Installing The Pressure Option; Setting The Option Modules; Setting The Mechanical Position Indicator - ABB PositionMaster EDP300 Operating Instruction

5.3.3

Installing the pressure option

CAUTION – Minor injuries!
Risk of injuries due to flying components as well
as significant noise emissions.
Prior to disassembly, all connected compressed
air lines must be depressurized.
IMPORTANT (NOTE)
The supply voltage must be switched off before
the pressure option is installed.
IMPORTANT (NOTE)
The bond wires for the pressure option must not
be touched. Doing this will cause damage to the
option module.
IMPORTANT (NOTE)
Before using the device, an IEC-compliant high-
voltage test must be performed.
