Electrical shock and fire hazards. Make sure that the user-supplied power cord and non‐locking plug
meet the applicable country code requirements.
Electrocution hazard. Make sure that the protective earth conductor has a low impedance connection of
less than 0.1 ohm. The connected wire conductor must have the same current rating as the AC mains
line conductor.
The instrument is used for a single phase connection only.
Cord installation: The manufacturer recommends to use the optional cord and sealing gland. Refer
to the maintenance manual for the replacement parts list. For a customer-supplied cord, three
