UL-compliant installation
INFORMATION
Due to UL requirements, the following chapter is always printed in English independ-
ent of the language of the publication.
Field wiring power terminals
Observe the following notes for UL-compliant installation:
• Use 75 °C copper wire only
• MOVIFIT
®
uses cage clamp terminals.
Short circuit current rating
Suitable for use on a circuit capable of delivering not more than 200 000 rms symmet-
rical 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
®
MC, max. voltage is limited to 500 V.
Branch circuit protection
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.

lent.
Device and line protection
MOVIFIT

MC: Units equipped with ABOXes MTA...-M14-.. or MTA...-M15-.. are provi-
ded with device protection and line protection.
Ambient temperature
MOVIFIT
®
MC is suitable for an ambient temperature of 40 °C, max. 60 °C with derat-
ed output current. To determine the output current rating at higher than 40 °C, the out-
put current should be derated at 3.0% per °C between 40 °C and 60 °C.
