Ensure that the instructions provided in this document are followed completely. This section also provides guidelines for selecting the measuring and testing devices.
Installation
The device (or system) must be installed in an access-controlled location.
Tighten the thumbscrews by using a tool after initial installation and subsequent access to the panel.
Ground
Do not damage the ground conductor or operate the device in the absence of a properly installed ground conductor. Conduct the electrical inspection carefully.
The device (or system) must be connected permanently to the protection ground before
an operation. The cross-sectional area of the protective ground conductor must be at least 16 mm2.
The device must be fixed securely on the floor or other reliable objects, such as the walls and the mounting racks before operation.
When installing the unit, always make the ground connection first and disconnect it last
Power Supply
For DC-supplied model: The device applies to DC power source that complies with the Safety Extra-Low Voltage (SELV) requirements in IEC 60950-1 based safety standards.
Prepared conductors are connected to the terminal block, and only the appropriate AWG/Type of wire is secured with the lug terminals.
This device relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 80 VDC, 30A for DC supplied model is used on the phase conductors (all current-carrying conductors).
For this device, a readily accessible disconnect device shall be incorporated external to the equipment
