Installation
IMPORTANT - For hazardous area installations, you must refer to the installation (IM) manuals supplied with the system.
Location of MSP900SH
•
Install the transmitter above the liquid surface using the bracket provided.
•
Do not mount the MSP900SH on a structure that is subject to vibration, or in a position where damage may be caused by
impact or thermal stress.
•
The equipment is not intended for use in areas exposed to dust.
•
The equipment must not be installed directly in any process where the enclosure might be charged by the rapid flow of
non-conductive media.
Location of MCU901
•
The MCU901 must not be located in a hazardous area. Do not mount the MCU901 where it is subject to vibration, or in a
position where damage may be caused by impact, thermal stress or liquid ingress.
•
The MCU901W is housed in a tough IP65 enclosure. If mounted outside, it is recommended that the unit be protected from
direct heavy rain.
•
The MCU901P is a standard DIN size designed for direct mounting in a control panel. It is designed for panel mounting in a
weatherproof environment.
Cabling (MCU901W)
.
1
Cable the MSP900SH to the MCU901 using the gland provided. (Undo 2 screws and lift cover away to reveal terminals).
2.
Check the voltage selector switch (230V or 115V) and adjust if necessary. (Mains unit only).
3.
Cable the power lead to the MCU901 using the gland provided. Do not apply power yet.
4.
Make connections to relay terminals and current output terminals, if required.
5.
Seal unused cable entries with the blanking plugs provided.
6.
Replace and secure the terminal cover.
Cabling (MCU901P)
1.
Cable the MSP900SH transmitter to terminals 1, 2 and 3 on the rear panel of the MCU901.
(See figure inset, right)
2.
Check the voltage selector switch (230V or 115V) and adjust if necessary. (Mains unit only).
3.
Cable the AC power supply to terminals 28 (Live) and 29 (Neutral) on the rear panel of the
MCU901. Note that mains Earth is not required. (Mains unit only).
4.
Connect terminal 30 to an Intrinsically Safe Earth. This is essential only if the MSP900SH
is in located in a hazardous area.
