AANWIJZING
Ongeacht de taal van het document dat voor u ligt, wordt het volgende hoofdstuk
vanwege de UL-vereisten altijd in het Engels afgedrukt.
Observe the following notes for UL-compliant installation:
•
Use 75 °C copper wire only
•
MOVIFIT
®
uses cage clamp terminals.
Suitable for use on a circuit capable of delivering not more than 200,000 rms symme-
trical amperes when protected as follows:
For 240 V systems:
250 V minimum, 25 A maximum, non-semiconductor fuses
or 250 V minimum, 25 A maximum, inverse time circuit breakers
For 500 V systems:
•
MOVIFIT
®
-FC, max. voltage is limited to 500 V.
Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical
Code and any additional local codes.
For maximum branch circuit protection see table below.
