Section 2 Precautions Before Use
2-2.
2.1 Installation Site Environmental Conditions
The 156/622M POS modules operate normally within a temperature
range of 0 to 40°C. Avoid using them under the following conditions to
prevent malfunctioning:
•
Excessive vibration
•
Excessive moisture or dust
•
Direct sunlight
•
Possible influence of active gas
•
Severe temperature fluctuation
CAUTION
After using the 156/622 POS module for a long time in low
temperatures, moving them to a location with higher
temperatures may create dew inside the module. In this
event, sufficiently dehumidify the module before turning
the power On. Turning the power On when dew is present
inside may cause a short circuit and damage the module.
2.2 Connection with Device Under Test
When connecting a device being tested (Device Under Test: DUT), be sure
to check the input/output signal power level. Inputting a signal exceed-
ing the ratings may destroy the internal devices resulting in a failure.
Also avoid connecting output connectors to each other because it may
cause failure.
