Uuts Equipped With Three-Phase Connection - Unitest Telaris 0751 Instruction Manual

UUTs equipped with Three-phase Connection

6.9 UUTs equipped with Three-phase Connection
In compliance with DIN VDE 0701/0702, UUTs not
equipped with a "Schuko" plug can be connected to
the sockets 'L/N' (4) and 'PE' (5), connected in par-
allel to the test socket.
The following measurements may be performed:
• PE resistance
• Insulation resistance
• Substitute leakage current
Measurements of the touch current PE current,
the differential current or the function test can-
not be performed.
By using the three phase measurement adapter
(Cat.No. 1235, 1236) and the current clamp
adapter (Cat.No. 1245) also on three phase ap-
pliances the PE current could be measured.

The optional UNITEST Three-phase adapters 1240
and 1241 allow the direct connection of three-phase
appliances to the UNITEST TELARIS 0751 test sock-
et.
