Page 11: Safety Precautions
This product uses a line filter and must be grounded to avoid the risk of electric shock. To prevent electric shock, be sure to safely implement grounding according to local electrical safety codes. The EC1000S is automatically grounded when the 3-prong power plug is connected to a 3-prong power outlet with a protective grounding contact.
Page 12  Prevention of electrical shock due to output voltage The maximum output of the EC1000S is 400 V. Carefully operate the EC1000S to avoid electrical shock. Directly touching the output or changing cable connections while output is on may cause electrical shock.
