Guidelines for Electrical Installation

7.3.4 Mounting rails
All mounting rails must be mounted onto the mounting plate with a low impedance, over a large
surface area, and must be correctly earthed. Use corrosion-resistant mounting rails
Mount the mounting rails over a large surface area and with a low impedance to the support system
using screws or rivets.
Remove the isolating layer from all painted, anodized or isolated metal components at the connection
point. Protect the connection point against corrosion (for example with grease; caution: use only
suitable grease).
