Safety Considerations
WARNING:
FOR CONTINUED PROTECTION AGAINST FIRE, REPLACE THE LINE
FUSE(S) ONLY WITH 250V FUSE(S) OF THE SAME CURRENT RATING AND
TYPE (FOR EXAMPLE, NORMAL BLOW, TIME DELAY). DO NOT USE
REPAIRED FUSES OR SHORT CIRCUITED FUSEHOLDERS.
AVERTISSEMENT:
POUR LA PROTECTION CONTINUÉE CONTRE LE FEU, REMPLACER LE
FUSIBLE DE LIGNE (LES FUSIBLES) SEULEMENT AVEC 250V FUSIBLE
(LES FUSIBLES) DU MÊME COURANT ÉVALUANT ET TAPE (PAR
EXEMPLE, LE COUP NORMAL, LE DÉLAI). NE PAS UTILISER DE
FUSIBLES RÉPARÉS OU CIRCUITED FUSEHOLDERS COURT.

DC Power Supply (VDC Operation Model) Installation
Use a 15 Amp DC circuit breaker in series with the DC power source.
Do not connect the unit directly to a DC power source without the breaker.
14 AWG (1.5mm
2
) gage wire is the minimum gage permitted by the NEC for
DC power source hookup.
The Unit Chassis must be grounded for proper safety.
------------------------------------------------------------------------------------------------------------
WARNING:
ENSURE THAT A DISCONNECT DEVICE, SUCH AS A SWITCH, WITH THE
APPROPRIATE VOLTAGE/CURRENT RATING IS PROVIDED WHEN
CONNECTING A DC POWER SOURCE TO THE VDC OPERATION MODEL.
AVERTISSEMENT:
S'ASSURER QU'UN DÉBRANCHER L'APPAREIL, TEL QU'UN
COMMUTATEUR, AVEC LE CLASSEMENT DE TENSION/COURANT
APPROPRIÉ EST FOURNI EN CONNECTANT UNE SOURCE DE POUVOIR
DE DC AU MODÈLE DE CONFIGURATION DE VDC
.

Acoustic Noise Emissions
LpA<47 dB at operator position, at normal operation, tested per EN 27779. All data are
the results from type test.
Geräuschemission
LpA<47 dB am Arbeits platz, normaler Betrieb, geprüft nach EN 27779. Die Angagen
beruhen auf Ergebnissen von Typenprüfungen.
Electrostatic Discharge Immunity Testing
When the product is tested with 8kV AD, 4kV CD and 4kV ID according to IEC801-2, a
system error may occur that may affect measurement data made during these disturbances.
After these occurrences, the system self-recovers without user intervention.
