Fit The Motor (Bareshaft Pumps Only); Electrical Installation: Single-Phase Pumps; Check And Configure The Motor; Connect The Pump To Your Electrical Supply - Edwards RV3 Instruction Manual

3.6

Fit the motor (bareshaft pumps only)

If you have a bareshaft pump, fit the motor to the pump now: refer to
3.7

Electrical installation: single-phase pumps

3.7.1

Check and configure the motor

Ensure that the motor is correctly configured for your electrical supply. If you operate the pump when the motor
is not correctly configured for the electrical supply, you will damage the motor.
Refer to Figure 4 for the item numbers in brackets.
Ensure that the voltage shown on the voltage indicator (4) in the motor-cover corresponds with your electrical supply
voltage. If it does not, you must change the configuration of the pump-motor to match your electrical supply voltage;
use the procedure below.
1. Undo the four screws, remove the cover-plate (1) and lift out the voltage indicator moulding (4).
2. Press the voltage selector switch (3) to select the alternative position.
3. Turn the voltage indicator moulding over so that the outer panel shows the required voltage. Refit the moulding.
4. Refit the cover-plate and secure it with the four screws.
3.7.2

Connect the pump to your electrical supply

Ensure that the electrical installation of the RV pump conforms with your local and national safety
requirements. It must be connected to a suitably fused and protected electrical supply and a
suitable earth (ground) point.
Notes: In the UK, if you use a 13 A plug, it must comply with BS1363A and be fitted with a 13 A fuse which
complies with BS1362.
To prevent automatic restart of the pump-motor if the electrical supply is restored after an electrical
supply failure, connect the pump to the electrical supply through suitable control equipment which
must be reset manually after an electrical supply failure.
Make the electrical connections to the pump-motor with an IEC 320 cable socket (cold condition type)
that satisfies your local electrical standards.
To maintain compliance with CSA standards, you must only use CSA/UL certified electrical supply cables
and connectors. Cables must be SJT rated (minimum) and must incorporate an earth conductor. The
conductors in the cable must be a minimum of 18 AWG. The temperature rating of the cable must be
70°C or greater.
