Page 5: Key Points Of Installation
Key points of installation 1.1 Install protectors very close to the power supply to be protected, either within the distribution panel or directly alongside it. 1.2 Mount units within a panel or WBX enclosure. 1.3 Units are installed in parallel. 1.4 Connect to phases, neutral and earth. - Page 6 1.8 Connecting leads should be 10 mm multi stranded cable. 1.9 Keep the connecting leads as short as possible and ideally less than 25 cm (10 inches) in length. This may be better achieved with the equivalent M1R with remote display mounting flexibility.

Page 7: Before Installation
Before installation 2.1 Check that the voltage between neutral and earth does not exceed 10 volts. If this voltage does exceed 10 volts, the installation is unsafe. Find and rectify the cause of this fault before proceeding. 2.2 Make sure that the supply voltage is suitable for the unit. Supply Rated Unit Voltage Voltage (VRMS) -

Figure 1: ESP 415 M1 installed inside a power distribution panel. Installation 3.1 Location Protectors need to be installed very close to the power supply to be protected. Usually the protector will be installed at a power distribution panel either inside it (Figure 1) or right next to it (Figure 2). - Page 9 Figure 2: ESP 415 M1 installed next to a power distribution panel. Alternatively, for three phase units, a remote display M1R option is available. These units can be installed within the power distribution panel with the remote display mounted on the front of the panel. Installation instructions for mains wire-in protectors | 3/2...

Page 22: Installation Check
Installation check The ESP unit should now be correctly installed. Switch the power supply on. Check that a green LED per phase and neutral is lit. See Figure 12. The unit is now fully operational. Watch the WARNING light for 30 seconds. If it is flashing or lit there is a problem with your installation (see opposite). -
Page 23: Neutral-Earth Warning Light
Neutral-earth warning light If the WARNING light is illuminated there is an excessive voltage present between neutral and earth. The WARNING light should never be illuminated. (a) Illumination at time of installation If the WARNING light flashes as soon as the mains supply to the ESP unit is turned on, one of the phase/live cables may have been connected to neutral and the neutral to phase/live. -
Page 24: Status Indication
The ESP protector should not be reconnected until the cause of the fault has been identified and rectified. Note: The ESP unit may have suffered damage - check the status indication (see section 6). Status indication ESP units give a continuous visual display of their status. They have a two colour indicator light, for each phase and neutral: Green only... -

Remote indication A remote indication of the reduced protection state is provided for linking the protector to a building management system, remote telemetry, PLC or directly to an indication light or buzzer. The unit has both a normally open and a normally closed volt free contact. - Page 26 The ESP units remote indication is rated at 1 Amp, 250 V Note: For reliable contact operation, the minimum permissible load is 10 mA, 5 V DC.

Page 28: Application Notes
Application notes 9.1 ESP coordination ESP M1/M1R units are designed to fully coordinate with ESP units of equivalent system voltage on the same installation. For example the ESP 415 M2 located at the main distribution panel would coordinate effectively with the ESP 415 M1 unit typically located at sub-distribution panels. - Page 29 Where ESP units are installed after (or downstream) of RCDs, special transient hardened RCDs (type ’S’) should be used (e.g. ABB F 200 A selective type series). 9.3 Insulation tests (flash testing) The ESP unit should be fully disconnected from the circuit before testing.
- Page 30 If possible the two units should be connected to the power supply a short distance apart either: (a) onto the first two outgoing ways (b) up to a metre apart on the incoming power supply 9.5 Installing three phase units on single phase supplies If a three phase unit is installed on a single phase mains supply (or a supply in which one or two phases are not in use), the ESP units spare (or unused) live terminal(s)
