Safety Considerations (contd)
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.
