into the existing ambient temperature before switching it on. Do not
expose the XH-303 Web Panel to direct thermal radiation from heat-
ing appliances.
CAUTION
UV LIGHT
Plastics will become brittle when exposed to UV light. This artificial
aging will reduce the XH-303 unit's lifespan. Protect the XH-303 unit
from direct sunlight and other sources of UV radiation.
CAUTION
POINTY, SHARP OBJECTS AND CORROSIVE LIQUIDS
When cleaning the XH-303:
l
Do not use any pointy or sharp objects (e.g., knives).
l
Do not use aggressive or abrasive cleaning products or solvents.
Make sure that no liquids get into the XH-303 unit (short-circuit haz-
ard) and that the XH-303 unit is not damaged in any way.
CAUTION
INSTALLATION CUT-OUT
The mounting cutout must be located in a position that will not defeat
the purpose of stabilizing webs or other reinforcing elements in the
control panel. If necessary, reinforcing elements must be installed/ad-
ded.
An IP65 degree of protection will only be ensured if there is sufficient
stiffness, the device is properly mounted using the original fixing
material and the gasket has a proper seat
l
Minimum sheet thickness of control cabinet where the device will
be flush mounted:
2 mm (0.08") ≦ d ≦ 5 mm (0.2")
CAUTION
When using commercially available peripheral devices (e.g., with the
USB port), it is important to keep in mind that their EMC interference
immunity parameters may render them unsuitable for use in industrial
environments.
The USB port on the XH-303 Web Panel is intended exclusively for
maintenance work.
