Hardware Connections - Hitachi HF-W2000 58 Instruction Manual

1. GETTING STARTED

1.7 Hardware Connections

Do not route interface cables and other cables (including cables for other devices, such as a
PC) near the power cord. Doing so might cause a failure or malfunction in the equipment.
Do not connect or disconnect an interface cable while the power for this equipment or for a
remote device is on. If you do so, a short circuit between the power supply and the ground
might cause a failure in the equipment. If an interface cable comes off while the power for the
equipment is on, shutdown the OS and unplug the power cord. Unplugging the power cord
without shutting down the OS might destroy internal files.
When you connect a cable for external contacts, connect the cable to a connector for the
external contacts (EXT). A voltage as high as 40 V DC might be applied to the cable through a
relay load. If you connect the cable to the wrong connector, this might cause a failure in the
equipment.
Before connecting any hardware, carefully read and ensure that you understand the content of the SAFETY
INSTRUCTIONS section of this document.
