Edwards nEXT730D User Manual

The RS485/CAN/RS232 slide switch must be in the RS232 posion if either the TIC or TA
G
is to be used to control the nEXT pump.
5.4.3 Connect the logic interface to control equipment
To operate the pump using your own control system, use suitable connector mang half
(not supplied) to connect the control equipment to the connector on the logic interface
cable.
5.4.4 Connect the electrical supply
CAUTION:
This product r
equires a separate power supply (not included). The power supply
should be adequately protected against a hazardous live condion (for example, in
case of a short circuit).
CAUTION:
Incorpor
ate a suitable Emergency Stop Switch in the electrical supply. Locate the
switch in an easily accessible posion and mark it as the emergency disconnecng
device for the pump. Failure to do so will result in not being able to switch o the
pump in an emergency.
CAUTION:
Incorpor
ate a suitable fuse or current liming device in the 48 V d.c. supply line to
the pump. If this is not done and a fault develops, the pump may develop a
hazardous surface temperature or present a re hazard.
Refer to Table: Logic interface technical data for suitable fuse rangs.
CAUTION:
Do not ex
ceed the maximum supply voltage. Excessive supply voltage will cause
permanent damage to the control electronics and may result in a mechanical hazard
in some failure condions.
The electrical supply provided for the nEXT pump must meet the requirements of
UL61010-1 and EN61010-1. Ensure that hazardous voltages as dened in UL61010-1 and
EN61010-1 cannot be present on the electrical interface to the nEXT pump.
The nEXT pump 0 V is not referenced to earth (ground). Ensure that there is only one
path between 0 V and earth. Mulple connecons between 0V and earth must be
avoided in order to avoid unexpected oset voltages on control and status signals and
possible problems with serial communicaons. If no other connecon is present
between 0 V and earth, the connecon should be made at the power supply. Be aware
that other electrical equipment connected to the system could introduce a connecon
between 0 V and earth, for example a personal computer or measuring equipment.
To operate the nEXT pump using the customer’s own electrical supply, use a suitable
connector mang half (not supplied) to connect the electrical supply to the connector
on the pump power supply cable.
