Note: MOPD will decrease if the coils will be used at 60Hz frequency. Also follow the operating instructions of the used devices.
S a f e t y i n s t r u c t i o n s :
• Read operating instructions thoroughly. Failure to comply can result in device
failure, system damage or personal injury.
• According to EN 13313 it is intended for use by persons having the
appropriate knowledge and skill.
• Do not exceed the specified maximum ratings for pressure, temperature,
voltage and current.
• The coil should be fused in accordance with local codes. Electrically ground
the valve body.
• Ensure that the system piping is grounded.
• Before installation or service disconnect all voltages from system and device.
• Do not energize coil unless it is attached to the device.
• Observe and avoid mechanical damage of component housing.
• Ensure that design, installation and operation are according to European and
national standards/regulations.

• Mount O-ring with smaller diameter (1) over enclosing tube.
• Place coil over the enclosing tube and press it down by hand.
• Place the black retainer (2) on the upper visible end of the enclosing tube. The two
slots of the retainer fit to stumps of ESC coil. (5)
• Insert O-ring with larger diameter (3) inside of the orange screw cap
• Press coil well down and tight the screw cap (4) over the retainer first hand tight
and then with torque 0.5-0.6 Nm in order to provide IP65 protection. Use spanner
size 27mm.
E l e c t r i c a l c o n n e c t i o n :
• Entire electrical connections have to comply with local regulations.
• Before energizing the device, be sure that the source voltage and frequency
matches that on the coil label.
• Standard plug and cable assembly (ASC-N...)
Brown and blue color wires (BN & BL Fig. 2) to be connected to the power supply
and yellow/green color wire to the ground. Connect pre-wired plug to the coil and
tighten screw with 0.2 Nm.
• Plug and cable with electronic chopper module (DS2-N15)
Polarity protected two wires to be connected to the power supply.
• Wiring with DIN Plug (Fig. 3)
Cable with three wires has to be connected to terminal 1 and 2 and
the plug terminal box. Connect pre-wired DIN-plug to the coil and tighten screw
with 0.2 Nm.

Warning:
• ESC coils are intended for continuous-duty, which when energized for an
extended period of time, it becomes hot. This is normal. Do not touch the coil
during operation. Wait for coil temperature to cool down before attempting
to dissemble it, or use gloves, failure to do so could lead to injury.
• Disconnect electrical power before service.
• Dismantle of ESC: unscrew the screw cap (4) and pull the coil with retainer (2)
out. Remove smaller O-ring.
• Replacement of ASC.../ ASC3... with ESC series:
- Dismantle ASC... by opening blue clip (Fig.4)
- Dismantle ASC3...: see Fig. 5. Remove smaller O-ring.
- To ensure proper function and protection, only O-rings approved for ESC coils
may be used. Any existing O-rings must be replaced.
