Installation
3.5.2
Connect the pump to your electrical supply
Make the electrical connections to the pump motor with an IEC60320 cable socket (C19) that satisfies your local
electrical standards. To ensure CSA/UL compliance a suitable approved mains supply cord must be used; refer to
Table 10 for parts available from Edwards.
For recommended fuse ratings, refer to
in
.
CAUTION
If using an overload circuit breaker it must be of a time lag type because of the high start up current.
CAUTION
If using an earth leakage device e.g. an RCD, use at least a 30 mA rated unit to avoid trip during start up.
The pump will automatically restart after restoration of the power supply following power failure.
3.6
Inlet and outlet connections
CAUTION
The XDS100B cannot exhaust directly to atmosphere and must be backed by a suitable primary pump.
. Before you connect the pump to your vacuum system, remove the plastic cap from the inlet and
the exhaust, and ensure that the inlet strainer is fitted to the pump inlet port. Use appropriate NW40 vacuum fittings
for connection to your system.
WARNING
Ensure that the electrical installation of the XDS pump conforms with your local and national safety
requirements. It must be connected to a suitably fused and protected electrical supply with a
suitable earth point.
WARNING
If pumping dangerous gases or vapours, connect the exhaust of the backing pump to a suitable
treatment plant to prevent the discharge of dangerous gases and vapours to the surrounding
atmosphere.
WARNING
If the booster or backing pump is operated with the foreline or backing pump exhaust line blocked,
high pressures may be generated in the pipework.
