humides.

Sécurité d'entretien

L'entretien ne doit être effectué que par un personnel qualifié et

conscient des dangers.

Il n'y a pas de piéce remplaçables par l'utilisateur dans l'unité,

retourner au fournisseur pour l'entretien.

2. Safety

The HV outputs of the units are considered hazardous, the protection against electric shock provided

by the units may be impaired if the units are not operated in accordance with the instructions in this

manual.

The units are contained in an earthed case with a screened HV output cable and the HV output cable

must be terminated safely before the units are operated.

This unit must be sourced with a double insulated or SELV 24 V dc supply.

The unit shall be properly bonded to the main protective earthing termination in the end product.

The units have been evaluated for use in a Pollution Degree 2, Installation Category II environment.

Consideration should be given to conducting the following tests with the unit installed in the end product:

a. Permissible Limits Tests with the unit installed in the end product.

b. Temperatures on accessible surfaces.

The units have not been the subject of a risk analysis; this should be done in the end product application.

2.1 Meaning of Symbols

SYMBOL

MEANING

Refer to manual before operating

Caution, possibility of electric shock

Protective conductor terminal (PE)

2.2 Regulatory Approvals

The unit is designed to meet the requirements of EN 61010-1, UL 61010-1 and CAN/CSA-22.2 No.

61010-1. Please consult datasheet or the factory for further approval information.

3. Installing the Unit

3.1 Initial Inspection

Inspect the package exterior for evidence of damage due to handling in transit. Notify the carrier and

Spellman immediately if damage is evident. Do not destroy or remove any of the packing material used

in a damaged shipment.

After unpacking, inspect the panel and chassis for visible damage.

Note: Failure to comply with the above could compromise the safe operation of the unit and invalidate

the warranty.

3.2 Mechanical Installation

The MXR units must be fitted in the end product and secured in position using screws.

The units must not be used in an environment with a level of pollution worse than Pollution Degree 2.

The units are intended for use as a component and no surface of the units should be accessible in the

end product.

3.3 Electrical Installation

The units should only be connected to a Category II environment, the units are not intended for

connection to the mains. The power for the units should be sourced from a UL recognised double

insulated or SELV 24 V dc supply. There is no external fuse.

The units shall be properly bonded to the main protective earthing termination in the end product via the

chassis.

The input and output connectors are not intended for field connections and should only be connected to

internal wiring in the end product. All external circuits connected to High Voltage outputs shall be

Double/Reinforced insulated from any accessible parts.
