1– INSTALLATION (COMPLETELY FILLED HERMETIC
TRANSFORMERS)
1.1 Preamble
The following installation procedure is given for information only. Automation 2000
cannot be held responsible for its execution.
1.2 Installation precautions
Before installing the DGPT2®, make sure that:
• The transformer is not powered.
• The transformer dielectric is at ambient temperature (approx. 20°C).
• The dielectric level inside the transformer is slightly below the transformer
tank cover.
• The transformer opening on which the DGPT2® will be installed is opened.
1.3 Installation procedure
• Remove the drain tap and the level indicator float.
• Fit the Viton® seal (supplied) in the DGPT2® attachment flange throat.
• Mount the DGPT2® on the transformer opening designed for that purpose.
• Attach the fixing hooks (supplied) on the fixing bolts (3 at 120° or
4 at 90°) according to the tightening precautions ( see page 4). The fixing bolts
must be located on a circle with a 97 mm diameter (±2 mm).
• Fill the DGPT2® with transformer dielectric until its level reaches the DGPT2 ®
highest point.
• Put back the level indicator float into place and close the DGPT2 ® with its
drain tap.

2– INSTALLATION (BREATHING TRANSFORMERS WITH
CONSERVATOR)
2.1 Preamble
The following installation procedure is given for information only. Automation 2000
cannot be held responsible for its execution.
2.2 Installation precautions
Before installing the DGPT2-IB, make sure that:
• The transformer is not powered.
• The transformer dielectric is at ambient temperature (approx. 20°C).
• The transformer conservator is empty.
• The dielectric level inside the transformer is slightly below the transformer
tank cover.
• The transformer opening on which the DGPT2-IB will be installed is opened.
2.3 Installation procedure
• Fit the Viton® seal (supplied) in the DGPT2-IB attachment flange throat.
• Mount the DGPT2-IB on the transformer opening designed for that purpose.
• Attach the fixing hooks (supplied) on the fixing bolts (3 at 120° or
4 at 90°) according to the tightening precautions ( see page 4). The fixing bolts
must be located on a circle with a 97 mm diameter (±2 mm).
• Connect the DGPT2-IB to the conservator through its IB insert with a flexible
tube equipped with both a 3/8” female threaded end and a rotary fitting.
• Fill the conservator up to its normal level.
• Slowly open the DGPT2-IB sampling tap until the transformer dielectric level
reaches the DGPT2-IB highest point and close it.

DGPT2® 3 4AUTOMATION 2000
TIGHTENING PRECAUTIONS
When you tighten the HM8 bolts on the DGPT2® fixing hooks, make sure that:
(cid:222) The tighten coupling is not higher than 3 m.kg (30 N.m).
(cid:222) The DGPT2® attachment flange DOES NOT TOUCH the transformer cover
(the Viton® seal should stay visible – approx. 1 or 2 mm).
(cid:222) The DGPT2® fixing hooks are tightened one after the other, clockwise in two
steps. During the first step, use a loose tighten coupling on all fixing hooks.
During the second step, use a tighten coupling not higher than 3 m.kg
(30 N.m).
LEAKPROOFNESS PRECAUTIONS
The DGPT2® drain tap’s leakproofness is insured by a Viton ® seal positioned at the root of
the screw thread undercut.
(cid:222) NEVER USE Teflon® tape (or similar tape) to insure the DGPT2 ® drain tap’s
leakproofness through its screw thread.

3– ELECTRICAL OPERATION
3.1 Preamble
All DGPT2 ® monitoring functions come with change-over contacts (a Normally
Opened contact, a Normally Closed contact and a Common point).
In the following diagrams, the contacts are shown unpowered
(dead), meaning not under the influence of any defect for
their respective monitoring functions.
