ELECTRICAL CONNECTIONS
WARNING
1.
This machine must be earthed
2.
Electrical installation of this machine must be carried out in accordance with all IEE
regulations and must be carried out by a qualified electrician.
1. Model CPL30S
This model
is powered by a
230 VAC, 50Hz, Single phase motor
,
Connect the mains lead to a 230V 50Hz electrical supply, having a fuse rating of 20amps.
IMPORTANT: A 13Amp plug MUST NOT be used with this machine.
The conductors in the mains lead are coloured in accordance with the following code:
Green & Yellow
-
Earth
Blue
-
Neutral
Brown
-
Live
As the colours of the flexible lead may not correspond with the coloured markings identifying
terminals in your electrical supply, you should proceed as follows:
Connect the Green & Yellow conductor to terminal marked with the letter ‘E’ or Earth
symbol “ ”, or coloured GREEN or YELLOW & GREEN.
Connect the Brown conductor to the terminal marked with the letter ‘L’ or coloured RED
Connect the Blue conductor to the terminal marked with the letter ‘N’ or coloured BLACK
9.2 Model CPL30T
This model is powered by a
400 VAC, 50Hz,three phase motor
. and connection should be made
through a fused isolator having a delayed fuse rating of 20Amps.
The conductors should be connected as follows:
Connect the Green & Yellow conductor to terminal marked with the letter ‘E’ or Earth
symbol “ ”.
The other conductors should be connected, one to each of the three available phases.
It is
IMPORTANT
to ensure that the phase connections are correctly made, so that the motor turns
in the correct direction of rotation. i.e. when the UP button is pressed the arms are raised, conversly
when the DOWN button is pressed they are lowered.
If the arms lower when the UP button is pressed, it will be necessary to reverse two of the three phase
connections in order to reverse the direction of rotation of the motor.
When testing the machine, ensure all precautions are taken as previously described.
IMPORTANT:
Connection must be made via a fused isolator, located close to the machine so that it is
easily reached by the operator. We further recommend that a Residual Current Device
(RCD) be used.
NOTE: It may be necessary to replace the mains cable, supplied with the machine, with one of a
more suitable length for your installation. Ensure the conductor sizes are at least the same as those
in the cable supplied.
WARNING
The trailing cable from the machine to the mains supply MUST be protected in accordance
with IEE regulations.
