5.1 Prepare connection
Always observe the following safety instructions:
• Connect only in the complete absence of line volt-
age
• If overvoltages are expected, VEGA overvoltage
arresters should be installed.
Provide a reliable separation between the supply
circuit and the mains circuits acc. to DIN VDE 0106
part 101. The VEGA power supply units VEGATRENN
149AEx, VEGASTAB 690, VEGADIS 371 as well as all
VEGAMETs meet this requirement. When using one
of these instruments, protection class III is ensured
for VEGABAR 14.
Bear in mind the following factors relating to the sup-
ply voltage:
• Reduction of the output voltage of the power sup-
ply unit under nominal load
• Influence of additional instruments in the circuit
(see Technical data).
VEGABAR 14 is connected with standard two-wire
cable. An outer diameter of 5 ... 9 mm ensures the
seal effect of the cable entry.
