6 Maintenance, storage and disposal
Before any maintenance work on the R&S ENV216 is executed, read the Safety
Instructions carefully.
The device does not need to be regularly maintained. Maintenance is limited essen-
tially to wiping the device's external surfaces. See
"Cleaning the product" on page 6.
6.1 Device safety inspection
A device safety inspection of the network as defined in BGV A3 is not possible
because of the design according to CISPR 16-1-2 (EN 55016-1-2) and measurement
set-up according to CISPR 16-2-1 (EN 55016-2-1). Therefore, the following examina-
tions must be carried out as a minimum requirement.
6.1.1 Visual inspection
Ensure that parts relevant for active and passive safety are not visibly damaged or
even unsuitable for use in the device.
1. Remove the R&S ENV216 from the mains supply.
2. Let the R&S ENV216 cool down to ambient temperature.
3. Check the following parts for damage:
a) Housing, displays, carrying handles, air vents
b) Device connection cables, connection points and mains lead cleats
c) Mains plug, fuse holder
d) Labeling and markings, warning notices
e) Isolated parts, wiring insulation
f) Plug connections and clamping points
g) Vent and leakage paths must not be altered unacceptably.
If any damage is detected, remove the R&S ENV216 from the test environment
and contact R&S customer support. See Chapter 6.4, "Contacting customer sup-
port" , on page 28.
6.2 Testing the PE grounding connection
This test is intended to determine whether the resistance between contactable parts,
which must be securely grounded for safety reasons, and the grounding contact of the
mains connector is less than 0.3
Ω
.
During the measurement, the entire length of the wire is to be moved in sections. If a
change in resistance is noted while part of the wire is being moved, the fault must be
