Compatibility with RCDs

This product can cause a d.c. current in the protective grounding conductor. Where a
residual current-operated protective (RCD) or monitoring (RCM) device is used for
protection in case of direct or indirect contact, only an RCD or RCM of Type B is allowed
on the supply side of this product.
1.8

Extended temperature range

®
VACON 100 X has an integrated cooling system, independent from the motor fan. Under maxi-
mum operating conditions, the ambient temperature cannot exceed 40 °C. See Table and Table 29
for the output rated current. Higher temperatures are allowed only with derating of the output cur-
rent. With derating the unit can operate up to 60°C. See the Figure 5.

NOTE: the maximum allowed switching frequency above 50°C is 1.5 kHz.
The AC drive is cooled down by air-ventilation. Therefore, make sure that enough free space is left
around the AC drive to ensure sufficient air circulation (see for more details the mounting instruc-
tions on chapter 3).

Electro-magnetic compatibility (EMC)

®
The VACON 100 X complies with IEC 61000-3-12, provided that the short circuit ratio (R
greater than or equal to 120 at the interface point between the user's supply and the public system.
It is the responsibility of the installer or user of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the equipment is connected only to a supply with a
short-circuit ratio R
