1. Safety instructions
•
Read instruction manual carefully before operating the device! Keep for later
reference.
•
Mounting and installation must be carried out by suitably qualified and competent
persons only.
•
WARNING: The measurement inputs of the device can carry life-threatening
voltages!
•
WARNING: When working on the device hazardous voltages must not be
connected to the device! The terminals J1-J6 are not isolated from the
measuring circuit.
•
DANGER: When the USB port is connected, only voltages lower than 50 V
may be applied to the measurement inputs. The USB port is not isolated
from the measurement circuit.
•
At the maximum current strength (10 A), 500 mW of waste heat is generated at
the current sense resistor. The tip of the current sense resistor becomes very hot
(87 °C). Maintain the appropriate safety distances and pay attention to good
ventilation!
•
The device is not intended to protect persons or facilities against harm. Specific
devices must be used to guarantee safety (protection relays, cut-off switches,
etc.).
•
When connecting switches to the terminals J1-J6, only switches must be used
whose isolation voltage is at least twice the maximum occurring measurement
voltage. For example, when measuring 250 V AC switches must be isolated for at
least 500 V.
•
Do not open the housing!
•
Do not use the device in the presence of explosive or flammable substances!
•
All cables carrying hazardous voltages must be secured with external separators.
