5 Electrical connection
• The unit must be connected by a qualified electrician�
• The national and international regulations for the installation of electrical equip-
ment must be adhered to�
• The unit complies with overvoltage category II�
• Caution: For the output circuit the same protective measures as for the supply
circuit must be taken�
•
Insert a miniature fuse according to IEC60127-2 Sheet 1 (≤ 5 A fast acting).
• The permissible potential difference between supply and output circuit is max�
300 V�
• The metal parts of the housing must be properly grounded� For this, you can,
for example, attach a grounding clip to the connector and ensure the grounding
using a potential equalisation cable�
• The design of the unit corresponds to protection class II�
• Due to the integrated EMC filters, leakage currents of typ� < 0�5 mA can flow
via the potential equalisation to the earth potential�
• If several units are used in parallel, take into account that the leakage currents
add�
• The applicable standards must be adhered to�
