• Xiria NGX with a LV topbox of 400 mm, this is equivalent to a minimum height of 1951 mm for the operating area. In the case of arc venting inside the switchroom via an arc chimney, the minimum ceiling height is 2400 mm.
Figure 3-1: Lifting equipment 3 panel section 3.2.1 Lifting WarNiNG The person in charge of lifting the Xiria NGX unit must hold a certificate from the relevant authorities confirming their authorisation to perform these operations. After lifting, the lifting equipment (1) must remain until the unit is positioned at its final location.
Each cable cone type C is provided with a “temporarily” mounted Allen key transport bolt M16 x 30 at delivery. These “protective’ bolts must be removed before connecting the cable. Figure 3-3: Cables are secured with plastic cable clamps Xiria NGX MN022012EN June 2024 www.eaton.com...
