    2.1 Check before using Safety check Before using the WF1966, refer to the Safety precautions of this manual and confirm safety. Also, before connecting the power, refer to Section 2.2 Power source and grounding and thoroughly check the safety. Unpacking and repacking First, inspect the equipment for possible damage in shipping.

    For your safety, be sure to ground the device. Fuse To power switch Chassis Power source ! CAUTION Be sure to observe the following in order to prevent damage to the equipment. Confirm the power source voltage is within the range specified for the WF1966. WF1966...
  • Page 24 115V 230V Before using the WF1966 with a source voltage that differs from the factory setting, be sure to contact the sales representative of NF Corporation. Make sure that the power switch is off before connecting the power cable. Also, after switching power off, wait at least five seconds before switching the power on again.

    2.4 Conformable standards The WF1966 conforms to the following standards. Safety: EN 61010-1: 2001 EMC: EN 61326: 1997/A1: 1998/A2: 2001 However, the performance criteria for the following standards are as follows: EN61000-4-2(1995):C EN61000-4-4(1995), EN61000-4-5(1995), EN61000-4-11(1994):B The phase synchronization (φSYNC) operation may be required because the phase difference between channels is caused by the electrostatic discharge.
