2. The metering valve is not shipped with any field wiring attached (such as
pigtails) but rather is provided with internal terminal blocks for field wiring.
These terminal blocks are located under the explosion-proof covers on the
actuator and resolver housings.
3. The non-metric actuator housing has two 0.750-14 NPT taps, and the
resolver housing has two 0.750-14 NPT taps. The metric actuator housing
has two M25 x 1.5 taps, and the resolver housing has two M25 x 1.5 taps.
4. The resolver wires need to be run through the wiring connection in front of
the 10-pole WAGO terminal block. The actuator power wires should go
through the other wiring connection.
The terminal blocks provided for the motor resolver wires and the position
resolver are WAGO 264 series. These terminal blocks are top-load terminal
blocks and are actuated by inserting a DIN 5264 screwdriver into the opening
behind the wire slot. Once the cage clamp has been opened, the wire can be
inserted and the screwdriver removed (see the illustration and instructions
below).
1. Insert the screwdriver into the operating slot up to the stop.
2. The screwdriver blade holds the clamping spring open automatically so that
the conductor can be introduced into the clamping unit.
3. Withdraw
the
screwdriver. The conductor is automatically clamped.
